SLT-A77, first impressions

Sony SLT-A77

On August 24th Sony has released the SLT-A77 camera. It took a while before it became available in Europe, but I recently bought one. Here are my first impressions of the camera.

You will not find 100% crops of highest-ISO shots in this review. This is not my shooting style, and it's not my review style. You will also not find detailed descriptions of all features and menu items. There are many reviews out there where you can read about this. I have linked to some here. What I write about here are my impressions of the camera in real-life use, and other thoughts. Obviously the A77 is compared a lot with its predecessor, the A700, and this review is no exception. You can read what I thought about that camera in my review of the A700. I did not buy the new 16-50/2.8 lens. It's still not available here, and I'm not sure if I will buy it when it is. I already own the 16-80/3.5-4.5, which has served me well as a standard zoom lens.

The good…

Obviously the biggest difference between the A700 and the A77 is that the A700 is a traditional DSLR with a flip-up mirror, matte screen and optical viewfinder, and the A77 has a fixed semi-transparent mirror which diverts light to the AF sensors, while the remaining light falls onto the main sensor, which provides both the viewfinder image and the recorded image. The viewfinder itself is an XGA resolution OLED with ocular optics. There is no direct light path between the lens and the photographer's eye.

The system is very similar to what I have described in “The future of digital SLRs”. The main difference is that SLTs do not rely on slow contrast AF, but use the faster phase detect AF.

Having an electronic viewfinder brings a lot of advantages: you can have a bright viewfinder image even when it's dark (or during DOF preview), you can have all kinds of overlays and markings, you can zoom into the image during manual focus, and it's easy to have a large 100% WYSIWYG view. Sony has improved the viewfinder considerably compared to the A33/A55/A35. The resolution is higher, it's brighter, and the image update is faster. There are a few disadvantages, like a slightly higher power consumption, and the dynamic range is not quite as large as with an optical viewfinder. But the resolution and refresh rate is high enough. Overall, I rate the advantages higher than the disadvantages.

The fixed mirror enables something that comparable cameras of other brands can not offer: really fast phase detect AF with live view and especially during movie recording. There also is no mirror flipping up and down, producing a lot of noise. The mirror diverts ⅓ of the incoming light towards the AF sensors. This sounds like a lot, but actually it's only about ½ stop. The mirror sheet itself does not have a negative influence on image quality, or at least I have not seen any.

The camera can not only record still images, but also Full HD (1920×1080) movies with up to 50 (or 60, depending on regional model) frames per second. I have not used this much, yet, but I certainly will. The image is stabilized also in movie mode. This, however, is not accomplished by shifting the sensor, but by shifting the image readout-area on the sensor (electronic stabilization). For this, the image area is slightly cropped during movie recording. The advantage is that overheating the sensor is avoided, which would otherwise limit the maximum recording time per take.

There are many improvements in the focusing area. There are more AF sensors (19), and more of them are cross-type (11). There is also the new AF Zones mode. In this mode, you select one of three groups of AF sensors to be active: the left group, middle group or right group. For example, when you know your subject is in the left part of the frame, you can select the left group, and AF will not be distracted by objects in the center part or right part of the frame. In earlier cameras, you could of course select a single sensor in the left part of the frame. But a single sensor covers only a smaller area, and when you miss the subject with the single sensor, AF may loose the subject completely. This does not happen so easily with the AF Zones mode.

There's also the new Object Tracking (or Tracking AF) mode: When you activate this mode with the joystick center button, you point the camera on the object you want to track, and then the camera will select the AF sensor(s) closest to the object, following the object's movements in the frame. This works quite well in good light, and when the object is sufficiently distinct from to the background. When you move the camera, or when the object itself moves, the camera will select AF sensors that allow to focus on the selected object. In low light, however, the camera looses the object easily. But to deactivate this mode, you just have to press the center button, and you're back to the previous AF mode, so you can recover quickly.

In case you want to focus manually, the new Focus Peaking mode is a big help: areas of the image with a high edge contrast are highlighted with a selectable color in the viewfinder. When Focus Peaking is enabled in the menu, it activates automatically whenever you are in MF mode. It also is activated when you are in DMF mode and after AF has locked. So when you then touch up focus manually, Focus Peaking will assist you. Furthermore, Focus Peaking also works with adapted lenses (even without electronics), with the STF lens, and when the focus magnifier is activated. Focus Peaking is a great tool that Sony has ported from video cameras, first to the NEX series and now to SLT cameras.

The studio flash socket is now under a larger cover, together with the remote release socket. The studio flash cover of the A700 was quite flimsy and protruding from the body, and I can imagine that it was ripped from a good number of A700s.

The A77 has 6 fully configurable positions of Creative Styles. For each position, you can select one out of 13 effects, together with the image parameters contrast, saturation and sharpness. The A700 had 4 positions with a fixed effect, and 3 configurable positions.

The mechanics of the built-in flash have changed compared to the A700. As with earlier entry-level bodies, the flash now moves forward and up to open. This allows having accessories like an external microphone mounted on the flash shoe while the flash is open. The obvious disadvantage is that the flash does not rise as high above the lens axis as before. In fact, the built-in flash has crept lower and lower from the 7D to the A700 to the A77. But since the flash also has moved forward, the danger of casting a shadow with the lens has not increased much.

The A700 only had rubber on the front of the grip and a small patch on the rear side of the body. On the A77, the entire grip is rubberized, front and back, except for the (smaller) memory card door. This improves the handling of the camera and ensures a form grip. The body also is officially weather sealed, although the sealing of the battery compartment and of the memory card door is nearly non-existent. It doesn't leave the impression of being able to withstand really bad weather. But in the past, I didn't have any problem with the 7D or A700, either, and typically the photographer gives up before the camera.

The button layout on the top plate was improved. While some buttons were hard to reach on the A700 while actually holding the camera, this is not the case with the A77. These buttons were moved towards the front, and the top LCD takes the place at the rear. The On/Off switch is now located around the release button (Nikon style). It doesn't take long to get used to this, and afterwards it's actually more comfortable than the old style.

Finally, the vertical grip, the VG-C77AM, was also improved. While I was hoping that the old grip, the VG-C70AM, may be compatible with the SLT-A77, it is not. The new grip is very similar to the old one. What has changed are the two lower buttons and the design of the joystick. The new grip also has a strap eyelet on the left side of the grip, next to the battery compartment door, just where it was missing on the old grip. This eyelet lets me attach the strap to the left side of the camera.


A few things have been reported as a problem in other reviews, which I either could not reproduce or which I consider non-problems:

… the bad…

One of the biggest problems I found was that many features are unavailable when you select RAW format or RAW+JPEG. This is quite understandable for the features that take multiple frames and produce a single JPEG from them, like HDR, the panorama modes, multi-frame NR, etc. But it's a mystery to me why the Picture Effects are unavailable in RAW+JPEG mode. Sure, they involve considerable image processing, but then why not produce an unprocessed RAW file (with meta-information) as usual, and only apply the effect to the JPEG file? Why, for example, is the Creative Style “Black and White” available in RAW+JPEG mode, but not the similar Picture Effect “High Contrast Mono”? What's the big difference? You can not even select a smaller JPEG image size when you select RAW+JPEG format. This, by the way, was possible with the A700: you got the full-size RAW image and the scaled-down JPEG image.

What makes this even more inconvenient is that you can no longer change the image quality and size with the Fn button. Again, this was possible with the A700. You now have to go to the menu to change them. So when you're in RAW mode and you want to take a HDR shot, you first have to go to the menu, switch to JPEG-only mode, then go back to the main screen, switch to HDR mode with the Fn button, and when you're done, you have to go to the menu again to switch back to RAW mode.

This really should not be necessary. So, Sony, if some feature has an effect only on the JPEG image, please let us still shoot in RAW+JPEG mode and simply produce a RAW file without the image effect. It works with the Creative Styles, white balance, DRO, 16:9 cropping, etc., and there's no reason it can't work with everything else, too. Even better, for the features requiring multiple frames, please produce a RAW file containing at least the first frame. Or yet even better, please invent an ARW format that can contain multiple frames per file, so that we can, for example, reproduce a HDR shot from the original RAW frames.

The next big problem I see is that in movie mode, recording can not be started with the normal release button. This is understandable when the camera is in still image mode. Then you need a second release button to quickly start movie recording as opposed to taking a still image. But when you switch to movie mode with the top mode dial, the release button is simply dead. The red movie button is the only way to start and stop recording. Even worse, you can not start and stop movie recording remotely, neither with the wired remote release, nor with the RMT-DSLR1 wireless remote release. YouTubers must be very disappointed that Sony makes it so hard for them to film themselves. I, too, consider this a big oversight which should be fixed.

The reaction time of the control wheels is too long. While this was presumably improved from firmware 1.02 to 1.03, it's still not good enough. The camera's reaction noticeably lags behind the control wheels. This was improved in firmware 1.05.

The advantage of an electronic viewfinder is that you can have a number of different markers and overlays. The camera can display various grids, shooting parameters, a live histogram, and markers for the movie area and AF sensor locations. The problem with these currently is that they are always drawn in black. This makes them quite difficult to see in darker parts of the frame. A better way to draw the markers would be to invert the background pixel instead of drawing a fixed color. Then you'd get white markers on black background, red markers on blue background, etc.

Both the viewfinder and the rear display now have configurable sets of screens. With the DISP button, you can cycle through the enabled screens. What I'm missing is a “display off” option for the rear display. Currently the only way to turn off the rear display is to reverse it. So you only have the choice between draining the battery and wearing out the hinges of the screen, instead of just pressing a button.

There is also a small quirk with the “For Viewfinder” option for the rear screen: When it's active and you press the Fn button, you can not change the settings within this screen. Instead, the camera temporarily switches to the “All info” screen.

When you press the Fn button and select a setting to change, or when you select the setting directly with a dedicated button, you can cycle through the main options with the front wheel and the sub-options with the rear wheel. The icons that the camera displays for these options are quite small, and especially the Picture Effect icons are difficult to distinguish. There is plenty of screen area, so Sony should have used larger icons. As it is now you're often forced to press the joystick to get to the detailed option screen and see larger icons and help text.

The A77 allows to customize the AF/MF, ISO, AEL and WB buttons. You can select from a long list of functions to be activated with these buttons. This is all nice. But an advanced user, the intended target market for this camera, will likely use the ISO button to change ISO, the WB button to change white balance, etc., so this customizability is mostly wasted. On the other hand, the ? button is completely unused in normal shooting mode (help is available only in the menu), and advanced users likely will not need it, anyway. It would be nice to be able to customize this button instead of the others. There also no longer is a C button with no fixed function, as there was on the A700. It would be nice to have one. The lens button can be customized, but only with two options (AF stop and DOF preview). It would be nice to have the full list of functions for this button, too.

The rear display attachment is very flexible. A little quirk is that the automatic switchover to the viewfinder is disabled when the rear display is not flat against the camera back. This is obviously to avoid switching to the viewfinder when you flip the screen up and cover the viewfinder sensor with it. But this feature may surprise you when you have the display flipped down, look into the viewfinder, and nothing happens. Luckily, there is a button on the camera to override the automatic switchover.

The camera's built-in lens correction feature only works with a few select lenses. At least Sony has promised to add more supported lenses with future firmware updates.

A number of features were removed compared to the A700:

… and the ugly.

And then there are some things that can only be called bugs:

And then there's the mysterious Demo Mode: the manual is very vague about this menu option, and in fact, it seems to be always disabled. With or without a card inserted, with or without HDMI connected, in AUTO mode or any other mode, this item is never enabled. To this day, I don't know what it does.


The A77 is a worthy successor of the A700. Its improvements, the addition of movie recording, and the innovative SLT technology are very welcome. The camera has a solid hardware base, but the software still needs significant bug-fixing and polishing. Let's hope that Sony does not drag their feet with this.

Sample images

These images were taken end of October/beginning of November near Nuremberg/Germany and at the Leipzig Zoo.

#1: Kommentar von Atto am 13. November 2011, 10:43:52 Uhr:
Thank's for the interesting review!

I can fully support your findings. Once the firmware will be updated this camera will be extremely usable.

Regarding 16 50 2.8:
It's a parfocal, constant aperture, sealed, quiet ssm lens. I hope many Sony lenses with this attributes will follow.
#2: Kommentar von Andrew am 14. November 2011, 18:19:32 Uhr:
How do you find using graduated ND filters with A-77 ?
I can't see a difference especially in low light, but even in normal light I'm never sure where gradation starts. I don't know if I'm doing something wrong or is it just the reality with SLT cameras.
Michael Hohner antwortet:
Compared to the A700, the filter appears about the same in the viewfinder. In low light, the A700 viewfinder is dimmer, and the A77 viewfinder is noisier. But in both I can see the transition zone of the filter.
#3: Kommentar von revdocjim am 15. November 2011, 15:40:05 Uhr:
Great review! I mentioned it on dyxum too, but you can turn off the rear display by selecting manual switching between EVF and LCD. Then just select the EVF by pressing the small button on the right side of the hotshoe.
Michael Hohner antwortet:
But then you also have to manually switch to the rear display before you can review images there, or display the menu. On the A700 you can turn off the rear display, and as soon as you review images, it will automatically turn on. And of course, you also need an extra button press before you can use the viewfinder.
#4: Kommentar von Miguel Rozsas am 19. November 2011, 02:40:42 Uhr:
Thanks for this review, specially for the bad and ugly section; I will buy this camera even after knowing it is not perfect. At least I known what to expect for good and bad, and at end, I think it worth the price!
#5: Kommentar von DG am 22. November 2011, 22:44:37 Uhr:
I hope Sony firmware developpers read this review.
And add a feature to control audio levels in video mode.
#6: Kommentar von Theo am 27. November 2011, 21:47:08 Uhr:
Hi Michael,
Thanks for this clear review.
Obviously you have chosen for APS-C format versus full format. Any thoughts you can share on the basis for that decision?
Michael Hohner antwortet:
Well, how many full-frame Sony DSLRs with movie capability, live view and built-in flash are there to choose from?
#7: Kommentar von Heiko Herrmann am 29. Dezember 2011, 01:38:36 Uhr:
"The new grip also has a strap eyelet on the left side of the grip, next to the battery compartment door, just where it was missing on the old grip. This eyelet lets me attach the strap to the left side of the camera." - Even better, you can attach one on the bottom of the camera, so that you can hold the camera secure in the strap while holding it in portrait mode.
#8: Kommentar von Wolfram Rinke am 13. Januar 2012, 09:58:01 Uhr:
Hi Michael,
thank you for the detailed review. What is the firmware release level you had installed on your A77. You mentioned an upgrade from 1.02 to 1.03, but did something improve based on your observations to firmware 1.04 ?

Michael Hohner antwortet:
For firmware 1.04, see the other article.
#9: Kommentar von Tom am 22. Februar 2012, 17:52:46 Uhr:
Despite what you say there is a crop difference between stills and movie mode. Because the A65/77 use electronic SSS in movie mode a smaller area of the sensor is used so the crop factor changes from 1.5 to 1.8. This is good/bad. Good for telephoto bad for wide angle. On the wide end 18mm changes from 27mm equiv to 32mm. At 300mm it changes from 450mm to 540mm. Overall I think it's well worth it for the considerable increase in recording time with SSS.
Michael Hohner antwortet:
I have mentioned the crop in movie mode.
#10: Kommentar von Wolfram S. am 29. März 2012, 11:33:30 Uhr:
Nice review. I agree completely with you on "the bad" and "the ugly", and I may add a minor point to these sections which persists with firmware 1.05:

AEL is cancelled when switching to image review or when enlarging or changing the image in auto review (I use AEL toggle, and all previous alphas I know incl. A55 keep AEL until explicitly cancelled by the user).

Regarding firmware 1.05: Nice speed improvements, but unfortunately your "the bad" and "the ugly" list has to stay otherwise unchanged.
#11: Kommentar von Wolfram Rinke am 1. April 2012, 08:28:51 Uhr:
There is another firmware bug, that I have found recently after installing FW 1.05.
When shooting in RAW+JPG mode the JPG compression mode should be set to "fine" and format size to "L" for the JPG. The JPG image sizes stay that size consistant, but the image quality changes sometimes depandent what the setting was before and if you switched to other functions between a JPG shot and a RAW+JPG shot. So the FW does not initialise the JPG quality properly. This bug is not new but existed already in FW 1.03, which I noticed after reviewing previous shots.

Regards, Wolfram
#12: Kommentar von Michaela Meyer am 9. Mai 2012, 14:05:42 Uhr:
Hi Michael,
great review and brilliant Website!!!

In case you are still wondering about the "mysterious Demo Mode", I have some explanations:

Demo mode is aimed at photo dealers when they have the cameras on display in the shop and they want to show videos repeatedly on the LCD. When you set "Demo Mode" to "on" and you have a memory card inserted that contains videos, the videos will automatically start playing back when stand-by time is elapsed (instead of entering stand-by videos will be played back). This gave some people, including me, a fright when the camera suddenly seemed to do its own thing... On the other hand you can use this function to stop the camera from entering stand-by. Simply put a memory card in that contains NO videos and set "Demo Mode" to "on".
This is the normal behaviour of A33/A55/NEX-3/NEX-5.

On A67/A77/NEX-7 the option "Demo Mode" is not available until the camera is powered by AC adapter AND a memory card is inserted. Apart from that it is the same behaviour as described above.

I cannot say for sure how A35/A57/NEX-C3/NEX-5N behave, but when the option is greyed out and not available in the menu, you need an AC adapter and a memory card to activate it.

Keep up the good work!

Michael Hohner antwortet:
Thanks for the info. I do not have an AC adapter for the camera, so the menu item was never enabled, even with a memory card with videos inserted.
#13: Kommentar von Billy S. am 3. Juli 2012, 18:36:56 Uhr:
Michael...thanks for sharing your knowledge and expertise...I own a Sony a700 and am contemplating upgrading to the a77...I love my G series Sony 70-300 lens and am wondering if you have any experience with the a77 coupled with this lens...Billy
Michael Hohner antwortet:
I don't own the lens, but a co-worker owns the 70-300 G and the A77. Obviously they work fine. Firmware 1.05 also added lens correction support for the 70-300 G.
#14: Kommentar von Christian Ellsworth am 20. Dezember 2012, 20:46:40 Uhr:
Michael great page, the place to research for my camera, i Have a A57 and when i'm using a Minolta 50 F1.7 lens, the lens keeps playing with the AF, even when the camera is hanging form my neck. this does not happens with the SAL18-135 when used. any clues why?
Michael Hohner antwortet:
Do you have eye-start AF activated? If you have, the viewfinder sensor may be activated when the camera hangs in front of your body, and AF starts and tries finding focus.
#15: Kommentar von Jens Rasmussen am 21. Januar 2013, 12:47:53 Uhr:
As Minolta 7D and Sony a700 user I would like to know if there are any here on the blog who have experience with how Sony a77 and Minolta AF 300/4 APO + 1.4 converter works.
How fast is the autofocus compared to the a77?

#16: Kommentar von Maxxuman am 28. Januar 2013, 20:44:10 Uhr:
In response to Jens, I've been using the A77 with Minolta 300/4 and APO 1.4 converter and it works well. It does seem to AF a little quicker than on my A700 and while I sometimes have issues with focus hunting a little back and forth, it doesn't seem to hunt through the full range as often as happened with my A700. I was also surprised that the focus gears seem a lot quieter on the A77.
#17: Kommentar von Jakub am 7. Februar 2013, 09:22:23 Uhr:
Another thing that is missing in A77 in comparison with A700 is ZONE parameter that is great in use with creative styles - in fact it allows to change the expositon by -1/2...+1 EV without change to appearance of image apart of widened tonal range in shadows (mode -1) or highlits (modes 1,2). As you can use ZONE with any ISO, it's much more convenient than old Lo80 or Hi200 modes of A100 and gives excellent results with A700 CMOS sensor.
Michael Hohner antwortet:
The A77 has certain picture effects that accomplish similar results.
#18: Kommentar von Ralph am 18. Februar 2013, 19:10:55 Uhr:
Hello Michael, thanks for your AF77 impressions. Could you also share your experience on the AF - did you ever experience issues with the "AF hit rate"? I dont mean (correctable) front/back focus but "AF hit rate" in general. Have there been differences within the latest firmware releases?
Michael Hohner antwortet:
My targets are mainly (near) static, so I can't say much about the AF hit rate with (fast) moving targets. AF was improved in firmware updates, mainly in combination with specific lenses. I generally recommend using the latest version (currently 1.07).
#19: Kommentar von ferruccio am 24. Februar 2013, 15:26:37 Uhr:
Hi, I would like a clarification on the A77 translucent mirror, if during the 'use the mirror becomes dirty with dust or other that they should not be able to blow it off for any reason there is a system to clean the mirror a bit like if you should clean the sensor or dirt on the mirror has no bearing on 'image? traditional mirror is raised and certainly does not affect the image while remaining fixed this might affect?

Salve, vorrei un chiarimento riguardo lo specchio traslucido della A77, se durante l' uso si dovesse sporcare lo specchio con polvere o altro che non si dovesse riuscire a soffiarla via per qualsiasi motivo esiste un sistema per poter pulire lo specchio un pò come se si dovesse pulire il sensore o lo sporco sullo specchio non influisce sull' immagine? lo specchio tradizionale si solleva e non influisce sicuramente sull'immagine mentre questo rimanendo fisso potrebbe influire?
Michael Hohner antwortet:
If there is just dust on the mirror, I would not try to clean it aggressively (i.e. with more than just air). While the SLT mirror is in the light path during exposure, it's also far away from the plane of focus. Dust you can see in the image is usually directly on the sensor, not on the mirror.
#20: Kommentar von ferruccio am 24. Februar 2013, 16:22:25 Uhr:
Does not interfere with the image even if there should be a partial accident during the lifting of the mirror as I've seen on network video web? (I repeat that it is not my case and it is only a preliminary information should they experience any of these problems)
Non interferisce sull'immagine nemmeno se dovesse esserci un'impronta parziale accidentale durante il sollevamento dello specchio come mi è capitato di vedere su video in rete web? (ripeto che non è il mio caso ed è solo una informazione preventiva nel caso dovesse verificarsi uno di questi problemi)
Michael Hohner antwortet:
Not sure what exactly you mean with “partial accident”. If you manage to damage the mirror, it should be replaced.
#21: Kommentar von ferruccio am 24. Februar 2013, 17:13:15 Uhr:
Unfortunately, that is the translation is not exact, it is not an accident but a partial fingerprint partial.
Purtroppo è la traduzione che non è esatta, non è un incidente parziale ma una impronta digitale parziale.
Michael Hohner antwortet:
You should be able to clean the mirror with the usual sensor cleaners. Of course, it would be much better to not touch the mirror in the first place.
#22: Kommentar von Ferruccio am 25. Februar 2013, 20:31:10 Uhr:
Interesting to know that if necessary you can clean the sensor cleaning kit, certainly as a last resort.
Thank you very much for your suggestions and I congratulate the timely responses to questions and extensive information on the website.
Interessante sapere che se strettamente necessario si può pulire con il kit di pulizia del sensore, certamente come ultima soluzione.
Ringrazio molto per i suggerimenti e mi complimento per le risposte tempestive alle domande e alle estese informazioni del sito.

A quand l'af en mode video M ? gros souhait !!!
Michael Hohner antwortet:
Phase detect AF requires the aperture to be (nearly) wide open. If you'd use M mode and close the aperture, AF would stop working, anyway. That's why the camera only allows to combine P mode with AF.

This test is about the A77, not the A57. The latest firmware for the A57 is indeed 1.04.
