Product Description

The Sony SLT-A77 Mark II (a77 II) is the company's latest midrange DSLR to use Translucent Mirror Technology. TMT allows the camera to have fast continuous AF (at 12 fps) while retaining live view on the electronic viewfinder or LCD. It features a new 24.3MP CMOS sensor and an enhanced 79-pt phase detect autofocus system with roughly 40% coverage across the frame. Like its predecessors, the a77 II uses the A-mount and has built-in image stabilization. Other features include a tilting 3" LCD, XGA OLED electronic viewfinder, and 1080/60p video.

Questions & Answers


Does Sony Alpha A77 II has Auto ISO in Manual Mode?
vermaden asked
15 days ago


I actually argue exactly the contrary. M + AutoISO is the only mode I need. Set A and S manually for what I want and the camera has no choice but to work out the calculations in real time of 18% grey exposure of what I point my meter/focus point at. And as I understand  it, the a77 m2 allows compensation in this mode. You just need to use the appropriate metering mode. Continue Reading

When you use Auto ISO in M, the camera doesn't favour anything. It is a slave of the scene brightness and your selection of metering method, exposure compensation, shutter speed and aperture. In P, A and S modes it makes sense to talk about favoring since the decision on how to balance Auto ISO with other settings will be up to the camera. Continue Reading

Was the photo properly exposed? If it was then your expectation of proper ISO was incorrect. Continue Reading

Sony a77 m2 - SS / AF Noise

Hey guys, I've had the a77 m2 for a couple months now. Just got back from Zion/Red Rock/Vegas/VoF and she did great with the 16-50mm lens. I've moved up from a a57 (which I loved) so Sony is not new but I've noticed with the a77 that either when it is focusing or maybe the steady shot is making some kinda noises that I've not heard before. It doesn't seem to be getting any worse but just curious to see if anyone else was noticing this. The noise is apparent when the shutter is half engaged (and after a couple secs) I use the Sony SAL1650 SSM and the Tamron 70-200 f2.8 USD

Does it matter what lens you have on? The stabilization system is running in half press.  Some people report hearing it. I could not hear it and I pressed my "good ear" to the body with it on when testing in a store.  And In confirmed it was on and set lower shutter to make sure it would be used. Nice Shot!

You probably have the stabilization in viewfinder option enabled. When I tried it out with my Tamron 70-200mm and purposefully moving the camera around, I could hear/feel it.  It wasn't annoying, just...there.  But I have since turned that option off since, while neat, I find only useful when shooting at longer focal lengths where the need to have a stabilized view preceding the shot can aide in getting the shot.

Where is the setting to turn this off ? I would like to do so when I'm using my 1650. Thanks ! Continue Reading

Nikon D810 Video question???

Seeing the 4k is the king system of video that Sony7s has provided... I did not see anything mention the 4k for video will be in the Nikon D810. Perhaps I may have by past it.. The rest of the camera look really good.. I ONLY wished they had the LCD screen to tilt .. SIMILAR TO SONY A77 MARK II The advantage having a tilt screen is really nice Do enjoy your days ahead TOM

The OP is a troll who works for Sony or has stock or something...... Every single thread he makes is pro-Sony, anti-D800/anti-Nikon: Its OK to have a personal preference, but with his strong hatred of the D800, its obvious that he's just trolling.  This kind of person should be banned from the forum.  Its just hostile.

I want to say 4k is useless, but then I would sound like one of those people that claim 36mp is useless. Truth is it would be really helpful for cropping and image stabilization in post. Really though nikon needs to figure out how to deliver high quality 1080p 1st. If you are serious about video an external recorder is the only "good" solution as it is, Nikons .mp4 compression is kind of crap. Continue Reading

You did not miss it, the D810 does not have 4K. These are the movie specs: HD 1,920x1,080 / 60 fps HD 1,920x1,080 / 50 fps HD 1,920x1,080 / 30 fps HD 1,920x1,080 / 25 fps HD 1,920x1,080 / 24 fps HD 1,280x720 / 60 fps HD 1,280x720 / 50 fps Continue Reading
