Product Description

The Sony SLT-A77 Mark II (a77 II) is the company's latest midrange DSLR to use Translucent Mirror Technology.

a defective unit. Take or send it back to your retailer or send it for Sony service. Everything will work out just fine. Continue Reading

As new as this camera is I would contact the dealer for an exchange rather than sending it back to Sony for repair.  Sony repairs often tak a very long time and others who have sent this new camera in had problems and a very long wait due to lack of parts availability. Continue Reading

Have you tried to "INITIALIZE" your camera using the menu, to do a reset. If it doesnt help, yes, definately take it in for a replacement. Continue Reading

A77ii technical question: "Zoom" versus "Focus Magnifier"

I've just upgraded from my A580 to a A77ii and I'm still finding my way through the new functionality. With my A580, I loved Focus Check Live View which lifted the mirror (ah, that old SLR design!) and allowed me to zoom in to fine tune focus. With the A77ii, it has a "Zoom" capability but that doesn't work when I shoot RAW (which I do). Initially, I was very disappointed but then I discovered that there is a "Focus Magnifier" functionality that I can assign to the button. Phew. But what is different about how the Zoom and Focus Magnifier functionality is implemented and why does shooting RAW matter? And why does the camera make a faint continuous buzzing noise when I am using Focus Magnifier even when SSS and AF are off? What moving parts are left once you turn off SSS & AF?

Focus Magnifier changes only the view presented to you - it doesn't change the recorded image at all. Zoom changes (crops) the recorded image. Apparently, live view stabilization (SteadyS w shut.) is enabled... which means you did not turn off SS for still shots. Maybe you only turned off SS for movies. Continue Reading

Ah! I see. Thanks for clarifying. That sounds pretty useless; how could it be better than cropping during post-processsing? Especially since it can't be used in RAW mode. I'm suprised that it is the default instead of Focus Magnifier. I'm relieved that I'm able to change the button function. Nope. I just double-checked. Both SS settings are off. It's a faint sound and may just be an electronic buzz. There is also a click when I half-press the focus button. I am curious about that too. Note that this is just curiousity - not concern. So far, I'm impressed with the camera and glad to be back to the 7-series. As much as I like the A580, I missed some of the controls that were available on the Minolta 7D. Continue Reading

Just a guess, but perhaps the A77ii enables the SS while in magnify mode to help manual focus as things can get a bit shaky at high mag, unlike previous models the A77 turns on SS at half press to help viewing while shooting. Older models just have it on during the shot. Continue Reading

Tethering Sony A77 M2 with Adobe Lightroom.. for PCs

There doesn't seem to be an easy supported way to tether the A77 M2 to the PC, but there is a workaround with Lightroom. Install Lightroom and setup up Auto Import to a selected folder.  Then run a programme like Sony's Remote Camera Control programme for your PC.  The Sony Remote Camera Control software will allow you to both use the programme to control your camera from the pc with loads of options, and will also be the link to the PC if you use the actual buttons on the camera.  Set the default directory of those photos to go to the same folder as Lightroom has on Auto Import watching.  When a photo you take goes to that folder, Lightroom will detect it and automatically import it into Lightroom. Also make sure your camera's USB setting when connected to the pc is selected for PC Remote. If I have time I will see if I can test out any other programmes that allow PC Tethering for Sony as for some reason it isn't generally supported.

Thanks for the info. -- Tom Look at the picture, not the pixels ------------ Misuse of the ability to do 100% pixel peeping is the bane of digital photography because it causes people to fret over inconsequential issues. Continue Reading
