I did a lot of shooting this weekend with the Sony A57 and 24-70mm f/2.8 Carl Zeiss lens using the New Ver 1.02 Firmware, and was able to test out the incredible 12fps feature!! Here is what Sony officially claims the feature can do:
“By capturing the center 2/3 of the image sensor (8.4MP), Tele-zoom high speed shooting brings the action closer with a 1.4x effective increase of focal length. Shoot up to an incredible 12 frames per second with continuous auto focus and auto exposure to capture the decisive moment. “
To test this feature out I wanted a subject that was moving away from me or towards me, and it just so happen that Layla and Chloe were both running on the deck in front of me on Saturday.
Check out this first burst of images I took of Layla running towards me.
Also be sure to Click on the photos for the large crisp version!!
100% Crops so you can see for yourself the focus is accurate on almost all of them.
Here’s another Burst of images, but this time it’s a harder target, Cloe running towards me with here toy!!

Buffer Size Testing
Per the comments below we had a request to test the buffer size, and here are the results:
Ok I tested the buffer size and here is what I got using my Sandisk 8gb 30mb/s Extreme HD video Memory card.
12fps mode only allows jpeg medium size so I got about 22-23 shots before the buffer filled up,then it went about 1-3 shots every second or so.
10fps mode I was able to shoot raw and I got 18 shots before the buffer filled up,then it was about 1 shot a second.
10fps mode Jpeg mode large I got 20 shots before the buffer filed up, then it was about 1-3 shots per second
10fps mode Jpeg mode medium I got 22 shots before the buffer filed up, then it was about 1-3 shots per second
Not to bad in my opinion, and it would be even better with a faster memory card!!
Here’s a shot of Cloe in the Direct Sun as she was sitting on my Dad’s lap.
I am absolutely blown away by the 12fps Mode hit rate being pretty much 100% for my three test bursts above. I still need to test this on something a bit faster like my quad or something, but still Layla and Cloe were running at me, and the camera was at an aperture of f/3.5 which creates a really narrow depth of field. The Sony was able to nail the focus shot after shot better than my Canon 5D Mark II ever has. Granted that is not a sports camera, but the focus is incredible good so it’s worth noting the comparison in my opinion. Way to go Sony!!
If your in the Market for a new Camera I highly recommend checking out the Sony A57!! Sony really hit it out of the park with this camera and the more I use it, the more it impresses me.
One other note about the EVF (electronic view finder) it is not as good as the OLED in the A77, but it’s definitely better than the other one that was in the A55. It’s totally usable and does the job perfectly for my purposes.
