Sony α77 Specs Leaked

Photorumors has gotten ahold of the specs for the upcoming Sony α77 cropped sensor pro camera. The camera is expected to be announced on August 24, 2011. While the specs hold great promise, many pros I have corresponded with are on the fence about this camera due to Sony’s use of an Electronic View Finder (EVF) instead of a traditional optical one. Though not listed below, the OLED EVF is supposed to sport around 3 million pixels which would make it the highest resolution EVF on the market to date.

Analysis
Sony’s latest offering in the Alpha bloodline brings together pro level and consumer level features. Targeted for both aspiring amateurs and professional photographers, the Sony SLT-A77 sports consumer features like 2D/3D Panoramas, Face Recognition, scene modes, picture effects and a “Smart TeleConverter” function. This last one has me a bit puzzled. If this is a cropped sensor camera (1.5x crop) does the Smart TeleConverter function (which has 1.2x and 2.0x settings) stack atop of that? Or is this actually a full frame camera, using the sensor from the Sony A900 (or a refreshed design of said sensor)?
On the pro side, the body is built of magnesium alloy and is weather and dust sealed. Unless Sony starts cranking out weather/dust sealed lenses, this may not amount to much. IBIS (In Body Image Stabilization) means all lenses can be handheld 2.5 – 4.5 stops slower than the usual rule of thumb (1/focal length of lens in seconds) which is great for wedding shooters. With a high ISO value of 16,000 what remains to be seen as to what ISO value are images usable without software correction of noise. When I was trying out a Nikon D3s, I found that its ISO 12,800 looked exactly like ISO 3,200 on my Nikon D700 – a 2 stop improvement.
The tiltable LCD panel concerns me as the weak point in the design of an otherwise fine camera. Will it be strong enough to withstand the rigors of pro use? How many times can you move the thing before you snap it off? How many stops of Dynamic Range does this camera have? GPS support is implemented how? These and many other burning questions will have to wait until the 24th. I will keep you posted as more news crops up.
