Shutter durability for D800 is wrong, it is tested to 200,000 cycles too.
Sony A99 can do 8 FPS in crop mode, and 10 FPS in 2X Clear Image Zoom Mode. All with very accurate AF tracking on..
So I vote for Sony A99
Also, A99 probably will always win in AF speed and accuracy. Just like the A77..
Cheers 😀
absolutely i am vote for a99, no doubt.. a99 is the best Full Frame camera for now..
Sony a99 looks amazing….
sony a99 has 3″ tilt way articulated TFT-LCD, D800 and 5D markIII not have that
I also vote for Sony A99.
Canon, nice try, but that price for not much new is ridiculous. Nikon, not even close – I like that Sony sensor you have, but as usual bad overall handling!
Io voto Sony A 99 anche perchè possiedo già la sony a 77…Sony tutta la vita
i will get a99 this time for sure! it is really a beast! either in taking picture and especially rec video(which i need both of them so much)
a china professional man(one fo the ppl that can use a99 before it release) said that a99 is nearly perfect full frame camera he ever used. he said he will choose a99 between this 3 camera! he said canon only good is iso but white balance etc is terrible, and sony a99 combine with carl zeiss is definitely what he want for the picture! he is the one can judge these 3 camera cause he using them all of the time, but he still love this new a99!
some haters will always hate sony by never using them and judge them, the quality of the image taken by sony cameraa99 and also a77 last time in low iso is no.1. i only agree that sony make less lenses which could make some ppl stop by get into sony..
i vote sony A99,,thats amazing,,,,,,canon,nikon NO
D800 has 36MP, this is what i am choose
5D III price drop too quick, don’t like
A99 is useless and less lenses, don’t like
Sony a99 is hard to beat. Loving it so much. Best image quality, hands down.

More megapixels doesn’t mean better quality. Useless? Pretty sure quite a few people would disagree with you. How many different lenses do you need? Sony A99 is an A mount camera. Just on Sony’s website there are 36 lenses and that doesn’t include the E mount lenses you can use with the adapter.
