get the mrk iii with the latest Tech. You will loose some reach, but iq, fps, and 61pts af are great. One less body to carry around.Cortection. IQ (sharpness, DR, e.t.c) is exactly the same between the 5D2 and 5D3, unless you are into shooting above ISO 3500.I say skip the 5D3. Improved AF and FPS alone is not worth it.
"Cortection. IQ (sharpness, DR, e.t.c) is exactly the same between the 5D2 and 5D3" ==> Base on what? Let me guess....DP told you
"unless you are into shooting above ISO 3500" ===> So why do you want mrk II AGAIN???
Have you try mrk III yet? Better AF, faster frame rate, and better ISO(low light)...pls don't tell me these features are NOT worth it.
They certainly are worth it. That's why I have the 5D Mark III. As a third body, however, I am going to get a 5D Mark II just because of the resolution and price. I owned one before and I think I'd rather have that as a true backup body in addition to my 5D Mark III and 1D Mark IV. Where am I going with this? Well, I love the 5D Mark II and 5D Mark III so much, my answer would be to do the trade then save up more money and buy a backup 5D Mark II down the road. Hey, that's just me, haha.
