my 1st post here, so be gentle!
I'm coming from a Nikon DX nad in the process of upgrading to FF and today I was around during an important Canon event so I had the chance to try briefly the 5D3.
As all my lenses are DX and I won't use them in a nikon full frame body, I'd sell them anyway. So I'm evaluating both the "sides" of the fence.
5D3: very impressed for the quality of the body and the speed and reliability of the AF, the silent shutter mode, the high ISO performance. A bit less from the dynamic range and color rendition (even in raw) but I guess I cannot have everything.
Besides the normal differences in ergonomics I'm still perplex at some strange behaviours of the camera so here are the detailed questions (as Canon noob!
1) Is it normal that the AF point in the viewfinder blink red when in focus and then disappear?
2) camera in manual mode but with Auto-ISO on; it's not possible to have an exposure compensation, is it? I used the camera only for half an hour but I was not able to get it. I.e. : f/8 1/125 iso1600, I put +1 to exp comp and I still read: f/8 1/125 iso1600 . Why?
3) Auto-ISO on and I can choose the slowest shutter speed and the max ISO value from the menu system, and it's ok but then, if I have a zoom on, the suggested shutter speed doesn't change to reflect the actual focal value of the zoom and the camera gives me always the same pair of aperture and time, doesn't it? why?
4) Metering and AF: does the camera have a face-recognition AF mode (not
in Live view but normal shooting mode)? So that it tries to track and catch the human faces when AF is in Auto?
5) And does the camera link the AF data to the metering, changing the exposure according to the choosen in-focus subject (face)? I didn't get any evidence of that in my short test this afternoon.
Thanks very much, I really need to understand how it works!
