Generally speaking, for a mother recording her children's growth, will you consider T4i to be more suitable for her than 5d mark ii? I understand these are totally different cameras, but I can see that T4i has better auto focus system than 5d mark ii from your review. What's more, the auto focus for the video could be very very useful.
That is really a tough one. I have not used the Canon 5DII, if you can believe that ... I had my 1DsII, and the 20d, 30D, and 40D, so my comparison will be based on those. Plus the Canon T3i.
Sorry for the long pre-amble. I don't want to "oversell" this camera based on my immediate perceptions. New toys are fun!
I was particularly frustrated trying to use the T3i for casual family videos, etc. without autofocus. We were up north on the beach a few weeks ago with the dogs on the beach and the thing was just a PITA. I wound up using my iPhone instead just to capture casual video.
The T4i will go a long way towards filling that gap, with one important exception. The auto exposure is really limited, in that in all auto exposure modes the camera will automatically set was frustrated with the auto exposure mode itself, in that there is no way to control WHAT values are changed in ANY of the auto exposure modes, as far as I have found yet.
For example, the camera will vary shutter speed, aperture, AND ISO. Even in a bright daylight shoot, at 1/100 at f/16, it seems to PREFER to vary the ISO rather than the shutter or aperture. I saw the ISO bounce from 100, to 200, 400, and 800 in a matter of a few seconds when panning across a backlit scene.
It is possible to lock the ISO by holding the <*> key after taking exposure while recording. I have to experiment to be sure, but I think it only stays in effect while you are holding the key.
I haveto run. More in a bit.
