Could you please tell us why you think He should get the 24-70 2.8? I have been wrestling with the same question and haven't decided. I have a 20D and am looking for a good walkaround lens.
Sorry about that. Well, at first aperture didn't really matter to me in the beginning. After a few low light situations and a few action shots, I figured that I need the the f/2.8. If you are not going to be doing too many action shots are low light shots, then the24mm-105mm f/4 IS L would work jsut fine, but being in the situation I am in now, I would have rather gotten the 24-70 f/2.8.
24mm-70mm avantages ( to me ):
- Faster glass ( 2.8.)
I guess that's it.
24mm-70mm disadvantages ( to me ):
- Weight
- Focal length ( but does not really bother me )
- External Auto Focusing ( i can deal with it )
24mm-105mm advantages ( to me ):
- Focal length
- Weight
- Interal Auto Focus
- Image Stabilization
24mm-105mm disadvantages ( to me ):
- Lowest Aperture ( f/4 )
- Low light situations ( due to aperture ) ( not being abel to focus )
- Not being able to capture motion well
I'm not trying to knock the lens I already have. It has helped me a lot through-out the time I have had it, but I jsut need the faster glass for the type of photography I want to pursue. Hope that helps.
And by saying crop body, I mean everything that isn't a full frame camera. Canon's only "FF" cameras as of right now are the 5D and the EOS 1Ds Mark ll.
