I have spent years taking photos of my friends' and family's children and have recently started a small business doing the same for others. I will be doing some family portraits, and some indoor infant photos...but mostly will be following toddlers around outside to try to capture a great moment.
I have the Canon 10D and am researching new lenses. I think that the 70-200 f/2.8l is too large and heavy. I think the 70-200 f/4l is the right lense, but don't know whether I should wait for the new IS to come out in November. I've heard conflicting reports about how helpful it is.
I currently am using an EF 28-105 1:3.5-4.5 that I have from my old film SLR. Obviously, I am having a very difficult time capturing photos even in the shade on a very sunny day. I just haven't felt able to justify such a large purchase until now.
Either lense will be a HUGE improvement over what I have, but want to try to get the best lense for my needs. I don't mind spending the extra on the IS, but don't want to do so if I don't need it. Also, does the IS make it heavier?
Thanks!
