I can't believe I'm posting yet another 70-200 or 135L thread but here it goes.. perhaps I have a slightly different take.
So I'm finding my 85L II a little slow focusing and a little short for chasing my toddler around. It seems that a 70-200 would be a good idea. In order to cover indoor shots I'm looking at the 2.8 II but I think that may be a little slow for low-light situations. That leads me to the 135L.... Can those who own the 70-200 2.8 II comment on using it in low light indoors for moving targets?
I could get the 135L for indoors and 70-200 f4 for outdoors but will I be happy with f4 DOF when I'm used to shooting my primes at or close to wide open? Portraits at f4?
My other concern is carrying the weight when travelling. Do people carry this all day out and about with their family?
Of course getting the 70-200 II and 135 may be the eventual solution here....
