Am contemplating this lens -- and wonder if anyone with first hand experience (not just reading specs and reviews) can comment? Particularly on the 7D or 5D3
I shoot with 7D and 5D3, and am waiting for the 7D2 on order -- I now shoot with the 24-105 and like it but am thinking the 24-70 will fit just fine below the 70-200 f4 L IS - and I shoot outdoors primarily -- sports, wildlife, some scenic. I'd probably use it on both cameras ... not just FF wide.
I read mixed reviews on the 24-105, and find a little bit of mixed in my own brain. The 24-70 would have to be very good upgrade in IQ for me to change -- but am willing to spend it if it gives that IQ improvement.
A personal thought: Some guys seem to think certain lenses are only for either FF or CF, but not both. I find more versatility with a lens on both cameras ... the range increases quite a bit and minimal lose in quality - IMO ...
For example: 24-70 becomes FF 24-70 + CF = 112 .. nice added range, and it then overlaps the 70-200 nicely.
