I got to test out this setup today.
Canon 1DX with the 24-70f2.8L II
I've used the version 1 many times before and it was a good lens.
After reading so much about the ver2..i was expecting super results from it.
Firstly, it's smaller and lighter than ver 1 and it's very noticeable.
The zoom ring is also much stiffer (maybe because it's brand new?)
I like the new lock on the zoom...i wish all canons had that...
The material is almost identical to the macro L..very plastic.
However, one thing i was disappointed with was the focus speed...it' DEFINITELY no where near as fast as a prime lens. It's also not as fast as the 70-200f2.8 IMO.
It's not slow by any means but on a 1DX, i was expecting instant focus but it's not much faster than the old one..almost can't feel the difference actually. sharpness wise, i believe there are enough images online for you to judge yourself since i'm not too bothered about sharpness.
Bottom line, it is better than version 1 but to me, i won't pay the difference in price...and the 82mm...that's a bummer
