Wow, that looks huge! I own version 1, and it's fine, but it's not really as sharp as I'd like at 2.8. Looks like they bumped the sharpness a fair bit!
bumped the sharpness where?
just in the center of the frame as far as i can see,and that area aint even covering the crop sensor fine enough ,wide open it´s ok till 4mm (8mm on a 24mm sensor). and the F8 measurment done at 10Lpmm is a joke when they make sensors with resolution with 100Lpmm and above.
i bet it´s just the same old crap (unless u get a good copy), sharp in the middle and blur like hell all around.
i think i´ll just wait for the tamron, if it´s anything like the 17-50 then it´ll be the best choice for both canon and nikon shooters.
by the way, the bokeh seems not that good as the old one.
by the way anyone who dont know how to read `Canon´s ´ MTF . here it is.
Thick black is 10 lp/mm @ maximum aperture (wide open)
Thick blue is 10 lp/mm @ f/8
Thin black is 30 lp/mm @ maximum aperture
Thin blue is 30 lp/mm @ f/8
see, they dont even show you atleast a 50 Lpmm chart, why? it´ll show you how sharp it really is in real world shooting.
