10 out of 10 points and recommendedInsane resolution, great images, beats all my other lenses (even L-lenses)Manual focusing almost impossible
I've tried a number of primes and L-zooms, but none of them has been able to outresolve this bad boy.reviewed August 12th, 2009 (purchased for $70)
This is the only lens I've tested that manages to outresolve the 450D-sensor and give perfect per-pixel-sharpness at f/3.2 or higher.
At f/1.8 it's a bit soft - especially around the edges. But for me, that softness generally isn't a bad thing. Instead it softens up the DOF so you don't get that hard in-focus-out-of-focus-line, and for some reason images taken with this optic at f/1.8 tend to become realy esthetically pleasing.
Example of f/1.8 (to show the beautiful soft DOF):
Example of f/3.2 (to show the sharpness, click on "Original bild" just below the picture and start pixel peeping):
