After reading all of the reviews about distortions on this lens compared to the

older version which I just sold I was very hesitant ordering version II.

But with Amazon return policy I could not go wrong.

Got this lens and I was very surprised.

Distortions are not as bad as in reviews. In the worst case

if straight lines are very close to the edge and the edge is just few feet from the lens

I get barrel distortion. Easily fixed and at the most I lose 1mm. Probably less.

In real life it almost never happens. This lens is also very sharp wide open maybe even slightly sharper than Canon 16-35mm F2.8

at F4.

On the other hand corner sharpness is almost 2 stops better than previous version of this lens.

Not only that but on previous version corners were smudged unless stopped down to at least F8 or more.

On the new version corners are just less sharp but still very acceptable wide open.

Combine that with much less vignetting (at least one stop less) and we got a winner here.

I use this lens on Canon 5D MK2.

I would give it 4.5 stars if I could.
