the digital picture sigma 17-50 OS review

Has any one seen this review. http://www.thedigitalp​icture.com …C-OS-HSM-Lens-Review.aspx. Whats with corner crops with the trees, the scene shifts with every lens used, even the two Tamrons are completly different, and why does he not show a full sixed image so we can see where the crops came from in relation to the entire scence (I know he says they are top left but how big a top left corner is that). Above all it flies in the face of what a lot of users on here say about the 17-50 OS.

Photozone has sample photo images which you can see full size and zoom in to see @ 100%. Corners look fine to me.

Agreed...fantastic lens at price savings when compared to the more expensive Canon...glad I went for the Sigma

Summary from the review: "If you don't need sharp corners (except at f/11) and you don't need every shot focused perfectly, the Sigma 17-50mm f/2.8 EX DC OS HSM Lens is a great lens for the price. This is a good upgrade-to-the-kit-lens option."

LOL! What the heck?! Another "favorable" review of a 3rd party lens from TDP

I'm going to trust myself on this one

Yeah, that made me chuckle too

I like the lens so far, but to be honest, the corner performance at wider FL is not stellar. For example, for a large group portrait, using 28mm and f/5.0, faces near the edge were obviously more blurred, and needed selective sharpening. The same for my landscape shots at 17mm - with the apertures I usually use (f/8-f/10), edges are obviously soft.

I can't compare this to my previous lens (Tamron), because the Tamron had serious AF problems, and even at the center short FL shots were way off.
