The Sigma 18-35mm f/1.8 DC HSM Lens is Very Sharp
« on: July 23, 2013, 02:28:30 PM »

From DXO Mark

The folks at DXOMark have tested the new Sigma 18-35 f/1.8 DC (APS-C) HSM lens and found to be extremely sharp. It turns out that it’s the sharpest APS-C lens that they have ever tested. The performance rivals that of Canon’s 24-70 f/2.8L II lens.


Says DXOMark

“Although it is unlikely a user would buy several full-frame wide-angle lenses specifically for an APS-C format camera, the fact remains that the Sigma 18-35mm f/1.8 DC HSM is an outstanding performer optically.


If we want to be picky, the Sigma lacks image stabilization and the zoom range isn’t as wide as some rivals, but at $799 the lens is remarkable….”

 I'm interested,  but this does nothing for me as I have left the world of crop sensors behind.
Upgrade  path.->means the former was sold for the latter.

dpreview has tested it as well, if you are intersted in a more reputable source than dxomark

EDIT: As pointed out below dpreview partners with dxomark for their lens testing, so... I'm a dummy.

The F-stop is 1.8, the T-stop will probably be in the 2-2.1 neighborhood, possibly 2.2 with that many elements.

DXO measured 1.8

Yes I too was expecting about 2.2

DXOMark said it's 1.8, although that is pretty unusual

Isn't DXO the company that tests DSLR sensors without lenses?

I thought we are not supposed to trust DxO considering they are in the pocket of everyone-not-canon.

Seriously, this is a SWEET lens, perfectly suited for 7D..
