Is the $1400 SIGMA 135mm F1.8 Sharp at F1.8? Let’s See in This Quick Test. Download three sample RAW files right here http://froknowsphoto.com/sigma-135-quick-test/
I just got this SIGMA 135 F1.8 in the mail courtesy of SIGMA. We have a few weeks to do our review before we have to send it back.
I did a quick portrait test at F1.8 with Todd to see how tack it is wide open. From the quick test, the focus looks right on even wide open, the contrast is nice and the lens feels great.
