Reviews and Problems with Sigma 20mm F1.8 EX DG ASPHERICAL RF
Showing 1-3 of 3
Received the wrong lens twice.....
26 February 2013
Summary: Order this beautiful lens one month ago from Amazon, but I received the wrong product. I order the Sigma 20 mn f1.8 EX DF RF and received the one for Canon instead .... I called Amazon right away, went to UPS that same day to did the return, was told that a new one was on his way, three days latter...
Summary: I'm amazed at how inferior this lens is. It looks good. It feels good, and I like the focus clutch mechanism. The specs are great and just what I wanted for my EOS 10D: a wide, fast, fixed focal length lens. I had never bought a third party lens before.
Summary: after reading all the reviews, I decided to pull the trigger and went ahead with purchasing this lens. It was shipped two days later and I immediately performed several test to check sharpness, IQ, and BQ. What can i say, Sigma and their quality control has done it again.
