You can find reviews on the sigma lenses on lenstip; I believe they have the 19 and 30 for micro 4/3 mount; I could not find them for nex mount. They do make some rather negative comments about the nex-7 anti-alias filter making it very difficult to test lenses.

There biggeest complaint with the sigma is astigmatism and a touch of ca.

Hi wasn't aware of it till now, just had a look at it thanks. Shame they do not provide samples on each lens.
