At CES 2012, Sigma announced that they were going to throw their hat into the Micro Four Thirds (MFT) lens game with their 19mm f2.8 and 30mm F2.8 lenses. These lenses were an inexpensive alternative to those offered by Olympus and Panasonic. The build quality was lacking compared to other MFT lenses as the inner components rattled around in the lens and with a max aperture of F2.8, the lenses are far from being speed demons. Thankfully, most users found the image quality of these lenses greatly outweighed any of the negative qualities. We tested the lenses shortly after they were released and were generally happy with their performance, especially for the price.
So, has Sigma been able to rectify the problems while still keeping the excellent optical quality with these new lenses? Let’s find out.
