SLR Gear, an offshoot website of the Imaging Resource, one of the web's most-trusted resources for all things digital photography, has just posted an in-depth review of the new Sima 30 f2.8 DN Art, which is designed strictly for mirrorless camera users
So, how does it do in practice? Short answer: rather well.
Optically, the lens is very good. In terms of sharpness, the lens is good right from the get-go at f2.8 and ges even better in the corners at f4. According to SLR Gear, diffraction limiting starts to set in at f11, which means that sharpness decreases from there. As for distortion, it's virtually nil here. Vignetting? It's there wide open, but disappears stopped down to f5.6. Chromatic aberration? It's there, but very well controlled as compared to the old version of this lens.
Mechanically, the lens uses Sigma's HSM AF drive technology, which results in silent, virtually instantaneous AF. The lens also has full-time manual focus capability, too. As for construction quality, the lens is very well built thanks to all-metal construction.
If there is one nitpick on this lens, it is the fact that Sigma didn't make the lens inner focusing.
Overall conclusion? Very positive, especially considering the $200 price.
