This is a fantastic lens! Since I have had it it hasn't came off my body!

I wanted a crop sensor lens that was close to a 50 mm full sensor. I read a lot of reviews, then settled on this lens. I'm a newbie and and still working on my ideal stills but this lens rocks for video

Durable; Easily Interchangeable; Excellent Field Of View; Great for Video; Lightweight; Love The Sharpness

Slight Auto Focus Issues

The Sigma 30mm f/1.4 DC HSM A is a wide-aperture standard lens for APS-C cameras

F/1.4 maximum aperture; Excellent MTF results; Full-time MF option; Near-silent AF; Metal mounting flange

Significant barrel distortion; Some colour fringing; No image stabilisation

Despite the naming similarity, there is a world of difference between Sigma's 35mm f/1.4 and its 30mm f/1.4 (reviewed here). Whereas the former is a full-frame lens, the latter is APS-C only; whereas the former has a petal-shape lens hood, the latter's is cylindrical; whereas the former offers...

Have had this lens for about a week now and it produces some amazing images on my Canon 60D.

Image and build quality

The Sigma 30mm F1.4 DC HSM "Art" is a fast prime lens designed exclusively for APS-C DSLRs; it's of particular interest to us because its "normal" field of view corresponds roughly to that of a 50mm lens on a film camera.

Fast F1.4 maximum aperture; Convenient focal length on APS-C; Beautiful bokeh; Excellent center sharpness; Compact and easy to hold; Minimal vignetting at F2 and above; Resistant to flare and ghosting; 4-year warranty (USA; Very affordable

More distortion that we'd like to see in a premium prime; Purple fringing near edges/corners; Low contrast wide-open; Somewhat heavy given its size; Average corner sharpness; Not weather-sealed; Sluggish autofocus

Purchase use. Very good from F/2.2. Front focus 1.4-2.0. After 2.2 have litle back focus. From f4 focus is perfect. Work very well in life view with Canon 60D. Mutch better than Canon 50/1.8.Very happy.

The 30mm f/1.4 DC HSM Art is another solid entry in Sigma's prestige lens line-not the finest glass the company has to offer, but a marked improvement over the older (if cheaper) 30mm f/1.4.

Last year I made the switch to full frame and parked Sigma's 50mm F1.4 Art lens on my 5Diii. I thought full frame was the most amazing thing, and I could never go back. Then I started doing a little bit of video work, so I dusted off my SL1 to use as camera 2.
