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...

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

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 Sigma 30mm F1.4 DC HSM Art ($499) is a standard-angle prime lens for APS-C cameras. It's one of the rare SLR lenses in this focal range that's dedicated to that sensor format, and the only one with an f/1.4 aperture. Nikon, Sony, and Pentax all offer more affordable options with maximum apertures that range from f/1.8 to f/2.4, but the Sigma 30mm is available as a faster option for all of those mounts, and is also available in versions for Canon and Sigma SLRs. The lens is just a little soft when shot wide open, which prevents it from getting top marks, but it's a solid option for APS-C shooters. If you're not willing to compromise on image quality in this focal length range, another Sigma lens is the way to go. Our Editors' Choice Sigma 35mm F1.4 DG HSM ($679.95 at Amazon) is a lot bigger and heavier, but it's deadly sharp at f/1.4 and works with both APS-C and full-frame cameras. The 30mm is part of Sigma's Art series, which is the category that the company is using for al...

The Sigma 30mm F1.4 DC HSM is a solid option for APS-C photographers who want a standard-angle prime with an f/1.4 aperture, but it's a little pricey compared with f/1.8 lenses.

Compact; Opens to f/1.4; Very sharp when stopped down; 0.3-meter close focus; Sturdy build

Some edge softness at wide apertures; Modest barrel distortion; Lacks optical stabilization; Pricey

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.
