Perfect lens if it focused properly out of the box. Lens has a little front focus on my Rebel t3i. Sent to Sigma for calibration with camera body still waiting for it to return. Otherwise good quality lens.

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 ($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.

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 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

I may complete a full Sigma 30mm f/1.4 DC HSM Art Lens review in the future, but please use the standardized test results currently available for this lens.

I love this lens! It's been my go-to for my Sony a6000. I think it's a pretty good lens in terms of quality and cost for someone who's starting out with photography. The bokeh is pretty nice. I've gotten a lot of compliments on the shots I've taken with this lens. So happy I decided to get it!

I've had this lens for about two weeks. Not a lot of time to develope an opinion but just some initial observations. It's going to be best as a portrait lens, the focus is sharp and accurate when the subject is close (say 2-12 feet).
