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

Not so sharp at f1.4, focus problem still remain, chromatic aberration. It is better than canon 50 f1.4 but price is so high.

Sharper than Canon 50 f1.4; nice build

Chromatic aberration; focus problem (font focus with me on Canon 600D); high price

One of best prime lenses in market

"I purchased this lens to take on my this past week. I wanted to have a faster lens for indoor and low light shots than what I currently owned but didn't want to break the bank account either. I was more than pleased with my indoor shots from this lens, as well as my outdoor night shots.

I just love it, my very best fix lens at this focal lenght, to cheap for what you get... needed calibration on D7100, but now it works perfect!!!

built like a tank; very high quality materials; thack sharp; mostly from 1,8..

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 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.

Love this lens. It takes great photos and video, nice bokeh. The focus ring is a bit stiff, but manageable. This is a very nice prime lens for cropped sensor cameras!

The world of camera lenses can be separated into two main groups: zooms and primes. Prime lenses are those which...
