Overall, the new Sigma 30mm ƒ/1.4 DC Art is a fantastic APS-C fast prime lens that delivers great image quality with nice, sharp images, low vignetting and only slight barrel distortion. While CA is bit more pronounced versus its predecessor, overall it's a very minor issue.

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).

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

Sharpness towards edges of the frame could be better; CA at maximum aperture; Focusing issues with review samples

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

Captures nice images
