price of this lense is pretty awesome already, and i got an open-box for even cheaper $. very happy with it. large aperture makes need for flash is not always necessary. perfect for pix of kid around the house. a bit on the heavy end, but that is just an indication of quality lenses.

solid feel; good price

none so far

This lens must weight as much as my Nikon D40 and is excellent for taking candid photos of my 16mo old son. This is the best investment I could have made for my Nikon D40. Since is has HSM, it works with the Nikon D40 which needs to have the motor in the lens.

Huge optics

None

This is a very nice lens for the price. Heaps cheaper than a nikon comparable product, nice and sturdy and produces nice bokeh at open aperture.

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

Great prime! This has been on my 7D at least 90% of the time since I've purchased it. Abes has new the version with Sigma's new finish which has been working great, although I did have to set MA to -3.

Fast / accurate auto-focus; Nice Bokeh; Rugged; Strong Construction

Chromatic aberration

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

Image and build quality

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 not used the lens too much yet, but seems pretty god in operation. Focus & quality appear good, & the large aperture is good for low light photography. The physical size is considerably more than the kit zoom supplied with the camera, so it loses something of it's "compact" convenience.

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!

One of best prime lenses in market
