I use this lens all the time. I love a good fisheye. The lens cap is easy to fall off but that may just be my model. Images look sharp and the color comes out nice. Focus is fast.

Worth the money. Sigma's 15mm fisheye stands up to its Canon counterpart and surpasses it in several key respects.

Solid build; quiet focus; and good optics

Third-party lenses are supposed to be priced lower than the brand name; aren't they

i saw this lens in a gray market store, its paint was peeling and it it's front element etched by water damage. i tested it then and still saw some sharpness but everything else was hazy.

sharp; good build(but of course sucky sigma paint and labelling; pretty good control of flaring and ghosting

the build in hood needs some revision; its great and metal protection but how do you mount a filter in the front even with the adapter for the cap

Yes, I would recommend this to a friend

Consistent Output; Durable; Lightweight; Rugged; Sharp Focus; Strong Construction

I very like it, it works good, and thise ddevice is very useful. The pisture turn out goods.I recommend this eyeflesh for everyone.The price is really good.Thank You.

I was debating on getting either a wide angle lens or a fish eye but I am so glad I decided on this as it has more versatility and you can straighten the edges with the Hemi plugin if required.... Love it, it creates unusual perspectives at both weddings and landscapes.

Durable; Easily Interchangeable; Lightweight; Sharp Focus

This lens is fine in itself, but not what I expected so returned.Sigma are a quality make and I have no complaint about their products.

For a product that should be used sparingly for maximum impact, fisheye lenses do not come cheap. The moment I gained more than a passing interest in photography however, I knew I had to have one.

Pruduces stunning; high quality images

Pricey for something you will use rarely

I waited 5 days to get this lens and when i got it i tore it open and hooked it up. i was immediatley stoked as i looked through the veiwfinder. it made me so happy to see such great quality for a low price.

very shapr focusing; smooth focusing; can get super close to the subject and focus well; has a nice fit on the camera (i used canon rebel xt) and overall is soo much fun to use

slightly heavy; and blocks out smaller flashes

Using this with my Sony NEX-3 in manual mode. Was looking for a very wide angle lens to replace the stock 18-50mm kit lense. An excellent lense! Crisp shots, smooth and easy to use.
