Great glass, great buy!

This 15mm f/2.8 Sigma lens performed great right out of the box with my Canon 350D. I take astro photographs of the night sky and it grabbed a bunch of sky with very minimal horizon bend. Nice piece of equipment.

Better than I expected


from Palos Verdes Peninsula, CA  -  Semi-pro Photographer

Traded a bunch of rarely used lenses for this Fisheye. Have Canon 24-70 f/2.8 L and 70-200 f/2.8 II L, considered Canon 16-35, but too much overlap. The image quality is fantastic. I can't really imagine much better results with any lens ... At a reasonable cost.

Great Diagonal Fisheye


from Catonsville, MD  -  Photo Enthusiast

I had wanted a fisheye for some time, but I didn't want one of the fisheyes that was a circle inside a black frame. This diagonal fisheye is what I settled on. I read reviews of the Canon fisheye (which is more expensive, and an f.4), and there is negligible difference, especially considering the price and maximum aperture. Plus, this is a FUN lens, not a work lens! The lens is not "cheap" in terms of price, and definitely not in construction. It's well made, and has a solid feel. There are many auto-focus points that are very usable on this lens, and it locks-in very quickly. The manual focus is easy to use (good grips, smooth action), and has focal ranges marked clearly on the lens body. Reviews cover it, and the lens doesn't hide it - there is some noise when focusing. If you are used to a USM, it is louder than that. If you have ever used the Canon 50mm f1.8 lens, it sounds similar to that during auto-focus.


Very fun lens


from Olympia, Wa  -  Photo Enthusiast

I looked into this lens when the Nikon 16mm was out of stock. Reviews looked good and the $300 savings was also appealing. I took it on a photo workshop and was not disappointed. The lens is sharp and has very little flare. I was able to shoot straight towards the sun for "sun star" effects for some great shots. Shooting old trucks was awesome with this lens. All in all, a very fun, lightweight addition to my kit. I'm very glad it bought it.

I really like this lens


from Portland, Maine  -  Photography Student

Fisheye lens are, in my opinion, meant for creative pursuits. At least that's what I use mine for. This is a very good lens. I have a couple of Sigma lens and they haven't let me down yet. Add this to that list.


Great alternative to Nikon 16mm Fisheye!


from Harrisonburg, VA  -  Semi-pro Photographer

Up until now I have been a Nikon purist - I wanted everything to be pure Nikon. I bought this lens because it was $300 cheaper than the Nikon 16mm Fisheye and it is every bit as good! I have not been disappointed yet!


Fun lens for unusual shots


from St Louis  -  Semi-pro Photographer

Great for the unusual perspective.

Fast focus and sharp!


from Baldwin, NY  -  Pro Photographer

If you havent used a fish eye before get used to the field of view! I do have pics with my feet in them, lol. I went with the Sigma over the canon to save cash. good choice in that I use this lens occasionally. it performs well for the money if you dont have L glass money.

A little loud but out performs the Canon


from worldwide  -  Semi-pro Photographer

After using the 10mm Sigma Fisheye on my 7D, I needed a lens that would be compatible with my full frame 5D. The 15mm Canon has known issues, those of which the Sigma lack. Although it's a little loud when autofocusing, it's fast and sharp. Even wide open, aberrations are barely present, when compared to the now defunct Canon 15mm. Worth the money and great for video.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
SALMAN A  Reviewed tests for the Canon and the Sigma. Picked this for better build quality and AF and I think I made the right decision. Image quality is absolutely superb and close focus is good too. Very happy with it.
Patrick S  I have a Canon T2i Rebel body. Will I get the full "fisheye" effect and will the auto-focus work with my camera? Thanks!
GARY D  The Rebel T2i uses the APS-C sized sensor, which means the Sigma 15mm f2.8 EX DG on your camera would have the equivalent focal length of 24mm - still technically wide angle. This Sigma lens provides a 180 degree field of view on a full frame sensor camera. On the APS-C sensor, cropping would cut that field of view but I don't know exactly how much. While I've not personally seen this combination, I would think that you'd lose some of the fisheye effect. Autofocus should work normally, though.
Shopper  does this lens include cups too?
SALMAN A  Cups? I assume caps. It has a very nice metal friction cap that fits by sliding over the fixed metal hood. You cannot mount a filter in front as there is no filter thread and it has a 180 degree FOV. There is obviously a raer lens cap.
