Sigma 8mm f/3.5 EX DG Circular Fisheye Reviews

Photodo reviews the Sigma 8mm f/3.5 EX DG Circular Fisheye and writes;
“For those needing this type of lens, for example when using software to create panoramics or for those involved in the scientific measurement of angles, where the output from this lens is quantifiable, this lens is an excellent tool. For those who just want to experiment with the unusual perspective of a 180° field of view, or even the somewhat reduced field if using the lens on a cropped sensor, then this lens is a high class example.”

Shutterbug reviews the Sigma 8mm f/3.5 EX DG Circular Fisheye and writes;
“For the most part I had fun with the lens and accepted the distortion as part of the experience. You don’t shoot fisheye only for a wide angle of view—you go in knowing that edges will bend and vanishing points will get weird. If you want a super-wide point of view without distortion get into stitching.”

Ephotozine reviews the Sigma 8mm f/3.5 EX DG Circular Fisheye and writes;
“Contrast is very good, with the 10-90% rise staying well below one pixel throughout. Chromatic aberrations are also exceptionally well controlled with no readings even approaching a level of concern. Flare, although present to an extent when strong light sources were included in the frame (fairly un-avoidable considering the type of lens) is restricted to the area of the image it is included in and no ghosting is apparent showing strong control of internal reflections.”

User Opinions

Sigma 8mm f/3.5 EX DG Circular Fisheye User Reviews

I’m very happy with this | Rating: ★★★★★
“Sharp, good flare control, lots of fun. The previous reviewer says something about the AF being slow– which, while true, is only half the story. You’re almost always going to be focusing at or near infinity, so it’s actually very rare to have to wait. Because this lens has such wide depth of field, I actually usually keep it on manual focus and leave it near infinity. “ – by D. B. Smith

Fabulous Wide View | Rating: ★★★★★
“I think this is a great lens for expanding your view of the surrounding environment. This Sigma Lens works flawlessly in conjunction with my Canon Rebel, I am looking forward to the time I use it with my soon to be purchased Canon mark 3 which has a larger sensor. The focus is sharp, the color true, and the price was right.” – by Michael Steindel

Fantastic Specialty lens | Rating: ★★★★★
“I have this lens for about 2 months now and find it to be indespensible. The 180 degree field of view with the fisheye effect allows me to be very creative with my photography. A great investment in my lens collection.” – by Joseph Sudano

Outstanding for 360 panorama work | Rating: ★★★★★
“I also bought this lens to use with my XTi (400d) on my 360 panorama rig. Its fantastic for not only that purpose, but lots of creative work as well. It is a great addition to my lens collection and I know a few pros using it for pano work as well. “ – by PrOxY

Fun | Rating: ★★★★★
“Very fun lens! Good color, sharp, great distortion. I have a Canon Rebel XTi and with the 1.6x crop i needed something with a lot of distortion. The vignetting can be pretty annoying because you have to edit every photo but it’s no big deal. This is a good lens and I normally dislike Sigma. “ – by D. Cooper

Sigma 8mm Circular Fisheye is Top Quality! | Rating: ★★★★★
“This Sigma lens is like a working piece of art. The build quality is high, the images are bright and sharp with excellent color saturation. I use mine to shoot full-screen 360 by 180 panoramas and the results are breathtaking! The best part is that this lens costs 1/3 to 1/4 of what the Canon 8mm lens costs. It’s an awesome deal, no matter what way you look at it. The Sigma 8mm is definitely a professional grade lens.” – by Uncle Rocco

Excellent Choice for my Canon 40D | Rating: ★★★★★
“I own an excellent selection Canon “L” lenses. But I was ready to try to fisheye. After extensive research, I decided to give the Sigma 8mm f/3.5 EX DG Circular Fisheye a try. I’m glad I did. This lens feels good, it’s small (compared to my “L” lenses), it focuses fast and quiet. The photos it takes are outstanding. I have even stated using the Fisheye-Hemi Photoshop plug-in to manipulate the images and “straighten” them out a bit.” – by D. Burbank

Great lens | Rating: ★★★★☆
“Great lens, but has blue chromatic aberration on the edges of the circle, easily fixable in photoshop. I loved it for my Canon Rebel xti (cropped cirlcle due to cenversion factor), now I love it even more for my Canon 5D Mark II ( full circular fisheye ).” – by Dominika Gardocka

Fun lens! | Rating: ★★★★★
“It is super close-focusing (you can nearly touch the subject with the front element!), and VERY sharp.. The lens itself is QUITE small, but solidly built as are most Sigma “EX” lenses. I often throw this lens into the bag on any outing as it can provide some creative outlet not possible with other lenses, and get me to think outside the box.” – by R. Lanthier

8mm rules on full frame! | Rating: ★★★★★
“This is fun unlike anything else. Full frame at 8mm + 180 degree view angle – sweeeet! I heard the newer f3.5 DG is far better in IQ department. But my fisheye is for fun really, the distortion and the covering all/missing none effect, so pxiel level sharpness is not the most important thing for me here.” – by Luving it

Wicked fun. | Rating: ★★★★☆
“This lens is just wicked fun. It’s small and light enough that you can just keep it in your bag to pull out any time. It seems to make skies just pop even more than a circular polarizer does on a standard lens. Very few lenses will give you a cool picture just by pointing it up at the sky. This one will. For framing shots, just a few steps back and you can get grand vistas. Get right on top of something and it looks like the whole world is a fishbowl around your subject.” – by E. Winemiller
