Sigma 15mm f/2.8 EX DG Diagonal Fisheye Reviews

Bythom reviews the Sigma 15mm f/2.8 EX DG Diagonal Fisheye and writes;
“Overall sharpness is excellent, though I do note a bit of softness in the corners, especially wide open. Depth of field is phenomenal even wide open, which tends to increase the perception of sharpness of the lens. Chromatic aberration is minimal (and not an issue on the digital bodies; a trivial issue on the 35mm bodies).”

Sigma 15mm f/2.8 EX DG Diagonal Fisheye User Reviews

It’s actually a very good lens! | Rating: ★★★★☆
“if you use it with an APS-C sensor digital slr, you won’t see a whole lot of distortion. It’s no different from the Canon brand fisheye on a camera like that. But, if you use it with film, or with a larger sensor size camera, full-frame if possible, it’s really quite a beautiful, sharp, and very fish-eyed lens. On a Canon 5D it performed really well for me.” – by Laurel

Use your brain and the right camera | Rating: ★★★★☆
“This is an excellent lens that does exactly what it’s supposed to do. Optically, it’s also excellent.. This lens is very good close to the optical quality of the Canon fisheye — I’ve used both. But the game here is the intentional distortion on full frame. A standard wide-angle of this focal length does not cover 180, but something around 112 degrees — on full frame.. The images are high quality and a reasonably skilled photographer can produce excellent work with this lens without relyin entirely on fisheye cliches. “ – by In the Middle of the Road

Incredible Lens | Rating: ★★★★★
“This lens is really incredible… The quality has always been great with Sigma and this lens is as great as Sigma’s reputation… If you plan to use this lens with a Digital Camera, do not forget that there is a x1.2 coefficient (this lens is a 15mm but used on a Digital Camera, it turns into a 18 or 20mm). If you want the effect of a fisheye (180degrees), consider buying a shorter lens (8mm). “ – by Nicolas Suc

Great lens! | Rating: ★★★★★
“I love this lens, its wonderful and there’s absolutely nothing wrong with it. If you want the distortion to be seen in “full force”, you should use a camera with a 1.0x crop factor (full frame or 35mm film). You wont go wrong with this one. I like it better than the Canon one. It’s tack sharp, great colors and contrast. “ – by L. Santos

A GREAT Lens……PERIOD! | Rating: ★★★★★
“Don’t get me wrong, this lens is FUN!! I’ve never enjoyed landscapes, portraits, artistic shots more than I have when I am using my 15MM Fish. For the Casual user, high end amateur, or for the seasoned professional, this lens is an inexpensive TOOL each of us should have to round out our lens bag.” – by R. W. Strauss

read reviews and know your camera | Rating: ★★★★★
“I have two full frame cameras that this lens does exactly what it is suppose to do at with excellent sharpness and color contrast. Don’t use it much, but when it is needed there are no other lens that will match it for it’s speed f2.8 and price. On an AP-C camera, e.g. 1.6 sensor, it is the equivalent of a 24 mm on my full frame.” – by M. Barrera

Great lens – zero vignetting | Rating: ★★★★★
“The short story: its a great lens that has lots to offer for anyone who like wide angle shots. Colors and flare resistence is tops. Centre sharpness is very good even wide open, while corners tend to be soft and suffer CA unless it is stopped down. as long as you shoot “rounded” objects such as people, a fisheye often works better than a traditional wide lens like the Canon 14L..” – by Maiaibing

Exceeded my expectations | Rating: ★★★★☆
“There are limited uses for a fisheye, but when you hit the right shot for it, this one works great. Chromatic aberration is very low and lower than I have seen in other lenses like this one. The autofocus works well, but with a fisheye, focus is rarely an issue anyway. With the f2.8 speed and ultra wide angle I usually have this lens stopped down and then the DOF is something like 18″ to infinity.” – by Arjen Sundman
