The lens, however, still maintains a fisheye 'look' as objects will appear increasingly stretched and enlarged the closer they are to the edge of the frame. This is a rectilinear lens, which means the geometry of straight objects, such as walls or the sides of buildings, will appear less curved despite the extremely wide focal length of this lens. If your camera(s) has/have a APS-C or APS-H sized sensor, this probably isn't the lens for you. The Canon 15mm f/2.8 Fisheye lens is a bit of a boutique lens, but can come in very handy in certain circumstances if you own a camera with a full-frame sensor. Small minimum focus distance, sharp, relatively fast to focus Compared to the prices of lenses Canon is selling now, this lens is a steal. If you can find a used or refurbished one, I recommend giving it a try. When I went to full frame, I really missed my Canon 10-22, but this lens makes up for that. I have played with correcting the lines, and nearly always find the original results more natural and pleasing to the eye than corrected ones with straight lines. The lines do curve strongly, but not ridiculously. They do call it a fish eye, although I find it to be more of a hybrid between fish eye and ultra wide angle lens. ![]() I find them to be easily correctable with software though. Wide open, you get some pretty strong red chromatic aberrations in the corners. Not, not as sharp as the center of course, but perfectly usable. Even wide open, my copy is surprisingly sharp in the corners. It should be fine unless you plan on abusing it. The focus motor is on the louder side, but then again, the distance it has to travel is so minute that it really doesn't matter, it only "buzzes" for a fraction of a second until something is in focus again.īuild quality is good, nothing to brag about, but not like a cheap kit lens either. The lens cap is of a odd design, it would have been nice if it locked in place somehow, but it does the job. Compared to all the other L lenses, this lens is actually small. I bought this lens refurbished directly from Canon. ![]() Thoroughly recommend this lens if you like full frame fisheyes, and much, much better value than the current Canon 8-15mm zoom.Ĭompact, fair price, lightweigh, sharp, built in metal lenshood The AF is old and not USM - but who cares really? The large cap tends to fall off. The Sigma has very unreliable AF (unfortunately a common trait with Sigma), and I used to resort to Live View focusing with that one - not a big deal with a fisheye of course due to the great depth of field, but it is very nice to have the quick AF with the Canon. Sharper across the image area at full aperture and better AF. This is a better lens than the Sigma 15mm, which is pretty good itself. Excellent image quality even at f2.8 - may need a tweek in sharpness or clarity on LR to match your other 35-50mm primes, but very good for a fisheye.
