Light hits this lens element from a far greater number of angles than a rectilinear lens captures. There are wide angle lenses out there that are not technically fisheye lenses, but they can only reach a certain focal length before they, too, begin to capture a little distortion.įisheye lenses achieve their unique effect by utilizing a much larger, fatter, more overtly convex front lens element. The shorter the focal length, the wider the angle, and the further distorted the edges of the image will be. To be more specific about a fisheye lens, these are the lenses with wide fields of view and a clear amount of barrel distortion, making the video and images captured through them appear evenly curved all around the sides. If a fisheye lens also carried with it the memory issue, well, your photographs would have to self-destruct after five months like a dossier from Mission Impossible. Still, through the eyes of a fish, after five months, everything looks new again.įisheye lenses carry with them the wide field of view with which most fish would see. It is, however, a myth, as modern research claims fish can retain information and training for up to five months. I remember growing up hearing that goldfish, in particular, had about a 30-second memory span. There's a long-standing myth out there that fish don't have especially good memories. ![]() One new company that did make the cut is Altura, and the Altura Photo 8mm f/3.0 Professional is right up there with the likes of Rokinon's manual focus stills lenses, with a fast aperture and solid build quality. Some new wide angle lenses have hit the market in recent years from third-party manufacturers, like Irix and Neewer, but these either perform too poorly or direct their light into rectilinear images, which by definition aren't fisheye no matter their focal length. All the selections on our previous list have remained, largely due to the fact they represent either the best that a given system has to offer or they boast a particularly unusual feature, like the body cap pancake design of the Olympus 9mm f/8.0. Given the fact that the fisheye lens isn't among the most sought after tools in modern photography, the big companies like Nikon and Canon haven't introduced new models to the market in some time. If a wide field of view is a must for you, but you aren’t necessarily hung up on the fisheye effect, then you might also be interested in checking out our list of wide angle lenses. ![]() ![]() It’s designed for use with full-frame DSLRs, so you shouldn’t need to worry about it cropping in on your images, and versions are available for five major camera companies. It certainly isn’t an option that’s going to dethrone any of our top three, but, since there’s a good chance that a lot of our users are considering this purchase for infrequent use, we thought it was worth including as a wallet-friendly alternative for those who aren’t ready to cough up for a more expensive choice. We did, however, beef up our roster by one model with the new inclusion of the Sigma EX DG 15mm f/2.8. It was another slow year for fans of fisheye glass, and for the second year running we retained all of our existing options for this category.
