One Fisheye to Rule Them All!

One Fisheye to Rule Them All!

After spending some quality time with Canon’s newest L-seriesΒ lens, the EF 8-15mm f/4L Fisheye USM, we can safely say it is the undisputed king of the fishes. It’s so versatile that it replaces at least five other lenses: the Sigma 8mm, Peleng’s 8mm, Tokina’s 10-17mm, Canon’s own 15mm and the Zenitar 16mm. It covers the same focal length as all five of these lenses (for the most part) while being sharper across the zoom range, delivering crisp, contrasty images that are to be expected from a lens bearing Canon’s lofty “L” designation. With this lens in your bag, there’s little reason to consider another fisheye lens, regardless of what camera body you are using. Full-Frame and Crop Sensor Bodies If you’re shooting with a full-frame camera like the 5D Mark II, the 8-15mm provides a full circular 180-degree half-hemispherical perspective (see below for examples). If you’re on a crop sensor, you will not get the full-circle effect as it’s simply not wide enough, and at the long end you’ll be at the equivalent of 24mm. This leaves a bit of breathing room for the Sigma 4.5mm which produces full circular images on the crop cameras (the only current fisheye it doesn’t totally replace).Β    What is a Fisheye? The fisheye look is characterized by barrel distortion, especially strong on the edges, that renders straight lines as curves unless they pass through the center of the frame. In some cases the distortion is distracting so many photographers opt to use an ultra-wide rectilinear lens (which lacks the fisheye curvature) such as the Canon 16-35mm or 10-22mmΒ in order to produce a...
