Special Effects Lenses

Mount and type of distortion separate these three. The Canon EF 8-15mm f/4 L is the only zoom here, covering a range of fisheye framings in one lens, and it fits EF bodies. The Sigma 15mm F1.4 DG DN Art is a diagonal fisheye in Sony E and by far the fastest of the trio — night work and astro. The Canon RF-S 3.9mm Dual Fisheye carries two optics on a single body, for paired capture. €1,194 to €1,969.
