Canon L EF 8-15mm f/4L Fisheye USM
Offering a unique dual-purpose design, this L-series lens shifts from a full-frame circular fisheye at 8mm to a rectangular 180° diagonal fisheye at 15mm. Its optical construction uses two ultra-low dispersion elements and Sub Wavelength coatings to suppress chromatic aberrations and flare, all within a weather-sealed, 540g body. This lens is best for architectural and creative photographers who need extreme, distortion-controlled perspectives on a full-frame Canon EF mount.
