Canon has announced the EF8-15mm f/4L Fisheye USM L-series lens – the world’s first fisheye zoom lens to offer both circular and full frame images – that provides outstanding image quality, a constant f/4 aperture throughout the zoom range and a robust design.
The zoom lens will replace the EF15mm f/2.8 Fisheye in the Canon lens range and when paired with Canon full frame DSLR bodies, such as the EOS 5D Mark II or the EOS-1Ds Mark III, professional photographers can choose to capture circular or full-frame fisheye images, allowing them to view a scene in a completely new and unique way. This image choice provides enhanced creative flexibility when shooting scenes such as the night sky, where the full 180º horizontal and vertical fields of view (FOV) allow every detail to be captured with incredible clarity in one image.
When used with EOS DSLRs that feature APS-C or APS-H sensors, the EF8-15mm f/4L Fisheye USM produces a more traditional, full frame fisheye view. A zoom-lock mechanism on the lens body allows the range to be limited to the focal length that ensures the best possible full-frame view without unsightly vignetting around the edge. ‘C’ and ‘H’ markings can be found next to the zoom operation ring, indicating the wideangle zoom position where vignette-free shooting is possible with either sensor, allowing photographers to achieve optimum results with any EOS body.

Any Question?
