Canon’s new EF8-15mm f/4L Fisheye USM zoom lens offers photographers the creative possibilities of shooting both circular and full frame images and CPN managed to grab the opportunity to shoot some footage with the lens attached to an EOS 5D Mark II DSLR showing it zooming from a circular fisheye image to a full frame fisheye.
On full frame cameras, such as the EOS 5D Mark II or the EOS-1Ds Mark III, the lens works as both a circular fisheye, where a circular image is projected back to the sensor, and a full frame fisheye where the scene fills the entire sensor.
When the EF8-15mm f/4L Fisheye USM zoom is used with EOS DSLRs with APS-C or APS-H sensors the lens 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 full frame view that’s possible without unsightly edge vignetting. ‘C’ and ‘H’ markings are located next to the lens’ zoom operation ring, indicating the wideangle zoom position where vignette-free shooting is possible with either sensor; thus allowing photographers to achieve optimum results with any EOS body.
