Canon EF 8-15mm f/4 L USM Fisheye

Great At What It Does This lens provides a type of image I won't use often but which will be very handy at some times. Shooting with a full-frame camera means I'll get good panoramic shots without stitching from this lens and the occasional fish-eye shot with which to entertain clients. The lens has Canon's typical quality and ease of operation. Color anomalies are minimal and not noticed.

Great lens! I am using this lens on my Sony A7IV with an adapter for Canon EF/EF-S mount to Sony E Mount camera. Lens works great! Produces very sharp images. It came in perfect condition with original box. Excited to capture some fun shots with this lens!

Great for Underwater Photography Bought this lens for my Nauticam Sony a6500 underwater housing. I'm using it with a N120 4.33 fisheye port attached to a N85 to N120 50mm adapter, so I can use it with the Sony APS-C system. In APS-C one can set a limiter switch on the to keep the lens operating between 10-15mm to avoid the wider angle vignetting that will happen on APS-C since it's a full frame, full circle fisheye lens. Th is a very sharp lens and works well with mini-domes being sharp in the corners. It was a bit expensive to go this route, but the combination opens up all kinds of possibilities with other lens, besides the Canon 10-18. It focus well, even in low light, including constant focus in video mode using a Metabones Mark IV adapter using the latest firmware v63.
