Canon 200-400mm f4L 1.4X lens with pushed to 784mm
With an extra 1.4x telephoto extender attached, the Canon EF 200-400mm f/4L IS USM Extender 1.4X reaches to 784mm with an f8 aperture that was nice for shooting the 2013 supermoon. This photo was shot with Canon's second-generation 1.4x extender, but Canon recommends the third-generation model. I noticed some chromatic aberration issues and somewhat reduced sharpness with my equipment, with a blue fringe at the top of the moon visible in this cropped image.
