Canon EF 300mm f/2.8L USM lens

introduction

  • the pro level weathersealed 300mm f/2.8 lens is perhaps one of the most popular sports lenses for the professional, particularly when shooting field sports under lights from the boundary
  • the original version of this AF lens released by Canon in 1987 was integral to Canon dominating the pro sports market when they finally released a pro AF SLR in 1989, and then for the next decade or two thanks to its fast AF compared to the competition in the 1980's, and Nikon did not catch up to the AF speed with such a lens until 1996.
  • in 1999, an image stabilised version replaced the original version, changing the rear filter size to 52mm, removed the MF speed options, is closer focus to 2.5m and made slightly lighter while tripod mount made removable
  • in 2011, the lens was again upgraded with improved IS, curved diaphragm blades, close focus further improved to 2m, made 8% lighter again and adds a Power Focus mode for video and new mode 3 IS but tripod mount no longer removable
  • these are big, heavy and very expensive lenses designed for use on a monopod NOT hand held!
