Canon EF 200mm f/2.8L lenses


  • Canon EF 200mm f/2.8L II released in 1996 to update the version I lens and replaced the built-in hood with a snap on hood but otherwise they are similar lenses
  • a favourite amongst astrophotographers on APS-C cameras
  • mark II is overdue for a replacement to address lack of weathersealing, no rounded aperture blades, and is less sharp than a 70-200mm zoom but at least it is less than half the price and weight
  • 1/7th the price of the Canon EF 200mm f/2L lens and much more compact and light


  • 200mm f/2.8 full frame
  • 8 non-rounded blades
  • 9 elements in 2 groups inc. 2x UD elements
  • 72mm filter
  • internal focus with rear focusing to correct aberrations
  • close focus 1.5m giving 1:5 magnification
  • USM AF
  • 83 x 136 mm
  • 765 g
  • lens hood
  • not weathersealed


    • 0.76% pincushion distortion
    • 0.9EV vignetting
    • sharp wide open but sharpest at f/5.6
    • minimal lat CA of 0.5px
    • nice bokeh although a tad nervous at critical focus transition zones and out-of-focus circles become cat's eyes in corners due to vignetting
    • medium long. CA
    • excellent coma - this is why astrophotographers love it!
    • mild astigmatism 7.6%
    • not quite as sharp as the Canon EF 70-200 mm f/2.8L IS USM II but much lighter, smaller, cheaper and better vignetting, flare and slightly better CA and distortion
    • bokeh can be nervous at transition zones and can give cat's eye oval shapes
