  • sharp in the centre wide open, sharpest at f/4
  • at f/2.0 or f/2.8, it is much sharper than the Canon EF 200mm f/2.8L lenses at f/2.8 and the edges at f/2.0 even matches the Canon EF 200mm f/2.8L lenses at it's peak of f/8
  • at f/4, it is optically similar to the Canon EF 200mm f/2.8L lenses at f/4 although sharper at the edges, but then it is 7x more expensive and almost 3x heavier!
  • edges become softer when used with a 1.4x TC III
  • some long CA wide open but gone by f/2.8
  • almost zero lateral CA, but much more when used with tele-extender 1.4x III
  • spherical aberration well corrected
  • almost zero distortion
  • even with TC, minimal coma even wide open
  • relatively high astigmatism of 7.3% and with TC 7.8%
  • smooth bokeh circles but narrow cat's eye in corners wide open of full frame and odd shaped on APS-C or at f/2.8 on full frame
  • 1.87EV vignetting wide open on full frame and 0.74EV vignetting wide open on APS-C
  • lots of flare if sun hits front of glass
  • AF speed moderate - 1 sec (just over 0.5sec with focus limiter on)
