  • the very average image quality Canon EF 16-35mm f/2.8L version II was introduced in 2007 this has been updated in Dec 2016 with a mark III version which is sharper wide open at 16mm and with less CA and the 9 blades give much better sunstars but otherwise fairly similar at other focal lengths
  • compared to the 16-135mm f/2.8L II lens, the newer Canon EF 16-35mm f/4 L IS is:
    • sharper edge-to-edge
    • less expensive
    • adds image image stabiliser so you can shoot at hand-held at 1/2 to 1/4 second


Canon EF 16-35mm f/2.8L III USM

  • announced Dec 2016
  • Fully weather-sealed construction
  • Sub-wavelength Coatings (SWC) and Air Sphere Coatings (ASC) to eliminate lens flare and ghosting
  • Two large-diameter double-surface GMo lenses plus a ground aspherical lens to help decrease distortion, curvature of field and astigmatism
  • Two UD lenses help to reduce chromatic aberration
  • 9 rounded blades not 7
  • 790g (up from 635g in mark II)
  • 128 x 89mm
  • EW-88D lens hood
  • $US2199


    • sharpness wide open highest at 16mm (much better than mark II) but 2.6EV vignetting in corners and 2.7% x 0.9% barrel distortion, but lateral CA well controlled and much better than the version II lens
    • at 28-35mm need f/5.6 for maximal sharpness and at these focal lengths, the distortion is pincushion, and the sharpness is only minimally better that the mark II lens
    • distortion similar to mark II lens but simple and easily correctable

16-35mm f/2.8L II compared to the Olympus mZD 7-14mm f/2.8 zoom lens

  • despite the Olympus lens is a f/2.8 zoom down to 14mm not 16mm, it is:
    • lighter at 524g instead of 640g
    • shorter at 106mm vs 112mm
    • more affordable at $A1499 compared to $A1899
    • far more versatile as it can zoom out to 14mm in full frame terms
    • focuses closer at 20cm instead of 28cm
    • much sharper wide open edge-to-edge (see charts below)
    • much less CA
    • much less distortion at widest zoom 1.7% compared to 7.4% barrel distortion!!
    • much less vignetting wide open 1.5EV vs 1.9EV
    • both have 7 blades
    • has much nicer star shapes for astrophotographic landscapes of the Milky Way as it has less coma aberration
    • has image stabiliser of 5 stops allowing hand held shots at 1-2 seconds courtesy of the Olympus cameras (the Canon has no IS)
    • has eye detection autofocus for portraits
    • has fast, silent AF for movies
  • why would anyone buy the Canon 16-35mm f/2.8 lens then?
    • if you already have a Canon full frame dSLR with 50mp and you shoot landscapes on a tripod at f/8 then it may have a use as it can take filters although you should be buying the much better f/4 lens (although for static scenes, the new Olympus cameras can shoot 40mp HiRes shots with less moire on a tripod)
    • one could argue you can get 2 stops better ISO on full frame, but with this lens you need to stop it down 2 stops to get close the the sharpness of the Olympus lens, so that argument generally won't hold much
    • otherwise see your mental health therapist
