Canon EF 14mm f/2.8L lenses


  • ultra wide angle rectilinear prime lens
  • neither have front filter threads - only rear drop-in filter holders
  • 2 versions:
    • mark I was initially produced from 1991
    • the later model mark II introduced in late 2007:
      • has more glass with special glasses
      • is larger, heavier
      • focuses a touch closer
      • adds weather sealing
      • improved edge sharpness but still soft wide open
      • different front cap system - now plastic instead of aluminium but designed to lock on thus less likely to fall off, but does not keep dust out and will chafe the lens hood
      • fixes the strong amber ghost images caused by the sun in the original 14mm and replaces them with a much dimmer rainbow laser-beam
      • BUT still unattractive 6 pointed sunstars

compared to the Olympus mZD 7-14mm f/2.8 ultra wide angle zoom lens

  • despite the Olympus lens is a f/2.8 zoom, it is:
    • lighter at 524g instead of 654g
    • a touch longer at 106mm vs 94mm
    • much more affordable at $A1499 compared to $A2659
    • far more versatile as it can zoom to 28mm in full frame terms
    • much sharper wide open edge-to-edge (see charts below)
    • much less CA
    • much less distortion 1.7% compared to 3.7% barrel distortion
    • much less vignetting wide open 1.5EV vs 2.65EV
    • 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 14mm 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 (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
