Olympus mZD 7-14mm f/2.8 PRO lens

introduction

  • officially announced May 2015 with release date for June 2015

  • silent AF
  • MF ring has the same pull back for analog control rather than just focus by wire mode as with some of their other lenses including the Olympus mZD 12-40mm f/2.8 Pro weatherproof lens
  • 'L-Fn' button which can be customized with 17 possible functions
  • 105.8mm long x 78.9mm diam and 534g

filter holders

compared to the Olympus ZD 7-14mm f/4 Super High Grade Four Thirds lens

  • 1 stop faster than the Four Thirds lens – that is – it lets in TWICE as much light thereby allowing lower ISO to be used in low light, but even with this extra stop of aperture it is a welcome compact size
  • shorter: 105.8mm long instead of 120mm
  • smaller: 78.9mm diameter instead of 87mm
  • much lighter: 534g instead of 780g
  • close focus reduced to 20cm and a working distance of 7.5cm (the close focus of the Four Thirds lens was 25cm from sensor)
  • new ZERO nanocoating to further reduce flare
  • new manual focus clutch to switch into “analog” manual focus mode with distance scale instead of the default focus by wire mechanism
  • new L-Fn button which can be assigned to any of 17 functions on the Olympus OM-D cameras
  • AF is now silent and optimised for CDAF live view and videos
  • new optical design appears to have much more distortion and curvature of field than the Four Thirds lens
  • perhaps best of all is it is around HALF the price at $US1299

compared to the Canon EF 14mm f/2.8 L II prime lens

  • despite the Olympus lens is a f/2.8 zoom, it is:
    • lighter at 524g instead of 654g
    • 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
    • 7 blades not 6 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 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

    • shorter at 106mm vs 112mm
    • closer focus at 20cm instead of 28cm
    • more affordable at $A1499 compared to $A1899

    • 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

    • 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, however, the Canon 16-35mm f/4 lens is a far better lens (although for static scenes, the new Olympus cameras can shoot 40mp HiRes shots with less moire on a tripod)

compared to the Canon EF 16-35mm f/4L pro zoom lens

  • despite the Olympus lens can go wider to 14mm, it is:
    • lighter at 524g instead of 600g
    • similar length at 106mm vs 103mm
    • closer focus at 20cm instead of 28cm
    • more affordable at $A1499 compared to $A
    • far more versatile as it can zoom out to 14mm in full frame terms
    • perhaps similar sharpness wide open edge-to-edge (see charts below)
    • perhaps similar CA
    • much less distortion at widest zoom 1.7% compared to 4.3% wavy barrel distortion!!
    • much less vignetting wide open 1.5EV vs 2EV
    • both have 7 blades
    • both have reasonably nice star shapes for astrophotographic landscapes of the Milky Way
    • has eye detection autofocus for portraits
    • has fast, silent AF for movies
  • why would anyone buy the Canon 16-35mm f/4lens then?
    • this is perhaps the best wide angle zoom for Canon full frame cameras and if you own a Canon full frame, this is the one to get, but there are no real advantages over the 7-14mm and of course it does not go as wide

compared to the Nikon AF-S 14-28mm f/2.8G pro zoom lens

  • the Nikon AF-S 14-28mm f/2.8G lens is generally regarded as the best ultra-wide zoom lens for full frame, so much so, that even many Canon users go to the trouble of using it (although now they have the Canon 16-35mm f/4L IS lens which is superb)
  • let's see how the Olympus lens compares, it is:
    • much lighter at 524g instead of 970g
    • much shorter at 106mm vs 132mm
    • focuses closer 20cm vs 28cm
    • more affordable at $A1499 compared to $A2797
    • sharper wide open edge-to-edge (see charts below)
    • marginally less CA
    • much less distortion at widest zoom 1.7% compared to 7.4% barrel distortion!!
    • much less vignetting wide open 1.5EV vs 2EV
    • 7 blades not 9 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 Nikon 14-24mm lens then?
    • if you already have a Nikon full frame dSLR with 35mp and you shoot landscapes or studio fashion 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, although a little less dynamic range)
    • 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 to the corner sharpness of the Olympus lens, so that argument generally won't hold much
    • you may get better sun stars with its 9 blades
    • otherwise see your mental health therapist
