More Mirrors for Mirrorless, C-Mount Looms

Tokina stepped up to the mirror lens plate with an entry of their own, the 300mm f/6.3 mirror lens for m4/3. The new lens will be shown at CP+, which starts on February 9th. I've added the known particulars of this new lens to the Lens Database section.

Meanwhile, the much forgotten C-mount is about to make a march on mirrorless. C-mount is a basic screw mount that provided lenses for industrial camera purposes and a number of smallish formats such as 16mm movie film cameras and a number of video security cameras. A number of us GH2 users found various C-mount lenses that provided full video frame coverage that were very useful, so it's not unknown to convert C-mount to mirrorless. 

Now one of the larger producers of such lenses is going to provide a converter and a number of their lenses for various mirrorless mounts. Kowa (a supplier to Pentax, amongst others) will announce at CP+ next week the following lenses:

  • m4/3 mount: 12mm f/2, 16mm f/2, 25mm f/2, 35mm f/2, and 50mm f/2
  • Nikon 1 mount: 16mm f/1.4
  • Pentax Q mount: 5mm f/1.8, 8mm f/1.4, 12mm f/1.8, 16mm f/1.4 and f/1.8, plus 25mm f/1.4 and f/1.8

These are all manual focus lenses, and Kowa promises there will be more to come. However, some vignetting is likely with some of the camera/lens combinations.
