Venus Optics has announced the Laowa 0.7x Focal Reducer for its 24mm f/14 2x Macro Probe lens that reduces the crop factor when using it on APS-C, Super35, or Micro Four Thirds, which helps retain the lens's perspective.
Zhong Yi Optics has announced the Mitakon Turbo Adapter II for Nikon Z-mount, which takes M42, Canon EF, or Nikon F-mount full-frame lenses and adapts them for use on Nikon Z APS-C cameras and widens the angle of view to more closely mimic their focal length on full-frame bodies.
After many weeks of rumors and leaks, Canon has officially unveiled its first RF-Mount Cinema EOS camera: the 4K EOS C70. In addition, the company also debuted a new EF-to-RF speedbooster, which allows users to take full advantage of full-frame EF lenses on the C70's Super 35mm sensor.
When Canon officially entered the full-frame mirrorless space with the EOS R, they were praised for releasing not one, not two, but three different RF-mount lens adapters. But it seems that was just the beginning...
If you read the title and thought "huh?" you're not the only one. Hearing that an adapter can actually make your lenses faster and wider sounds a bit like photography science fiction, but it's true and it's getting some serious attention online -- it's Metabones' new Speed Booster.
