One thing the Sony system lacks is a large assortment of tilt-shift lenses, but this adapter allows you to use existing Canon or Nikon lenses on a Sony body and add shift capabilities. Check out this great video review of the Laowa Magic Shift Converter.
Coming to you from Dustin Abbott, this great review looks at the Laowa Magic Shift Converter. Though designed for the Laowa 12mm f/2.8 Zero-D lens, it can accept any Canon EF or Nikon F mount lens and add shift capabilities. This allows you to do things like photograph buildings and correct converging parallels. While this is an awesome capability to have (and a much cheaper route than a dedicated lens), two drawbacks are the loss of one stop of aperture and the inability to electronically control the aperture, which makes the adapter difficult to use with lenses that don't have a dedicated aperture ring. On the other hand, another major advantage is that the adapter comes with a tripod ring, which in theory allows you to keep the lens perfectly still and shift the camera, creating the best possible panoramas. If you're like many Sony shooters who are using adapted lenses for at least some of their work, it's a very interesting product. Check out the video above for Abbott's full thoughts.
