Metabones SPCN-E-BT1 – Contax N to Sony E-mount T Speed Booster ULTRA 0.71x
Electronic focal reducer for using Carl Zeiss Contax N and Contax 645 lenses on APS-C Sony E-mount cameras, with phase-detection autofocus. The 0.71x factor reduces the crop from 1.5x to 1.07x and a Planar T* 1,4/50 becomes an f/1.0 lens.

- Thicker power contacts as on genuine Contax N cameras
- Firmware user-upgradable via the micro USB port
