ZY Optics Lens Turbo II (Mark 2) - Pentax K to Sony E mount

The ZY Optics Lens Turbo Mark 2 (Pentax > Sony E mount) is the new updated version of the Mitakon Lens Turbo speed booster adapters. The ZY Optics Lens turbo provides 0.726x magnification and increase aperture by 1 f-stop, whilst offering Impressive quality and superb value, the new improved lens coating offering better sharpness over the older models. The Lens Turbos allow the attachment of Pentax PK K mount lenses onto Sony E-Mount bodies such as the NEX and ILCE series bodies. They are focal reducers, focusing the light of a larger sensor lens onto smaller cropped sensors, resulting in a brighter image / aperture gain of one f-stop and a wider angle of view (0.72x crop factor), working like an inverse teleconverter.

Please Note: Although the lens will fit physically, other functions like autofocus which are dependent on communication between the camera body and the camera lens will no longer function using the Lens Turbo adapters / speed boosters. You will need to manually focus and to set exposures manually or meter in aperture priority mode.

For most Sony NEX and ILCE cameras you will need to select and set "release without lens” to ENABLE / ON in the cameras menu to enable the camera to fire without recognising a lens. The Sony cameras are capable of shooting in A or M modes and using manual focusing. To assist manual focusing some models also feature Focus Peaking, which can be switched on in the cameras menu if the camera supports this feature.
