Fotodiox Pro Lens Mount Adapter, Pentax K (PK) Lens to Sony Alpha A-Mount Cameras such as Sony A100, A200, A230, A290 and A30

Product Description If you have a SLR or DSLR camera and other maker/mount lenses, the Fotodiox Mount Adapters allow you to use your lenses on the film/digital camera body. Sharing lenses has some distinct advantages. Adapting larger format lens to smaller format sensors provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. This Fotodiox lens mount adapter is made with high standard precision. This Adapter has a built-in 1.4x Multi-Coated Focus Correction lens to adjust for infinity focus. The glass element can be removed for macro photography. This adapter allows Pentax K (PK) Lenses to fit on a Sony Alpha (also Minolta AF, A-type, Maxxum or Dynax) camera body. Adapter caps are included to protect the focusing element when not in use. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode. Infinity focusing is guaranteed.
