Fotodiox Contax / Yashica to Canon EOS Adapter with Focus Confirmation Chip

Fotodiox  Contax/Yashica (C/Y, CY) Lens to Canon EOS Lens Mount Adapter

with Dandelion Focus Confirmation Chip

SKU: CY-EF-FC10 (CY-EOS-FC10)

This Fotodiox lens mount adapter allows Contax / Yashica (CY, RTS) Lens to fit on Canon EOS camera body. 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 with EOS body. Infinity focusing is guaranteed. The added microchip (or dandelion chip) enables the focusing confirmation function with EOS Digital bodies, which helps the the photographer to manually focus even in dark situations.

Compatible Cameras

• Canon 1d, 1ds, Mark II, IV, 5D, 5D Mark II, 7D, 10D, 20D, 30D, 40D, 50D, Rebel xt, xti, xs, xsi, t1i, T2i, 300D, 350D, 400D, 450D, 500D, 550D, 1000D

Incompatible Lenses

Although this adapter will fit any lens with a C/Y (Contax/Yashica) mount on it; some lenses are not recomended to be used with the Canon 5D series as that camera has a larger than normal mirror which may hit the rear of the lens during use. Reportedly the following adapted Contax lenses are not compatible with the EOS 5D series:

• 18mm f/4
• 85mm f/1.2
• 135mm f/2

There have been conflicting reports on the Contax 28mm f/2.8, perhaps suggesting unreported lens variations. Lens mount variations have been reported on the 28mm f/2.8 and the 35-70mm lenses. These lenses may require about 1mm to be filed from the end of the brass locking latch, before the lenses will lock on the adapter. Take note that if you do this modification, the adapter may or may not lock on other Contax lenses.
