Related Questions and Answers

Q: 1. Does the adapter utilize any glass between the camera and lens?

A: No, the adapter does not utilize the any glass between the camera and lens.

Q: 2. Will this fit Nikon rangefinder lenses as well?

A: Whether related to patents, differing initial engineering decisions, or by mistake, the rangefinder coupling of the Nikon-S lens mount was slightly different than that of the Contax-RF. The result is that the wide angle Nikon-S lenses, because of their wider depth of field, can interchange between the two types of bodies, but the standard and telephoto lenses cannot. The the Kipon adapter will work with your wider Nikon lenses but not anything above 50mm.

Q: 3. Does this electronically connect with pins so you have full control of all the camera functions?

A: Unfortunately, this adapter is completely manual. It works best with Nikon F mount lenses that have a manual aperture ring.

Q: 4. Will autofocus work with this?

A: The KIPON Lens Mount Adapter for Nikon F-Mount Lens to Canon RF-Mount Camera does not support autofocus or any camera to lens communication. Everything has to be set manually.

Q: 5. Is this compatible with the Dzofilm Catta 18-35 Zoom as well?

A: Yes, the DZOFilm Lens Mount Bayonet (Canon RF) would work with the DZOfilm Catta 18-35 mm Zoom as well.

Q: 6. Is the opening in this T-adapter an M42 or an M48 (ie, how wide is it)? Have some specialize equipment that uses M48 which I'd like to use if possible (assuming I get the EOS Ra).

A: This adapter is M42.

Q: 7. is that possible to control aperture of Nikon pc-e lenses?

A: No, the blue ring on the Novoflex Nikon F Lens to Canon RF-Mount Camera Adapter cannot control the aperture on any Nikon F-mount lenses under the E line. The Nikon E line of lenses have an electromagnetic diaphragm, which can only be controlled through electronic communication in the camera.

Q: 8. Do you focus with the focusing on the telescope I'm assuming?

A: Yes focusing is done on the telescope.

Q: 9. what does the control ring do? does it open and close the iris?

A: The ring on the KIPON Macro Lens Mount Adapter with Helicoid for Canon EF-Mount Lens to Canon RF-Mount Camera is not a control ring; instead, it is a helicoid ring that you may turn to elongate the lens adapter, thereby increasing your lens' minimum focus distance. When the ring is set to its standard position, you will be able to focus to infinity. However, upon turning the ring, you will lose infinity focus, but it will allow you to focus closer to your subject and increase its magnification.

Q: 10. Does the helicoid allow this adapter to function like a gariable extension tube? If so, how much extension is available?

A: Yes it is essentially a variable extension tube and it will extend up to about 5mm.
