The canon r100 lens mountfrom canon r100 lens mountallows a Nikon F-mount lens to be used with a Canon EF-M mount camera. It is designed to support focusing to infinity, and is constructed from brass and an aluminum alloy along with a stainless-steel lens mounting ring to provide a durable, yet lightweight camera-to-lens connection.

This adapter does not support electronic communication between an attached camera and lens. For Nikon F-mount, G-type lenses that lack a means to adjust apertures on the lens body itself, the Pro Lens Mount Adapter provides an aperture-control ring that couples with a compatible lens's aperture mechanism so that adjustments to brightness, as well as depth-of-field, can be made. That adapter aperture-ring can also be used alternatingly with a non-G type, Nikon F-mount lens's own aperture-control ring.

Q: 1. I am about to put my Rokinon Cine Primes on my Bolex H16 and shoot some Tri-X 200 asa. Has anyone tried this? Is there a calculation for setting exposure to adjust for using the c mount to eos ef Canon adapter? If no one responds I will be happy to post my results.

A: The iris on this adapter is not needed for use with manual lenses like the Rokinons. You just use the manual iris on the Rokinon lens while leaving the iris of the adapter at its widest opening. The adapters iris is meant to compensate for loss of the iris control of a Canon EOS EF lens. Now in the digital world you could just set this up and see the effect of the adapter iris immediately on screen. However, since you are shooting film, we suggest doing what a professional would do before principal photography and that would be to shoot an exposure test. (there is no available exposure calculation chart for this adapter.) Line up a shot of a person holding a grey card plus a notation of what the f/stop is that you have determined by using a light meter. You can use a clapperboard or a clipboard to display the card and the f stop. (Do yourself a further favor and have it held steady in the frame held by a grip stand.) I would shoot at a variety of f/stops so that I would know what was happening if I was to shoot at those f/stops. As you can see, we strongly suggest sacrificing a roll of film this way so that you know you are getting correct exposure once you start shooting for real.

A: Sorry no, a EF-S lens will not work with this adapter. I suspect it is because the rear glass element of the lens will hit the aperture blades.

Q: 9. Are there caps on this? I am concerned about dust. Without caps my concern is you have a little cup pointing up catching dust, you put the lens on and flip it, dust falls onto rear of lens, put lens back on camera, dust in camera.

A: there are no provided caps....you could use a camera body cap or use two lenses so that it's always covered ...just a note--the camera body caps don't fit very tight...at least mine don't...

Q: 10. Would this work on a beaulieu 5008 super 8? Have a canon EF 70-300mm ultrasonic. Please answer back

A: From our research that vintage camera does have a C-Mount. However how well any adapter and modern lens will work on a Vintage piece of gear is something you would need to test out to see the results. Since this is an EF to C-Mount adapter it should work, but we are not aware of any specific testing done between the two.
