Q: 5. 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.

Q: 6. What is the maximum aperture of this unit? Are the marks indications of 1/3 stops or do they just serve as a rough guide?

A: The maximum aperture will depend completely on the lens you are using. It offers a built-in clickless iris which allows you to use your lens with some exposure control. There are 9 settings, however they act as a rough guide and how many stops they represent will again depend on the lens.

Q: 7. i got a leica 2.8 90mm elmarit-mand i want to put on my nikon f3 will this do the job ?

A: Yes. It does the job. I have already purchased a similar adapter (Pentax-K to Nikon) and it works fine. You may know you have to work in Manual focus.

Q: 8. Do Canon EF-S lens also fit on this adapter?

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. Does the m39 thread fit a Leica enlarging lens?

A: Fit-wise: the e39 thread should be no problem for using Leica enlarging lens. If remember correctly, enlarging lenses are e39 thread & they should mate with the adapter. Question is how you plan use it on a Nikon body with or without bellow (& which bellow) is another matter.

Q: 10. Will this adapter work with 28 mm f/2.8 ELMARIT-M Asph?

A: Yes, you can use this adapter to mount a Leica 28mm f/2.8 Elmarit lens on a Nikon F mount body.
