Q: 5. 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: 6. Will this adapter work on my a6000? Also, how quick is the autofocus on this adapter?

Q: 8. 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: 9. Will this work on the 80D?

A: Yes this would work perfectly on your Canon 80D.

Q: 10. Can I use the adapter for Sony Full-frame E mount ?

A: You can, but you will loose auto focus capability. However, this product is inferior, I would not recommend it to anyone. It is poorly constructed. Its internal screws became loose and it fell apart within the first few days of usage. I had to glue it together to finish my safari photo shoot!
