Related Questions and Answers

Q: 1. Will this adapter work on The Hasselblad 907x camera?

A: It should mount without issue as the 907X uses the same Hasselblad X-mount.

Q: 2. What will be the change of viewing angle when adapting a Nikon 35 mm full frame lens on the Hasselblad MF camera?

A: The crop factor on the X1D for FF lenses is approximately .8; I've seen calculations as low as .79 and as high as .82. I use several Nikon and Canon lenses on my X1D, and I have found .8 fairly reliable.

Q: 3. Do this adapter alter the original optical quality of the lens?

A: No effect.

Q: 4. Will this adapter accept one of nova flex’s arca-Swiss compatible collars? I would like to use this to mount heavier lenses on a tripod.

A: Unfortunately not. None of the Novoflex collars would fit on the this adapter.

Q: 5. Can you use the lens aperture ring and the blue ring on the adapter in combination? Let's say, set your metering and shooting aperture on the lens, and then use the blue ring to flick it wide open briefly for the sake of precise manual focusing?

A: This will work. Be careful. If you use manual exposure, the viewfinder will probably become too bright to see clearly, because you would be overexposing.If you use aperture priority automatic exposure or auto iso mode, you need to remember to stop down before exposure. You may not see the difference because the camera will quickly adjust the exposure when you go wide open. You will see some fluctuation of intensity in the viewfinder.

Q: 6. When mounting a nikon E lense, is the lens stuck at full open or full closed?

A: E-type of lens cannot be used with this adapter nor can G-type of lens be stopped down with the following adapter.

Q: 7. Can this adapter work for Nikon D lenses?

A: Yes, you may use the Novoflex Nikon F Lens to Hasselblad X-Mount Camera Adapter, B&H # NOHAXNIK, with Nikon D-Type F-mount lenses. As Nikon's D-Type lenses have built-in aperture rings, if you wish to use the aperture ring on your lens, you would leave the built-in aperture ring on the Novoflex lens adapter set to wide open. Conversely, if you wish to use the lens adapter's built-in aperture ring, you would leave the aperture ring on the Nikon D-Type lens set to the lens' widest aperture setting.

Q: 8. There is no aperture setting on my K-mount lenses. How do I control aperture while using this K to RF mount adapter?

A: The blue ring on the adapter is an aperture-control ring. However, you wouldn't be able to precisely select an aperture value.

Q: 9. By mounting the lens to the adapter, does it change the focal length of the original lens? I think it does, but I'm not sure.Thanks for your help.Willy

A: The adapter itself does not cause any magnification, however the camera being an APS-C sized sensor will cause a 1.5x magnification of the lenses you adapt to it. If you have a 50mm lens for instance, it will be equivalent to 75mm on the adapter/camera.

Q: 10. Does this adaptor work with Nikon F lenses that already have their own aperture rings?

A: Yes this will work on Nikon F Mount lenses, the newer G-series as well as the D-series with the manual aperture rings.
