Q: 1. Does this adapter still allow for the full focusing range from close focus to infinity?

A: Yes, the Voigtlander VM-Z Close Focus Adapter would allow a Nikon Z mount lens to focus to infinity.

Q: 2. What is the amount of extension travel provided by the close focus helicoid? Example: the competing Voigtlander product says it provides 5.5 mm. How many mm does this product allow?

Q: 3. Are these compatible with the Arri SXU-1 (Single Axis Unit)?

A: Yes it is. This can be used with B&H # ARSXU1 as well.

Q: 4. How does this compare to the Fujifilm adapter? What would be the 35mm equivalent of a 50mm noctilux-M

A: The Voigtlander VM-X Close Focus Adapter II for FUJIFILM X and the FUJIFILM M Mount Adapter for X-Mount Cameras are excellent adapters. The FUJIFILM adapter does not have the helicoid element that enables close focus. The Leica Noctilux-M 50mm Lens will have an angle of view of a 75mm lens on a FUJIFILM X camera.

Q: 9. I see some reviews here mentioning that the adapter won't mount correctly on different cameras. Can you confirm if it'll mount correctly on a Panasonic S5 or not?

A: 7artisans Photoelectric Close Focus Adapter for Leica M Lens to Leica L Camera is fully compatible with Panasonic Lumix S5 Mirrorless Camera. The adapter is compatible with all Leica L mount cameras including Leica SL. The click sound when the adapter is mount on Leica cameras is not as loud and clear as in Lumix. We recommend attaching the lens to the adapter and mounting both to the camera. This method will allow you to get a better grip of your lens when attaching them to the camera.

Q: 10. What is the minimum focus distance with this adapter and Voigtlander nokton 50mm f1.0 aspherical?

A: The manufacture does not list the focus distance change with the 7artisans Photoelectric Close Focus Adapter for Leica M Lens to Sony E Camera. But from other customers with lenses like the Voigtlander nokton 50mm f1.0 aspherical it should be able to focus somewhere around 15 inches or so.

[0.05 lb] I find the muscle memory of using these premarked rings is incredibly helpful in my work as a commercial focus puller. This way, on different sets of lenses I still work with essentially the same throw, so there's less time on the job where I need to learn the lens. Highly recommend. 5

[0.7 oz (19 g)] The pre-marked rings for the WCU-4 are great for internalizing the muscle memory of what it feels like to pull from distance A to distance B, regardless of the throw on different lenses. 5

[0.7 oz (19 g)] Mine was lost on a job, needed this in a hurry and B&H did not let me down. It is the ARRI quality that one would expect. No issues. 5

This way, on different sets of lenses I still work with essentially the same throw, so there's less time on the job where I need to learn the lens. I find the 8 ring specifically helpful for music videos, where the artist comes very close to the lens, and also backs up to 12-15 ft all in the same shot. 5
