Q: 5. Most Leica brand M-mount lenses at best have a minimum focus distance (MFD) of 0.7m. This Nokton's MFD is 0.5m. With a digital M body is the rangefinder coupled to support focusing through the optical viewfinder at focus distances between 0.5m and 0.7m?

A: According to our Voigtlander contact, they state on most Leica M-mount cameras, you will need to use the LCD screen to obtain absolute closest focus. While a few cameras such as the Leica MP may allow you to focus a bit closer due to its redesigned finder, it is still recommended to use the LCD screen for the most accurate focus when focusing at the lens' minimum focus distance.

Q: 6. This lens is compatible whit the s1h panasonic

Q: 8. Will this maintain the flange distance for RX C Mount lenses?

Q: 10. Does this adapter allow c-mount lenses to have infinity focus with the Canon EOS-R?

A: All this adapter is doing is making up the flange distance to allow a C-Mount lens to be mounted on an RF-Mount camera. So if the lens you have is a manual focusing lens, you should have the ability to have infinite focus.
