Had the same issue with my Fujinon 25mm F/0.85. Fully screwed in, infinite was abouy halfway through the lens’ focus range. Ended up wrapping some sewing thread around the bottom of the threads to “tune” it to infinite, about a millimeter. Works great now.
I suspect the infinite point is out a bit to account for the waterproofing O ring on the ENVIS lens. Mine seems to be spaced out a bit when seated properly on my Mod3c. So many be that it?
I write a little about something else. Narrow lens adjustment range. When make adapter it is necessary to maintain a distance to the sensor.
As for mod3. My NV uses a different body. This is Katod Inc. Distance to sensor ~ 10.5 mm, hole diameter 28 mm min. The battery compartment is upside down. With this body, I have more free choice. For example, 2 inch nose for paracorr through M42 with an open hole of 28 mm (photo).
