comment What does “R” mean in Fujifilm's XF Fujinon lens names?
Very odd. I will has Fuji. I would have imagined something more along the line of rear-focus or reduced flange distance.

comment Should I put UV filter to protect the lens even if I put a lens hood?
[Cont'd] As soon as you have any light source in your frame it can happen. I have seen it personally dozens of times when some of my photography students keep their UV filters on (or sometimes do not know they have one) and I take it off in the middle of the shoot. The improvement is truly dramatic and is immediately visible.

Those diagrams may describe the measured effect of UV filters but they only tell part of the story. The most common degradation resulting from UV filters is much more serious than the attenuation of certain wave-lengths and will completely ruin a photo even with expensive multi-coated and super-multi-coated filters. See this for example.

comment Is there a correspondence between Tilt-Angle and the angle of the Focus-Plane?
Interesting. So, in your diagram, u' would be measured along a line halfway between the two grey lines? It would clear things if you could label the diagram with ψ, u' and θ in the right places.

comment Why shave a cropped-frame fisheye lens instead of buying a full-frame one?
That is a full-frame fisheye (180-degree FOV diagonally) but the Sigma 8mm is fully circular (180-degree FOV in any direction), so both extremes are available without modifications. So that's left is the $150, it could be.

Didn't know about that one but I published a similar post 6 years ago: blog.neocamera.com/?p=32
