Thanks a lot for your reply.
Your lens looks indeed very good with those smaller screws.

Can you do me one last favor please, just to be sure, and measure the distance between the two red lines (as I drew them on the picture) while the lens is at infinity (at it's shortest, of course).
That should be 148,5 to 150mm right?

One more question I wonder about:
Do you get vignetting with this lens? I ask this because the diameter of the last glass is only 23mm. My aperture will be just behind it and is 26mm in diameter.
But theoretically both those diameters are too small according to me. Hence my question about the vignetting.
