Re: PrinzGalaxy (Spiratone) 400mm F/6.3 Lens test

I have the spiratone version of the lens and I like it a lot. I haven't used it much, but it performed better than the 500mm mirror lens I was using (Kalimar). I think it sharpens up a little at f8 and above, but haven't done a lot of testing with it. It was an old lens my dad had laying around.

Here is a sample picture, I don't recall the aperture setting:
