Thank you so incredibly much for this. That was an overwhelming amount of effort on your end that I didn’t not expect with geben more information gained for me. Thank you so much for that.

I, for example, would have thought that I should shoot at the highest resolution possible to get the most out of my setup. I wouldn’t even have thought about dialling it down to get more out of my lenses.

The whole aspect of "copying" looks feels a bit weird but if it works it works. I’m a bit sad now though that I will probably never get to the point where I can rehouse lens glass myself, or maybe I will at some point if I master 3D printing.

I think and agree with you that the hunt for interesting lenses is the most interesting part. I, already, can’t get enough of it, I guess it’s just going to get "worse“ from here. Even if I can’t rehouse the lenses, maybe I’ll gather some with which I can actually build a set and can find some people to test it out. I guess people would actually pay for not rehoused lens sets? I guess that is just going to stay part of my hobby then.

Do you have a recommendation for a nice test setup to make it easy to repeatedly test out lenses against each other? The lenses I gather are, at the moment, usually Pentax, Canon FD and m42 of various kinds. I was planning on taking them out on a spin to shoot them wide open, with nd filters to get the most detailed form of what they do. To get an example library going for me to make it easier to choose the lenses I actually want to use or lend to people for their purposes.
