Dudes, not that I don't appreciate the sharing of some very good knowledge here, but if someone is looking for info on dark and bias libraries, they will not be looking for it under the topic of widest and fastest lens without curvature.
I try to start topics to help myself, with headings that are searchable and helpful for others looking for similar information. A few of my threads have branched off lately.
Again, I appreciate the info and effort guys. I'm just sayin' is all.....
Baz.
