You and I are on the same page on almost all this. Entirely so.
Why didn't you say all this in your original post? All the angst you've caused, oh my.
You have well and truly buttered your own bread on this one. Now you'll have to lie on it.
To respectfully disagree on some of some of your points, by comparison to an inbuilt camera meter, how is a Gossen Lunasix around your neck not "clutter"?
Are you saying Pentaxes didn't have motor drives? Huh, we will have to disagree on that one.
Also that Pentaxes are "minimal" because they don't (again, so you say) don't take a motor drive, while Nikons aren't because they do?
By this logic, the fact that your Nikon F can take an FTN finder means it isn't really "minimal", doesn't it?
I do agree with the rest of your post about using "minimal" cameras. Which is what I try to do, with Nikkormats and Rollei TLRs. Also now and then a Voigtlander Perkeo II and a Kodak Retina IIc - overlooking the Perkeo and the Rolleis which are MF and not really relevant to this thread, you can't really get more minimal than those.
All respectfully submitted for your critical consideration.
For all this kit-kit and yap-yap, this is a fun thread. Please carry on!
