I have acquired quite a few of these old scope cameras and removed the lenses. Not sure how to get the back rings off
to get to smaller 50ish mm threads. A person I linked before suggested cannibalizing some old Vivatar 2X macro
telescoping adapters for the helicoid. Not sure I have access to a way to machine down the thread.
Hey, Plural Waynes,
Although the results are sort of interesting, I have steered clear of lenses that require making machine shop
modifications, custom adapters, etc. It seems to me there is such a vast range of options available without those that I
can skip setting up a shop and learning those skills. 😁

I also have what may be too many lenses in the LensBaby Optic Swap System. When the new Soft Focus II becomes eligible
for my credits, I'll probably get than one too. The magnetic Waterhouse stops are clever, but a real diaphragm in
addition would be really handy.

I have watched a few Simon's utak videos and he speculates that part of the
vintage look comes from the coatings to help get a more dreamy look over modern
coatings. Implying it is more than just the optical formula. I don't have
enough experience to know myself.
Coatings certainly do make a difference. They change contrast, color and flare. And flare can affect sharpness/detail.
I've been recently looking at the Oly 12-200 vs. their 14-150 lenses. In one series, with strong sun in the corner, the
12-200, with ZERO (ZUIKO Extra-low Reflection Optical) Coating, is much sharper/clearer/contrastier than the older
14-150, before the ZERO coated Mk II.
It seems all LensBaby's recent offerings are multicoated. Above, you can see that their simple, one element lenses, as
well as the single element SIMA, are uncoated.
The original LB Soft Focus (one of their earliest and now most sought after lenses) appears to be single coated on front
and back.The new version II has "Broadband multi coated anti-reflective" coatings. I wonder how that will effect rendering.
And how about those non-lens image rendering tools?

This all needs updating with more tools and a second, different subject, but .
