Similar tastes here...
I love both the Primoplan and the Trioplan!
Of course, given my appreciation for vintage optics, I have the original versions of both.
I prefer the Trioplan 100mm to the 50mm version, cause if you want soap bubble bokeh, better go for the big ones
I've used a lot the 100mm N (black barrel) that was available only in Exakta mount. I converted it to PK.
The old version in M42 mount is still without diaphragm leaves. We opened a couple of Meyer lenses with 15 leaves but the shape was different.
I have another chance left... after that I have no more resources. It wouldn't be a disaster cause it's a lens that gives its best wide open.
The Primoplan is one of the worst sealed lenses ever. Most examples have been cleaned, or show some kind of mold/fungus.
Mine cleaned up nicely, and now looks like new. I can't complain.
I am very curious about the new "copies".
As far as I know the optical design is the same, but I guess the optical glass is not identical.
The Trioplan 50mm has a nice touch: a ring that moves the front glass. Other triplets of the past focused the same way. The new Trioplan uses the same trick to affect the correction of the optical design, allowing for a certain degree of softness. At least this is what I understand. Am I right?
