Question about Trioplan

[wolan]

Hi,
I have the Trioplan 50mm f2.9 and the Primoplan 58mm f1.9 and I am very happy with them.

Do you think the Trioplan 100mm f2.8 can give something more that those lenses do not have? Personally I am not only after the "soap bubbles" but also the pictorial look they can produce. So the question is: Am I getting more of that with the Trioplan 100mm?

Thanks.

Yes, double focal length at a bit faster = double entrance pupil.
So your blur discs are ~double the size when the unshapr parts are at a bit more distance:

This is also interessting for the blurred parts that are no highlights that gives the soap bubbles.

Is it my imagination that prices are not as insane as they have been?

A cosmetically nice looking exakta mount all siver version with optical issues haze and perhaps fungus just topped 500 usd. Seems a little crazy to me but I got my zebra version in mint minus condition with both caps and case for under 100 just at the beginning of the craze.

for me the trioplan 100mm is very unique and my most beloved "art lens". It is not only the bubbles, the trioplan can draw sometimes unbelievable mystique moods depending on handling and light. on the other side there is a lot of glow, flare and low contrast wide open. but you can buy a 135mm Primotar, much cheaper, but nearly the same rendering.
