A. Schacht Travegar R 100mm/3.3 - Opinions?

I am looking at a Schacht 100mm/3.3 Travegar R. According to the specs I have seen it has 3 lenses in 3 groups (so a Cooke triplet?) and this one has a 16 bladed aperture. Other than that I have not been able to find very much on it. Has anyone used one? Opinions?

Regards, C.

I have such a lens. you're right. lens has 3 lenses in 3 groups and 16 bladed aperture. lens is made reliably. all parts are working properly. my lens is a Praktina lens. I had to make an adapter to the nex. lens does not have an MC. the lens on the open diaphragm may seem soft. if you want to get bubbles like a trioplan, then I failed.

It's a lovely lens, I've had mine for a long time and used it on APSC cameras and my A7II full frame with excellent results. Obviously it is a lens of its time, and probably uncoated. But it is sharp, and any lack of contrast is soon corrected with a bit of processing.

I copied this from somewhere - probably this forum.
"The 100mm is a triplet, I guess it's very close to the Isco Cassarit.It's rather uncommon, and like other triplets under 135mm is not very cheap these days. A true pity, cause I like very much Schacht lenses, because of the way they are built (one of the most elegant barrel engineering, with beautiful DoF scale).I also own the 6-elements f/3.5 version, that was highly valued in its time and sold by Leica dealers in LTM version. My curiosity about the last generation of Schacht lenses came from a sort of academic interest. Those optics were designed by (or released under the supervision of) one of the best optical designers ever: Dr. Bertele, the father of the Sonnar."

These are all taken with a Pentax K10 APSC and they are processed, but they do show what can be achieved from this delightful lens.

Thank you both. The colors remind me of what I am seeing from my Schacht 135mm 3.5. I would perhaps describe the color as neutral, not overstated. I like what I am seeing Smile

Very nice images indeed, and that's a double sword really. At first I reacted like: "This lens really renders nicely, do I want this?", but then I figured it could be much more about the skilled use of the tool. Seems like a nice little lens though, not without character as expected considering the optical design and the manufacturer as well.

There is a 105mm F/3.5 Travegar, a triplet usually found with short mount used in bellows. I think they should perform more or less the same?
