Help identifying LTM lens

[zeshootist]

Hello,

I'm trying to figure out what this (seemingly) 35mm LTM lens in a Edouard Boubat self-portrait is.

Any ideas?

Portrait was taken in 1954, if that helps. Also, I do hope that I am not violating any copyright rules by posting that image, which is ubiquitous on the internet.

Thanks, in advance.

Looks like a cheap Summaron to me.

Could be a 35mm f.2.8 Schneider Xenogon as well. They have the barrel style of the M2 Summaron f/3.5 but a larger front element (as this lens has) than the f/3.5 Summaron which is slightly smaller than a dime.

I think you got it. The way it's catching the light looks just like a non-collapsible 9cm Elmar, which (like the Xenogon) has a dished conical name ring, not flat like a Summaron.

It's a 9cm Elmar from about 1950/51.

Agreed. The lens face looks just like it (I have one) and the compressed perspective in the image supports this guess, too. Plus, almost all of the shorter lenses from that period would have had a focus tab/infinity lock.

Thanks for the responses. At the risk of showcasing my ignorance, I am surprised that that photo was taken with a 90mm lens! The perceived closeness of the subjects to the mirror makes me think that a 90mm lens would have a much narrower field of view. That's why I assumed that it's a 35mm.

However, perhaps the lack of distortion is a clue to greater distance between the subjects and mirror than a 35mm would offer.

Dang, I was almost there 🙄

Being shot in a mirror should have been a clue - it exactly halves the apparent FL (because the distance is halved) so the perspective would be like a 45mm lens, whereas 35mm in a mirror would have looked... strange...

Good to know!
