Very interesting shots with the Xenon! Is this a coated version? Is the lens recently cleaned? Very nice lens for sure! Can you tell us some more about the lens?


Erik.

Thank you, Erik.
I just cleaned by myself. The Summarit 50/1.5 is also very similar in construction. My Xenon 50/1.5 is 3 ring (1936) Taylor Hobson engraved.

Here a good review about TTH Xenon 5cm/1.5

Thanks a lot, very interesting stuff.

Your Xenon performs beautifully! Was it difficult to clean the lens?

I have an early Summilux. The bloodlines with the Xenon are evident, but the Summilux benefited from the then new lanthanum glass.

Erik.

it was not difficult for me to clean my 50mm Xenon, Summarit, and Summilux v1/v2.
My early Xenon is uncoated. Leitz began with new coating the Xenon and renamed it the Summarit with fluoro coating then they needed to use lanthanum glass to improve the optical performance for early Summilux, and also lanthanum glass (front and rear elements) for Elmar 50mm f2.8 production era 1957-1966.
The lanthanum glass in the Summilux 50mm v1 provides noticeably better imaging performance, especially wide open.

Your works are always excellent, Erik! I like it a lot.
