I'm loving all these old-lens images. Here's my contribution. Elmar 90mm f4 on MM1.

MM2 + Taylor&Hobson Summarit 5cm. at f.5.6

 

Downstairs, I've rarely seen more clean and in-focus images than yours, and suspect it might have something to do with your Taylor&Hobson Summarit. Could you please explain what a Taylor&Hobson Summarit is, and where to get one? I can't see anything relevant to Summarits on their website.

The history is entangled.

Zeiss develops Planar lens (1890-ish)

TT&H (Taylor, Taylor & Hobson) designer H. W. Lee revises the Planar formula to be less symmetrical, and have some optical improvements - result is the Opic lens (1920)

A.W. Tronnier of Schneider-Kreuznach uses aspects of the Opic to develop a 50mm f/2 Xenon (1922-24) to match the Ernemann/Ermanox 80mm f/2 for 645 format.

Zeiss introduces the 50mm f/1.5 Sonnar. (1932) - Xenon f/2 languishes - revived in the 1950s.

Leitz contracts with Schneider to develop an f/1.5 version of the Xenon to compete with the Sonnar (1936). Also called a Xenon, originally.

Post WW2, the Leitz-Xenon is renamed the Summarit.

Some Xenon/Summarits may be engraved with the TT&H patent, but it is not a pure TT&H design or product as such. It's possible TT&H built some Xenons once the supply from Germany was cut off during WW2. WW2 "broke" a lot of patents, making designs freely available.

In any case, a 50 f/1.5 Xenon/Summarit is always the same optics. A Schneider design, with historical links to TT&H.

T&H 50mm Summarit at 5.6 - but with a little help from Helicon Focus.  Taking a series of six shots shifting the focus-ring  from closest to furthest element allows me to use window light without noise.  The  T&H behaves badly stopped down and long exposures are noisy.

The best lenses for low-light still-life are the leica-Rs because the focus rings have a long “thow” and allow for very precise steps.
