That's a good question!

I know it is a projection lens, though not sure if it was for motion picture or still. It would be interesting to have the model type of projector used for this lens. The seller stated that it was made prior to 1950.

Pretty good. I had thought it is 14mm. It is actually a 14cm lens.

Thank you. As it is written on the name ring.

#2 is impressive. A lovely natural level of sharpness for wildlife, to my eyes at least. Nice unobtrusive bokeh too. And I like the transition to oof. And I'm familiar with all that's in #1, and the colours look bang on. In fact, the more I look, the more I want this lens. Like 1 .

The sharp areas are smoothed out by the overlapping of aberrations. I am totally fine with that, and it reminds me of some fast 50s in the sense. Although, the foreground bokeh can be a little messy with certain colors.

The result is wonderful! BTW i know that helicoid can be buy on internet, but how about the adapter that connect the helicoid? Did you made it on your own?

Thanks! Was it possibly the Jena TK 35 model film projector?

Yes, not the most ergonomic outfit though. I have seen more practical implementations using the shell of a gutted lens.

Thank you. Best to have the lens in hand to measure what you need for the build up.

Taken with about 55mm of helical extension on this setup. MFD was less than 2 meters.

The results are very pleasant, for the combination of sharpness and mild character. The first shot is especially attractive, with its contrast of colours. Thanks for sharing!
