|I've got a very basic and neat enlarger by Ernst Leitz Wetzlar, presumably produced in the 1930s. There is no marking of the model name on it, but a Wetzlar leaflet published in 1930 lets suppose it is a Vitox.
I unscrewed the lens to clean it from dust and found out there is no marking of the brand and name on it or anything else, but numbers of the aperture scale. So, it is a no name Leitz enlarger lens. The aforementioned leaflet speaking on Vitox says just "a lens of 50mm with a relative aperture of 3.5". It looks like in that era branding with names was reserved for parts of higher grade enlargers.
Here is the lens itself:
If my count of bulb reflexions is correct, the lens has 4 elements.
Its iron tube is too long for Sony mount to reach any distance from the object which is situated further than at 20cm. So I could only try some macro shots. And I am impressed by the sharp and clean aspect of the image, as well as by the pop-up. I'd say it is an excellent lens, with a very pleasing rendition, neater than the Soviet tessar-like enlargers.
Due to freelensing here is some edge flare. But even in this case one may note the crisp rendition of details and a very good micro-contrast.
I don't wish to break the enlarger functionality cutting the "extra" metal of the lens' tube. At least before trying to use it for its direct destination.
But I am quite curious about the lens type. I will appreciate much your hints about its name and/or its optic design.
