    I'm not sure what a "ring" is in this context. The vast majority of enlargers have threaded lens mounts (usually 39mm but there are a few others such as larger threads for some 150mm and longer focal length lenses).

    I guess there may be un-threaded mounts that need a retaining ring similar to when mounting lenses on large format camera lens panels but I do not think they are at all common - at least, I've not seen one but that is not necessarily a major indicator...

    Given the price of these things these days, I'd go for (and already do own) the f/2.8 50mm El-Nikkor rather than the simpler designed f/4 version.

    Have fun.

    Bob:

    In North America, a large percentage (possibly a majority) of the enlargers out there are Beseler enlargers. If I understand things correctly, Beseler enlargers are much less common in Europe.

    All the Beseler enlargers I have ever worked with have flat boards with a plain hole, and require retaining rings for the lenses.

    IIRC Marko has a Beseler enlarger.

    And the ones that aren't Beselers are mostly Omegas, which can have either kind of mount.

    Taking pictures is easy. Making photographs is hard.
