[ACQUIRED] Macro lens for use on bellows

I am looking for a 100+ mm macro lens to use on a bellows. these lenses will have a functioning aperture but no focusing mechanism,

Preferred mount would be Miranda M44x1 mount, but I can also accept T mount (M42 x .75) Pentax Screw mount (M42) or Konica Bayonette nount

Enlarger lens?

Lowell,

I read that enlarger lenses work well on a bellows for macros. There are a bunch to choose from on eBay at not much cost:

enlarger lens, Cameras Photo, enlarging lens. Great deals on eBay!

An m39-m42 adapter shouldn't be hard to come by.

What do you think of this idea? I have no direct knowledge of how one would work.

Dave

PS I'm going to try one as a DIY tilt lens for Pentax-K

interesting idea, I had not thought about it, BUT, the issue will then be one of focal length.

Ideally I would like a 135mm, because the bellows unit I have is set up for a 135mm lens including having a magnification scale printed on it, although I could get by with any length, as long as I can achieve minimum focus.

The problem I can see with an enlarging lens is most of them are probably 50mm or less, because you want the magnification (projected magnification that is)

I will look at it though.

thanks for the idea

I use a 105mm enlarger lens with macro bellows. In my experience the main benefit it has over a normal lens is that, like a proper bellows lens, it is tiny and very light thanks to the lack of any provision for focusing.

I just had a look at E-bay and while there are mostly 50-75mm lenses, I did see a few 100-150mm lenses as well.

I will follow up on this at a few shops I know locally. Makes me feel stupid for trading my darkroom 10 years ago to go digital (considering how little I got for it) but I only had 50 and 24 mm lenses (the 24mm let me project huge images as I was printing 11 x 17 from B&W) with an elnarger that had a relitively short post.

thanks again those who suggeted this.

picked up a really nice 135 mm Schneider-Kreuznach Componar F4.5 at a local store for a good price.
