70mm side mounted is a mount but it is best ignored. There is a version a little over 60mm while the soviet ones are different yet again. At the back the diameter is usually smaller and differs with focal length. Mounting is a matter of using whatever filter (with glass removed) or adapter is close enough in size to bodge on.

I did post a thread on projetor lenses with samples on page 3 Here

I think the lens has more to give as a STF with a better smoked glass iris but the pics show promise. The lens is an ISCO 125mm f/2 to which I have added a back mounted stop.

I have a Schneider Cinelux 105mm f/2 that intend to adapt but I plan to take my time and do it right. Hopefully with a center mounted stop that should delive at faster apertures.

They are both 6 element double gauss designs.

Amazing, you really posted pictures! (sorry, couldn't resist that...)
Well, just start a thread for samples of projector lenses en be done with it! No use talking about it any further, just post those and show us that wonderful STF-like picture (that is what you mean, don't you? You're sometimes quite cryptic...)

I don't see the problem Blame. Like Addy says, we'll just add a category Projector lenses.

I've adapted several of these and used them for the Day Prime Challenge (see here for instance).

It would be nice to add them in this subforum too.

We might also make a category Enlarger lenses. They are usually M39 but as they have no helicoid they can be said belong to a special category.

I also adapt lenses (or rather lens units) of old folders and use these on E-mount cameras (see here for instance). What name shall we give to that category?

It's fun adapting and using all these lenses, and accommodating them in this subforum is not 'difficult' at all.

If we define “mount” as a means of attaching the lens to a camera, every lens that can be attached to a camera has a mount. I think this is a useful definition of mount, although it there will be some “mounts” without a name. But, e.g., a non-interchangeable lens modified to be mounted on a Sony Alpha qualifies as an “other mount lens” by this definition and there have been posts of such lenses on this “other mount lenses” forum (even when it was called “M42”).

That would be the "darosa is cooler than we are" subforum.

More seriously, I think a category for all the off-the-wall stuff together would make sense.

It could be something like "Weird and Crazy Adaptations" if that wouldn't offend people. More tame would be something like "Non-removable lenses" or "Non-interchangeable lenses".

I would vote with thornburg.

One catagory for all the oddeties without regard for mount. Anything that lacks ether a helicoid or an iris.

I do have a fair collection of enlarger lenses but have real doubts as to their worth outside macro photography. Even the 50mm need a fair amount of stopping down. Anything above 80mm has too large a field of view to be sharp under f/8 or sometimes f/11. Maybe for perspective control?

"Weird and Crazy Adaptations" strikes me as honest and to the point.

One thing I would not like to see included is macro above 1:1. Every bodger comes up with the bright idea of reversing a lens to get high magnification on the cheap. Almost invarably with results worse than just cropping a pic from a decent 1:1 macro. It is best handled by a specialized website like http://photomacrography.net/

Hoo. You used the KO-120M 120/1.8.

I think that is a 4 element lomo. 1 group at each end with a lot of air in the middle.

So is there any outlining to the bokeh and can you unscrew it to put a stop in the middle?

Iggy, thank you for the notice.
However, all those threads you just started have no pictures yet... The thread here is for samples and not just plain index of adaptable lenses. So just to make sure - are you going to add sample photos to those threads?

@Rovhazman

All CZ C/Y (MM-versions only because they can be chipped and Leitax-ed) are on my 'to buy' list

I noticed that some other CZ C/Y lenses I added were filled with samples by other fellow Dyxum members even before I could add samples.

Just thought it would be convenient for allof us if these CZ C/Y lenses are 'pre-configured'. Many fellow members are not aware how to start a lens thread or are just too 'lazy'. It helps them out and I'mm pretty certain pictures will follow.

If you don't feel OK with it I'll drop the initiative right away
Regards

Iggy

Iggy, after some discussions, we decided that opening empty threads for possible lenses that can be adapted to e-mount might lead to endless empty threads and will make the index tiring. This was not the purpose of making this index.
Therefore I am not going to add the empty threads to the index.

Thank you for your understanding.
