I already told you that I was doing lensbaby effects by manually tilting lenses in front of my cameras well before Lensbaby existed and probably also conceived.
Well tonight I pushed the experiment a little further and instead of regular lenses, I used a slide projector lens, the Leitz Colorplan 2.5/90 that I took off my projector.
As you know, projector lenses are housed inside long tubes, which makes them ideal for this practice of unorthodox photography.
The Colorplan 90 focuses at about 2m distance when hold to the camera "naturally" (that is, with the end of barrel in or near contact with the opening of the camera.
Of course, by using your hands as extension bellows, you can get as near as you like.
In practice, this turns the Colorplan 2.5/90 into a Leica portrait lens with macro capabilities!
Of course, being "free-hand photography", you can tilt and shift to your heart's content (and actually, it is quite difficult not to!).
Here's some samples that I took:

Very nice bokeh for a fast lens, I'd say I'd consider mounting it with a proper bellows or else with a flexible tube having an adapter at the camera end - just to keep the dust out.

Thanks Veijo. I already thought about the bellows but dumped the idea because it would prevent tilting, which is half (or more) of the fun part. The flexible tube sounds ideal instead. Fascinating solution.
I see two problems though:
1- how to secure the flexible tube firmly to a lens adapter
2- I'll still need the lens at my projector from time to time!
For the moment, here's another hand of samples. When handled carefully, this technique allows for very precise defocusing of selected photo areas:

Take an M42 extension tube and fix the flex to it.

Try to find a flexible tube which is tight fit around the lens body. Or get another lens and shorten the body for a longer focusing range.

Great idea.
Actually, this shows why I suck at handiwork. I have a decent (I think) artistic creativity, but I have near to zero practical creativity. Yet to make some craft work, creativity is just as necessary as with arts. but evidently in our brains there are different creative zones. _________________ Orio, Administrator

Excellent pics.
A flexible tube I've seen somewhere on the net used for just this, is a section of a toilet plunger. The guy used it to tilt and shift a Med Format lens iirc. Other ones are the rubber gaiter off a car steering link or a motorcycle front fork.
There's no shortage of places to get something suitable. _________________ Dave - Moderator

I think it's because we're using them as macro. All macro lenses display good bokeh (when used in macro). I bet that if we could focus the projector lenses to infinite, we would get bad bokeh from them also in reasonable percentage. _________________ Orio, Administrator

No aperture blades thus perfectly round aperture, isn't the key for nice bokeh ? _________________ Switching from M42 to Minolta MD & Contax/Yashica |

Yes, but not only that. There is more to it than just the round aperture. Otherwise all the old lenses that show a perfectly round aperture when wide open would have fantastic bokeh. I know several lenses that produce crappy bokeh despite the circular aperture. _________________ Personal forum activity on pause every now and again (due to job obligations)!
