Old small projection lens, quickly adapted, only some quick test shots on my balcony w/o any desire to be "artsy" Wink
















Opinions?

I should have known that it is a French lens from the romantic bokeh. Wink

The 5th picture is really great for a test shot. Smile How do you adapt these lenses? What is the usual mount of a projection lens?

#5 is magic, both technically and artistically
I have LOMO PO500-1 projector lens but it's still collecting dusts because I don't have anything to make a DIY adapter. I hope someday I will have a chance to do something like you're doing here.

Thanks, that were just quick test shots Wink

You could get a M65 focusing helicoid from China, add to the front this adapter Click here to see on Ebay
and this one to the rear to make it M42 Click here to see on Ebay and you're ready to go Wink
(fits all 62.5mm diamater projection lenses, usually from about 80-90mm focal length onwards)

Oh my Gosh, there is a focusing helicoid for this projection lens in ebay Shocked Shocked Shocked ?!? Thank you so much Klaus, words can't expression my appreciation Surprised
I was lucky to get that projection lens for just $30. Based on a review in Russian, there was a great deal, since the resolution of this lens is very high. But I thought the 62.5mm diameter is quite odd, so I just did some freelensing and left it there. Now I have chance again Laughing

Yep, it is heavy, but it works. The Projection lens is hold by three set screws in place and this allows to adjust for infinity focus also.

Good luck and good results I wish!
