Extremely easy way to get small lenses on m42.
Plastic m42 body caps.
Drill a hole just under the width of your thread.
You should be able to screw your lens into the soft plastic.
You may have to do a bit of trial and error fitting with a file (to adjust the size of the hole in the plastic).
If done right it is very firm and secure.
I've done it with a dozen lenses or so.

I do the same than use hot glue to hold it in properly. It will come off easily enough if you pull it hard.

Hi Ray,

I have some very old SK enlarging lenses with fine threads, Looking at them I would say they are M25x0.5 thread.

It would be nice to get them up to M39 or M42, but I cant seem to find adapters. Have you come across a solution for these?


I'm not Ray, but I know where to find such adapters: Click here to see on Ebay or here from
SRB Griturn in the UK http://srb-photographic.co.uk/m39-to-m25-schneider-adaptor-6130-p.asp
Schneider also has them as part # 92-056001 as "00" to LTM (M25x0.5 is a standard "00" shutter mount)

I'm an engineer, I have to do things the "right way" Wink

I can buy half a dozen in China for the price listed in Ebay. The adapter is also available for '0' shutter with M32x0.5 thread.

I have a Componon with that size thread but have not successfully adapted it to M39 or M42. I figure there must be a solution out there but so far I have not found one.

Hah, I see that when I replied I missed almost whole page of earlier replies giving solutions! Hate it when that happens.

Have a look at this article. In the middle there you will find - as part of the VNEX system - conversion rings for M25, M27, M30 and M32.5 screw mount lenses to M39.

Sometimes i ask myself, why some threads about enlarger lens conversion are made Sticky here, if nobody reads them Shocked
