Looking for cheapest M42. Mounts not lenses.

[Pancolart]

There are many adapters from M42 to XY camera available. But i need cheap, thin M42 mounts.
Ebay search is quite impossible because you cannot exclude wrong results. I was already considering
M42 rings but they'd needed to be cut for my purpose. Plus they don't have the wider side like adapters have it.

Did anyone stumble upon something useful?

[tromboads]

you want the physical mount from a camera?

Surely a cheap broken Zenit would be the ticket?

[Pancolart]

[Layer-cake]

I would maybe check local camera repair shops to see if they have some unrepairable m42 lenses lying around. I normally buy up the broken lenses down here for that reason and nobody is willing to bid on broken lenses so I get them cheap!! or if you know a metal/engineering shop they could do it for you easily.

Whats The project you want them for?

It was not easy to understand but maybe now I understood, and is something I also looked for....
Some time ago I was able to find a step-up-down ring M42 - 52mm, that was explicitly told to be 42x1. Vendor was jinfinance on Ebay, but I do not see the same ring again among its products. However, this should be the same: http://www.ebay.it/itm/52mm-to-42mm-52-42-M42-Filter-Adapter-Ring-/400433618548?pt=US_Filter_Rings_Holders&hash=item5d3bb41e74&_uhb=1

You need M42 reversal adapters for reverse mounting lenses by their filter threads. ebay has them.

Am not perfectly certain what you are seeking. Seems as if you might be wanting to convert lenses with other mounts to m42.

Anyway, a T2 to m42 adapter will give you an m42 male thread. They are not too expensive (circa 5 bucks) and are readily available on eBay, albeit from China. Perhaps just the insert (readily removable) from such an adapter might do you?

Here is an example of the reversal ring:

Not sure why they are this much, the Canon EOS and Nikon ones are less than half the price. The EOS and Nikon ones are much thinner too, I used a few of both to change the mount on unusable lenses before and they are only 1-1.5mm or so thick.

What diameter and thickness you need?

[Pancolart]

Projector lens + barrel + M42 mount.

Ian and Enzo these are both interesting options, thanks.

@Calvin: my thinest adapter is M42/Nikon and is around 1.2mm. I'd like something similar.
Wide, flat side diameter around 5.5-6cm.

@dickb and Ray: i'll dig into those step up/down adapters and filters, they are cheap indeed.

Another possibility is to modify body cap for M42 body to M42 mount
There are body caps from metal or PVC

[kuuan]

great suggestion, body caps might be best and should be cheapest:

I use reversing rings for all sorts of projects including modifying mounts. They are usually 1mm thick and the filter thread can be sawn off. I have modded an OM lens to Nikon using one of these and there is plenty to file off if you want thinner. Reversing rings cost a few pounds only and even the wide ring can be cut off is necessary.

If you want M42 consider an M39 to M42 ring. Thin and nothing else this costs a pound post paid. Is this small and cheap enough?

[calvin83]

There are something similar to your need with 1 or 1.5mm thickness but I do not know the quantity and price you need. It can cost roughly $8 if you just want one or two.

[buerokratiehasser]

M-AF / Sony to M42 are as thin as they get

only
- some (hama "Mi 7000") are a bit too thick and
- you can't get them in quantity for 1 buck, trade is rare

[CuriousOne]

I've bought various M42 to Sony Alpha adapters on ebay. Thickness varied from 0.6mm to 1.4mm.

Another idea is to visit local metal workshop, order them large tube with m42 thread on it, and cut it according to requirements.

[buerokratiehasser]

Ah again useless advice cause I didn't read well enough. I am sorry. MAF adapter is, of course, M42 camera part not lens part.

Cannbalising YS is not such a good idea either, they are thicker, and worth more than whole lenses

T2 to M42 yes

[dickb]

I just came across an interesting seller offering all kinds of m42 adapters. This one seems to offer a nice flange to work with:

Wow. It seems they just made it not long ago with reasonable price.
