Many thanks for your assistance.

Thanks for your comment.
Well Leitax offers such a solution for some OM lenses. But i believe it is the same situation with the Nikon and Pentax bayonets before.
At first there were cheap adapters for Leica to Nikon on the market, since few weeks bayonets for Leica to Pentax and hopefully in the future for OM to Nikon or Pentax too.
Perhaps you will remember at this thread and can provide me a short notice if you will see such a bayonet in the future.
Thanks again.

No problem . By the way, doing a simple mount conversion in China just cost around US$50.

How this will be done and is it not possible to do it by myself with the parts I need for this conversion ?

Is there enough room inside the Pentax bayonet for the OM mount + adapter? The Nikon lenses are a "press fit" in the Pentax mount so there's not enough space for an adapter (or it would be really, really tight).
A mount conversion is somewhat easy but an adapter would be sweet

You can measure it yourself. An adaptor can be made if and only if it is physically and mechanically feasible.

The OM has about 1.5mm more register distance than Pentax lenses, and it looks like the Leitax adapter is a bit thicker than the stock OM mount.

Register difference: OM 46mm - PK 45.46mm = 0.54mm

I have mentioned in a few threads here that I have slightly modified OM and C/Y lenses to fit PK mount cameras. The problem is that the bayonet blades on the lens are slightly too thick to fit underneath the PK mount lugs. My modification is to use a Dremel blade to shave away a little of those blades, tapering them back about 10mm. On OM mount, taper all three blades. On C/Y mount, don't taper the notched blade.
These modified lenses will still fit their original mounts, and will now press-fit onto PK mounts. But the fit isn't secure, and I would not trust a long heavy lens this way. My next step will be to use a Dremel blade to cut a small notch into the lens base, 1mm wide and deep and 6mm long, for the PK locking pin to latch into. I have not done this yet but it should work.
I have so far modified only inexpensive lenses. This surgery would probably reduce the value of a costly gem, which should receive the Leitax treatment instead. But if you have cheap OM or C/Y lenses to fit to a Pentax camera, this works.
