Okay, I know quite a few guys here have been looking for M42 to PK adapters, especially the original Pentax ones. But these are hard to find now.
Here what I got is a slightly cheaper (but not dirty cheap) version from China - 黎环. It even comes with a nice gift box:
Inside the box, is of course the adapter, plus a PK mount rear lens cap (I'll show you why later on):
Here are two quick comparison photos between this adapter and the Pentax original one:
The obvious differences you can see here are that this '黎环' is a bit thicker than the original one, and it comes with an extra flange at the bottom.
Why putting an extra flange at the bottom? Here is a photo of the rear mount end of a Takumar M42 lens:
You can see there is a pin stick out at the bottom, and a knob (the Auto/Manual switch) at the side. BUT many other M42 lenses (like some Yasika/Voigtlander/Meyer M42 lenses) don't come with the Auto/Manual switch. The only way to adjust aperture is to push the pin in all the time. Some users just simply use super glue to glue the pin in, which is of course irreversible. The best is to use some adapter with an extra flange at the bottom to push the pin in when mounted. But those kind of adapters are even harder to find and a lot more expensive than the Pentax ones, like those Kindai adapters which cost 100usd on ebay!
This above mentioned '黎环‘ does the same as the Kindai one, but only at 1/5 of the cost.
