Seems ages since I last had a Waggledance

I've got two of them one for the shutter and one for the flash. The lead you see on the right has a red plug on one end that goes into the receiver and a small jack plug that goes into the release. It also fits Canon. I'm quite sure that the K-x hasn't got that jack plug socket (mine's a K20-D).

I think they have just assumed that all Pentaxes are the same and have made a mistake It's a very good price though as long as postage isn't excessive.

Editostage if free so that makes it about £19 - £20 which is about what I paid for mine a year ago.

That lens is worth £50 - £70..... Go For IT!!!

Yep! that one shows the small jackplug in the camera.
The receiver doesn't have to go in the hot-shoe it can
just hang from the jackplug socket, leaving the hot-shoe
free.

I see it also works with the K1-D..... they must know something
that we don't

The Jupiter 'a' lenses use an interchangeable mount system, similar to a T2 mount held on by 3 small screws. Not sure if a LTM was is available or not. There was a very rare 'K' Bayonet one although the Pentax official M42/K adaptor is probably a better fit.

Has it been voted into the Pentax Gallery?

I suppose the close focus of 4M isn't quite as bad as it sounds,
because the image size is probably the same as the DA* at 3.6M

Nice shots Bob.... my viewfinders always Hazy/Misty in the
morning until about 10-O-Clock!!

Wanna Bet!!

I've got the Jupiter 135mm's 11A and 37A both similar and superb performers and still very cheap.
