5P cable for LS lenses?

Anyone knowing whether a 5P sync cable to LS lenses exists? There is a 5P sync cord for Pentax 67, which may be the item, but I cannot find much info on this.

I need it to connect the 645 LS lenses to my AF500FTZ.
(I have a sync cable for the AF400T but the 4P cables are not compatible with the AF500FTZ).

5P cable

Hello,

I have short and long 5P cables, but they are 5P to 5P. I use them for triggering my AF500FTZ off the camera (645N, 67II). When I use a LS lens, I use a pc cord and a compatible flash - i.e. Vivitar 285 (with a hot shoe adapter on the 645N). As far as I know, a pc to 5P cable to go from the LS lens to the AF500FTZ is not available, but I could be wrong.

Hi Smolk,

I think all you need is one of those hot shoe(female) to PC cord adapter and a hot shoe(male) to 5P adapter. There is no automation at all with the LS lens other that to fire the flash. The central pin of the hot shoe adapter I think is the same for all cameras. Check out the hot shoe adpater F and and hot shoe adapter FG.

Thanks for the suggestion! So what you suggest is:

a pc cord between LS and a hot shoe(female) to PC cord adapter (for example, http://www.flashzebra.com/pics/0065.jpg or perhaps http://www.bdimitrov.de/kmp/flashes/mounting/HotShoeMV.jpg;
putting the hot shoe(female) onto a hot shoe(male) to 5P adapter (= hot shoe adapter F, see http://www.bdimitrov.de/kmp/flashes/mounting/HotShoeF.jpg)
5P tp 5P cable between that adapter and the flash (http://www.bdimitrov.de/kmp/flashes/cords/sync_F5P.jpg)

That seems logical to me. Indeed, it's just to trigger the flash, nothing else. I broke my AF400T and it seemed problematic anyway, as it did not always fire (I distrust the 4P connection). Moreover, the AF500 is much more mobile, that potato flash is ideal if you're planning it and taking all your stuff along, but otherwise the AF500 fits my bag much better!

It just occurs to me that the first step is sufficient; pc cord to hot shoe(female) to pc adapter http://www.flashzebra.com/pics/0065.jpg, on which I can put my flash. No need for the Hot Shoe Adapter F at all.
(I have that last adapter and the 5p to 5P cord anyway, but just ordered the first shoe adapter.)

Thanks for the help, I'll report later whether it works (but I'm soon off for a while so it may take some time before I get round to do that.)

What you want is the Pentax Hot Shoe Adapter LS (or something fashioned like it), seen here: http://www.pentaximaging.com/files/manual/645_Quick_Shoe_&_Hot-Shoe_Adapter_LS.pdf It's little more than a cable with X-sync plug on one end and a hot shoe on the other with a hot terminal for the center pin on the flash. I've used it with LS lenses on 645NII and 67II and both AF500FTZ and AF540FGZ, and it does the trick.

They may be hard to come by nowadays. I searched high and low for one until I discovered a vendor on Amazon who had one left, but that was about a year ago.
