Pentax USB lead

I am sure the answer to this question is in these forums somewhere, but after about 20 minutes and several possibles, I still haven't found it, so I apologise if I have missed something obvious.

I want a second USB lead for my K-x and it looks as if this one will do it USB Lead Cable Pentax DSLR Camera X70 K-7 K-x Km K7 Kx on eBay as it says kx at the top. However in the actual text is says
"USB Data Cable for Pentax Optio Digital Camera"

Are all Pentax USB leads the same? If not, will this one work with my K-x?

Many thanks for all advice given.

Pentax website shows K bodies and Optios uses the same I-USB7 cable. This should work on a K-x.

I believe it is a standard MicroUSB (A) type connector to a standard A type USB connector.
Both male ends.

Have a look here:

The female body connector can also output video signals, but that should not worry you.

Having looked at both articles, in particular at the pin-outs, I don't think it is a standard USB connector. Both the MicroA and the MicroB diagrams show 5 evenly spaced connectors ("pins").

If you look at the camera end of the Pentax lead (I must confess I had to use a magnifying glass) there is room for about 8 pins with 3 blanked off in a "1 pin - 3 blank - 4 pin" layout.

Definitely looks non-standard to me, but thanks for the article, and thanks K57XR for finding that on the pentax website. Could you give me a page reference?

I haven’t really checked the USB port on my K-x but I believe you're describing an 8-pin Mini-B connector instead of Micro USB. Please check this link. Does it look like the female port of the second connector from left?

Here's the search result for "I-USB7" cable from Pentax website

It looks as if you are absolutely right. I had no idea there were so many USB connectors. So the lead is a standard one, if a little unusual.

Thanks for all the help (and the education )
