Remote Control F in B mode

Just bought a universal Remote Control for my K10D, however, it does not work in B mode. The dealer (Ebay) claims that similarly the RC-F (Pentax own make) does not support B mode. Only the cable release does.

If someone has the Pentax RC-F can this be confirmed to me please? In page 159 of Pentax K10D manual it states in the 'MEMO' point 4: Page 81 explains setting the remote control through the Fn button.

I do not think the dealer is right.

I have a Remote Control F, and it does indeed work as the manual says. B exposures work fine with it.

I can see John Riley grinning, albeit sympathetically...

I've just tried this with the Pentax IR remote.

In B mode, the shutter remained open for as long as I held the button on the remote control.

Thank you for confirming this to me. I will send it back and ask for a refund.

Learnt my lesson... buy only manufacturers' products. At least did not cost me much this lesson.

I just tested my Pentax Remote F on the K10D in "B" mode and it works perfectly.

Thank you all for checking. I will be receiving a full refund on the one I bought, in the meantime I have ordered a Pentax one. Looking forward to receiving it and enjoying it.

can the pentax F remote be locked so you dont need to hold down the button in bulb mode?

No. A clothes peg might do the trick, if it didn't squeeze too tight. The membrane-type button looks like it would be quite easily damaged if you picked something that held it pressed with much force.

Cheers
