Thanks to Algernon,Chris and Gwyn for the extra input. I guess the Customer Support people are being ultra cautious! Anyway, I'll see how I get on with the F. I may end up with the O-RC1 anyway as I also have an Optio W60...but I'm waiting for the Customer Support guys to confirm if the two are compatible.

Thanks again for all your contributions - I'm new to this Forum lark and it's been a great introduction!

Just got this back from the Pentax Support team:
"Dear Mr. Breewood,

Thank you for your enquiry.
Unfortunately this remote is not compatible with K20D.

When replying, please make sure this email is included.

With kind regards,
Pentax Digital Camera Support Team"

So it looks like it's the Remote Control F for me!

thanks Gwyn and SmutjeUK for these comments - I'll go ahead and tell Santa where to get one for me!

Hi there,
is there anyone in the Forum who can advise me if the Pentax O-RC1 remote control will work with the K20D?

Many thanks.
