you can get from dealextreme, cheaper but you have to wait for it to be shipped.
genuine pentax offering is way too exp..Artworkfoto from mass sales sells the infrared remote shutter for around 13 dollar.
Where to buy?
No need to wait for it to be shipped. You can email Emjay, Pentax's agent and check if they got it and get it from them instead, that's how I recently got my Remote F.
Wil lthis work with our K7?
I help my friend to buy this for his W90, and I tested it on my K-X and it works. Not sure about the K-7.
Thanks Bro. If works on k-x then should work on K7
Got mine off eBay, and just got it today. Works with K-x, but have not really tested how far it can reach. The auction page says 8 metres.
