olefella > Thanks for confirming that I made a good decision on the Pentax 55-300mm zoom lens.

I'm still waiting for my new zoom lens, hopefully it will arrive tomorrow so I can have a chance to test it out over the weekend.

I just got my new PENTAX Remote Control F today. Woo-hoo! I only had a few minutes to test it out and see if it worked... or not. I'm happy to report that after setting the K-x 'Drive Mode' to 'Remote Control' the remote worked as advertised. I even tried it out after setting the camera's BULB mode. One push of the remote to open the aperture, count a few seconds, and another press to close the shutter was all it took to shoot one severely overexposed photo. Not bad for $12.00 US (including shipping).

WhoDo > The 'Remote F' definitley works with the Pentax K-x. You may want to go back to the camera shop and have another go with the two (2) remotes and your camera.
