Originally posted by AndyB But according to their website they state
"If your camera does not support a wired remote, it could still be partially supported if it supports IR or wireless remote control methods."
And they list just about all Pentax DSLRs as being IR compatible except the K-2S which led me to believe it might be partially compatible since I have used a generic IR remote in the past on the K-S2. I have tried contacting them but no response so far.
After posting, I spent some time with the Pluto user manual and their Web site. The supported functionality via IR is vague. All that is for sure is that B-mode triggering is not supported.* Your K-S2 IR works the same as other Pentax dSLRs, so I would expect that the Pluto should be able to trigger your camera by that means, though with "limited functionality". It would be nice if they had a feature matrix for IR.

* There may be a workaround there in that your K-S2 supports two modes for B-mode timing. Mode 2 allows start with one pulse and stops with another.
