The only topics I can think of that would specifically require a PP technique are montages, mono or Hdr. Possibly panoramas.
I also remember we had a theme commercial for the fortynight, I believe it was Hefty who came up with that one.

Cheap radio triggers, simple solution!
Here is a list of trigger voltage link
Depending the type of 285 it should work on Pentax without a problem, it looks like you have to knowledge to check it.
Pentax don't want to give a rating but from topics on Pentaxforums.com it seems like Pentax has said that it is confirm with the ISO for the hotshoe and that one is rated for 24 volt.

Also I would never shoot groups at 2.8, think i read that up there somewhere...
You said you like the 85mm f/1.4 on the Canon the equivelant for Pentax would be 55mm f/1.4 but since that's a short focal length the DOF at f/1.4 is wider. At points where the DOF would be too small you can shoot around 1 stop faster with APS-C so that means a differnce between ISO800 on APS-C or ISO1600 on 135formatt.
It was just to show that the gain in low light from a 135format would not be so much as it appear at first depending on your lenses and shooting style.
If you like flash controll you need to look at Nikon those have the creative lighting system and you can controll the off shoe flash wirelessly from out the camera.

You also have the DA21 you might think about getting the other limited lenses like the DA40 or DA35 and if you can stretch it also a DA70.

The one thing I did like about the Canon 7D and Bigma with OS I borrowed was that you can see it settle down in the viewfinder before taking the picture whereas with my K10D it's all over the place and your not quite sure its sharp until viewing on screen.
Does the bigma has two OS modes?
I know the Canon 70-200 f/4 had two modes and how to set himself.
One was to constantly have OS on and the other was to wait for when the shutter was half-pressed and they also had a mode for panning I believe.
