Looks like a great setup! the Q is hardly visible in between all this gear!
One question related to the Red Dot Finder. How you use it exactly? Is it just for pointing the camera correctly, after which you use the LCD to focus and compose?
I'm still waiting for Pentax's version of the adapter (with the nice tripod mount they showed), so I can start using my K135/2.5 on the Q (which doesn't have a tripod mount). I'll judge then if the LCD is sufficient to work with. I expect the FOV of the 135mm will be easier to use than 300mm.
