Also bear in mind that SR is less effective at close distances, so the best results will be obtained with SR off.
As this will vary with shutter speed and distance, it's probably better to believe the advice given by Pentax and switch SR off when using a tripod.

However, if you do filter out the effect of the lighting, you end up removing the very character of the light that makes a night shot attractive. It would be like "correcting" the light of a sunset to make it look like daylight. Is this what we want to do?
Personally, I would think around the positive side of it and alter the composition of a shot to include as much as possible of what I want to show and remove as much as possible of what I don't.
Just a thought!

A lens hood is indeed the most useful accessory and the lens will be fine.

It is nice to be able to use the Quick Shift, which is the one thing that makes me prefer it over the 43mm and 50mm lenses.

I presume the 35mm equivalent will be a Lensbaby
I'm not convinced about the shift theory in the image shown as this moves a narrow DOF into a different plane as required, but still leaves a narrow DOF within that plane. That is not the effect we have here.
Here we have good DOF throughout the image and that is best served by a very small aperture. The shutter speed could simply have been a long one, as simple as that.
