Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that appears sharp; it makes use of the Scheimpflug principle. Shift is used to adjust the position of the subject in the image area without moving the camera back; this is often helpful in avoiding the convergence of parallel lines, as when photographing tall buildings.

Your premise that a tilt lens can help control converging verticals is incorect, this is what a shift lens is for!
Current Pentaxs also allow for sensor shift in liveview which to a limited extent performs a similar function

Too true.

Yes, use 'M' mode and the green button for metering. The lens will perform much better around f/5.6 or f/8.
You're lucky the K-70 can cope with f/2 @ 1/6000 sec. In the days John referred to those film cameras couldn't with some only offering 1/500, and at best for the top models 1/2000.

I normally find a pencil rubber solves the problem.

Autofocus speed seems to be down to each individual lens rather than the camera body. Hand holding for pixel shift sounds a compromise for obtaining quality results which is why one would surely use it.The improvements were

Same sensor etc. etc. so my thought is the mkII was purely to extend the shelf life of the same camera (and sell a new one to people who already own one!)

IMHO To all intents and purposes they are the same.

Have you tried the 60-250 on the K-1? Seems fine to me even with the baffle still in place.

As I'm interested in mounted slides, it would help if the mounts were dated with the processing date (Kodachrome used to do this). Do any of the above mentioned processors do this?

Anyone know if there is an improvement with liveview (I guess there could be as the mechanical shutter and mirror has nothing to do.)
