Just use FF mode and crop if and when required to your liking, many DA lenses will go bigger than the crop mode.

For example, the HD DA 20-40 f2.8-f4 Limited works on full frame from 23mm-37mm without hard vignetting and the IQ is amazing. Therefore you'll get more out of your DA lenses although some like the DA15 not so much.

PentaxForums has a FF compatibility chart for every DA lens grading them from A - D, even zooms at varying focal lengths.

Super. Now the 12-24mm seems ok at 18mm and 23mm is this in full frame terms? 18mm in APSC is about 27mm in full frame equivalent.

It is in terms of mm of focal length 18mm is 18mm whatever format you use it on.

If you have been told the 12-24 lens works ok on FF between 18-24, then at those FL it covers the FF sensor.
