Images are okay "as is" for web use, but any I see that might be worth working on will be taken into the office and put through LR!
Thanks everyone for your ideas and responses.

I've got the 35mm slides covered - I've convinced SWMBO that she should view them all first and whittle out any that she does not want, which will save me a lot of time and might give her an inkling of how long it'll take.
My problem is turning the film negatives into positives - what do people use?

Anyway - SWMBO has tasked me with undertaking this exercise... has anyone done such before? If you did, what software did you use to turn the scanned negative into a positive for working on in LR etc?
There are also in excess of 3000 35mm slides to scan, but that'll be much more straightforward. I hope.

If someone wants to do the same for us soft southeners I'll be interested (unless I am travelling)...

After some posts last year I'm now convinced the issue does not lie with the SDM Motor in these lenses. I strongly suspect it points to a capacitor (or capacitors) on the circuit board, which need to be charged in order for the motor to operate. If the lenses are left unused for periods of time, the caps lose charge and won't re-charge when fixed to the camera. We've seen loads of posts from people who use their SDM lenses regularly and don't have issues, whereas people who use them sparingly do.
I wish Pentax would come clean and tell us all what causes the problems and how to avoid them. My 50-135 will not work when first fixed to the camera, but after 30 seconds or so it does start working 100% normally, then I have no further issues. This lens has the latest motor.
