Hardly getting over it.
A 28mm is a good one on a camera with an APS-C sensor - equiv to about 42mm on a full-frame SLR,http://en.wikipedia.org/wiki/Pentax_K-mount
With Pentax you do. The control motors in Pentax DSLRs are in the body and can drive the mechanisms in older lenses. I've got a K200 body and it drives Sparrow's dad's old lenses just fine (although you get a cropped portion of the original image size, as the sensor is smaller than 35mm)
Just a little bit.EDIT: I am well late to post this information
