Pentax 645-K adapter on DS
I finally found a replacement for my Pentax 645-K adapter that enables me to use the lenses I've got for the 645n to be used on my digital camera. At least I can now keep the travelling kit (relative) small when I'm shooting with a dual setup.
Metering on the DS with the 645 lenses is done the same as using the camera in manual setting. You stop down the lenses with the aperture ring, take a light reading and are good to go.
The first images seem very promising regarding the resolution I get from these lenses. They have all the sharpness I usually need. I'll post two images here to give an idea about sharpness at 400 iso.
First the general overview.

And a 100% crop of the same image:

Where did you find the adapter? I am looking to do the same thing with the K100D.
As best I can determine, Pentax has discontinued the apapter and there don't seem to be any available anywhere. I think Pentax is missing the boat big time on this. There are a lot 645 users who could use these for digital back-up or conversion without loosing the investment in lenses.
Hello George,
They are indeed very hard to find currently. I got my first adapter from ebay, and a year later I found an unused one in a shop window in The Netherlands.
Pentax would indeed be wise to restart the production of this 645-K adapter to keep the 645 users happy, expecially with the 645D coming up shortly.
