Well, not to sure if I will dump the pentax to use the lens, I believe the Nikon d90 is compatible with the old lens too. I have been talking to my local camera vendor and he suggests that there seems to been a market for interchangable lens to different camera bodies. We might see better quality adaptors made by the majpr brands brought into the country. Better than relying on the nasty cheap China markets from ebay.
Thanks for your input, good luck with your endevours
Paul.
