I've got a Nikon D70 with only 1 lens. I have a few Pentax K manual focus prime lenses from a previous life, and am thinking about getting an adapter. On ebay I found this:http://www.ebay.co.uk/itm/PENTAX-PK...7310587?pt=UK_Photography_CameraLenses_Lens_c aps_hoods_adaptors_ET&hash=item19c4e1bc7b.(Sorry about the link, no WYSIWYG interface for me...). Anyone have experience with such a thing? Worth getting? I know the Pentax lenses will only work MF, manual mode and aperture priority, but that isn't a real issue for me - AF is a relatively new concept to me, and (I hope) the prime lenses will make nicer pics than the 35-70mm Nikkor that currently sits on the D70...?
