Alunfoto has been on my blog list for a long time. This is Jostein Øksne's blogsite and his images are some of the best taken with Pentax DSLRs. Jostein recently purchased a Pentax 645D and is really making more impressive images. He has over 100 pictures featured in the Pentax Gallery, and I believe he has the most accepted images on the Gallery. I may be wrong at this time, but I know he was at the top last year.
His Blogsite is Alunfoto. Pay him a visit, and tell him I sent you.
