I am now officially curious and confused. Yes i know thats standard.:-).
I have 4 nikons, the D1 had back focus issues, that Nikon said it di not have, but would fix if you sent it in. My other 3 have no problems. I and others have noticed problems with the K10D and now all of a sudden Pentax is allowing the owner to adjust focus issues with a variety of lenses. How do i read this.??
