Have to agree with you Steve. It's a little hard to work out the point of focus, I think the end of the nose is about optimum, but I can't see any deterioration in noise from the first example to the last. In fact some elements of the highest example, eg the cats 'eyebrow' hairs seem to be better than the others. I hope it is accurate, because for me the noise control has been one of Pentax's biggest letdowns and the main reason I've been considering switching to Nikon after 30 odd years as a Pentax man. Maybe I won't have to, I hope so because the specs for the K5 are excellent and as usual the build quality will be class leading.
