You've got that ugly thing hanging on your wall??? Just joking. I'd be proud to hang it on my wall. Pixel peeping might be fun for those who do it, but I'm all about the story, the mood, the impact.
That said, I'm pretty sure my D7000 has a focus problem. I never noticed it when shooting things with great depth of field. But lately shooting flowers, birds, bumblebees, butterflies, etc.; things where I am going for a narrow DOF, I am having real problems. I have been trying a variety of lenses to see if it was lens related, but apparently not.
As much as I hate to, I guess it's time to get Lens Align or some such. Rather spend time trying to find great images.
