NEW publication — Making Sharp Images
It only took me 5 years or so.
Get it now, then save yourself 5 years by reading it.

This is great stuff!! I started investigating my images more closely back in 2008 when I attempted to "AF Fine tune" lenses for my Nikon D3. I have been testing/elminating my lenses ever since. With this information, I can now understand some of the weird stuff I was seeing. — Al Leese
