Focus results for 17-40mm lens
Aug 8, 2007

Greetings everyone,
Could someone please take a look at my focus test results
and let me know if you'd consider this acceptable? It looks
good enough for me, but I wanted a professional opinion.

In regards to the test setup, the camera was positioned level
on a tripod, set to 40mm-F/4, and the chart was positioned
at 45-degrees. Center AF was used and the tripod was raised
until the center AF lined up with the focus line. Thanks!
