Hi all,

I have a K-x that seems to me to always be just a little soft
focusing.  I'd like to finally get around to testing it a little
scientifically.  To that end I have downloaded the focus charts etc
from
http://regex.info/blog/photo-tech/focus-chart

I know I'm supposed to test using the smallest possible depth of
field.  Here are the lenses I can use:

Auto Focus:
DA40
18-50 Kit
50-300 Kit

Is the DA40 adequate for determining the focus accuracy of the AF system?

I also have these MF lenses, but am not sure how to best test out the
MF focus system (which is a combination of me and the camera).
SuperTak 50/1.4
SuperTak 85/1.9


Thanks!
