I wasn't directly making a resolution point...however...noise in the image
will decrease effective resolution (not the actual resolution on the
sensor...but rather your ability to use and enlarge the image)...thus using
a faster lens...if it results in being able to use a lower ASA might
increase resolution.  Of course this is not the case when you talking about
optimal lighting conditions, where I agree, the better lens won't help with
resolution.
