I have a Sony A100 DSLR and just picked up a Tamron AF 90MM F/2.8 DI
that I use for macro shooting. The issue I have is that when I get
tight on stuff I dump the AF (Auto Focus) and go to manual focus to
eliminate the hunting of the focusing. When it looks crisp and clear
in the viewfinder I take the shots and it is a tad blurring in the
image. So what I am thinking is that diopter adjustment is out thru
the viewfinder and when it "looks" focused thru the viewfinder, it's
far from focused for the shot.

So my question is, how can you accurately get the diopter adjusted to
match what the image is??? I am still hanging in there with 20:20
vision but I need to get the dioptic zoned in so when it looks crisp
and clear, it actually *IS* crisp and clear.

In macro mode the depth of field is so narrow that any longitudinal move
breaks the focusing. Are you using a tripod and shooting an inanimate
object?
