Hi Logan,
Ahhh, there's the rub. Canon Zoom lenses may have a distance
scale, but the EF 28-135 IS USM does not have depth of field
scale (but the EF 24mm f/2.8 does).
Although it might be possible to simulate DOF with the DEP
function, I found it easier to remember:
"28mm f/16 2m" and
"24mm f/16 1.4m"
Alternatively, if you adhere to Merklinger's "lens resolution"
technique, you could just focus to infinity, and stop down
until the raw aperture diameter is sufficient for your scene.
e.g. 28mm f/16 focussed at infinity will resolve 1.75mm
