The "super high resolution lens" that is used when one chooses film holder has a larger aperture and less depth of field than the "high resolution" lens that is used when one selects film area guide. In my own testing of the V700 I found that with the super high resolution lens one could definitely see a difference in resolution between plane of best focus and 0.3 mm on each side of the plane. However, to see the difference you need a really high resolution negative with a lot of contrast. I did the testing with the Betterscanning holder, fluid mounting the target on the underside of the glass.
