Yes have seen it- 1/4" is a luxury in macro think I'm down to much less than 1mm at 5:1.

If I'm not mistaken, with the Canon MPE-65, at f/2.8 and at 5:1, the DOF is something like .07mm. Talk about razor thin!

Interesting, because the mpe booklet lists 0.048mm for those settings ... so an even thinner razor
