Hi Frank,

According to my DOF calculator, it's right...and it's conservative as it's
based on .025mm COC, instead of the typical .033mm.  Let me know if you find
a different DOF calculator that gives you a different answer.  50mm is
somewhat "wide", as opposed to the 75/1.4 at 1M is 0.012M...and a 110/2 is
.009M and a 135/2 is .005.

Austin
