I picked up a 10X Mitutoyo Plan Apo Infinity-Corrected Long WD Objective.
I bought a 70-200mm f4 lens to mount it to.
What is the filter size on the Mitutoyo? I measured it and thought it was a 40.5mm, ordered a step down ring, but it doesn't fit. It is just a little too big, so I figured a 41mm but there doesn't seem to be anything out there this size.
Thanks!

Sounds like you have a Mitutoyo BD.
http://www.photomacrography.net/forum/v ... hp?t=12483 says that it's M40 x 0.706 (36 tpi), and suggests some options for this hard-to-fit thread. See page 2 of the thread for the official Mitutoyo spec.
