Tell me something you knowledgeable people <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

How does the minimum focussing distance come to play when a FF lens is mounted on a crop camera?
Lets say 85 1.4 vs. 135 F2
85 on crop is roughly the same as 135 on FF. In terms of DOF and focal length both.
But 85 has a MFD of .85 meters and 135 has a MFD of 1.1 meters.
Which means with 85 on a crop camera, i have a 135 F2 with better close focussing ability.
Is this right?
