Arca-Swiss D4m (Manual) Head
This is the manual (not geared) version of the D4 head with screw clamp quick release. These heads are insanely hard to find, and outrageously priced once you find one. I bought this one from Capture Integration last September for $775 and really don't use it enough to justify keeping it. So I'm selling it for a sane $600, PayPal'ed and shipped to the CONUS. I cannot ship internationally. It's in pristine condition and is an exceptional piece of kit.
If you'd prefer the RRS lever clamp to the Arca-Swiss screw lock clamp, I'll add that for an additional $40, installed. You'll get both, so if you ever want to revert to the original clamp, remove one screw and Bob's your uncle.

Thanks for looking.
