Looking at the Acratech ball heads, and know that Wimberly plates will work them.  So will the Kirk collar fit in the lever-type Acratech ball head?  And from Denis mentioned, the collar could be screwed to a QR plate, then set on the ball head.

Worst case scenario, send the head back & exchange it for one that works.

From what I have read, Wimberley and RRS plates have same tolerances and will work in lever release clamps from each other. I believe RRS lever clamps will not tightly hold plates from Kirk or Markins. Kirk, Markins, and RRS screw clamps will hold any of them. Markins lever release QR clamps can be adjusted to fit any of the plates but generally are adjusted to fit a specific brand plate, not a routinely recommended field adjustment. I do not know specifically if acratech and Kirk use the same dimensional tolerances (I use Kirk, RRS, Wimberley, and Markins stuff). Kirk and RRS are very friendly and very helpful if you give them a call. I have a RRS replacement foot for the Nikon 70-200 f/2.8 which attaches the same as original and is compatible with the clamp on ballhead. I think the kirk collar for the f/4 does not need an additional plate as the foot is the plate and should be Arca-Swiss compatible.


Thanks Darrell,

Will continue to dig to see if someone has used or tried that combo.  In process of lining up the components for a DSLR, and every little tidbit of info helps. 


It appears that the Acra Tech QR lever clamps do have an adjusting knob which should allow use of plates from various manufacturers, i.e. Kirk, RRS, Wimberley, Markins.
