I just played a bit more with the RRS L-plate on the K-3. It will take some Dremmel work to get a good tight fit.
The positioning of the tripod screw means that neither the front nor the back lip on the plate will fit around the base of the camera. The back edge is off by less than 1mm, the front right edge will take more work as the lip is a bigger chunk of metal, but what remains will help to secure the plate in position. If you have access to a good machine shop, I would probably enlarge or relocate the hole for the attachment screw so as to avoid doing any trimming on the rear lip. http://photos.stanhalpin.com/p155717848/e35d64301 stan On Jan 20, 2014, at 12:29 AM, Ken Waller <kwal...@peoplepc.com> wrote: > Thanks for the info Mark. > >> I could drop them both on a scanner and scan the baseplates if that would >> help. > > I'd apprciate that Mark. > > I'll probably get the RRS L plate for the K-5 as its appears to be the only > L plate currently available that's even close.
