>The Kirk D200 "L" Bracket DOES fit the D300, I have one fitted!
Thanks for the clarification
I have to admit I have not tried a Kirk BL-D200 on a D300. My statement was based on the fact that the Kirk PZ-109 dedicated plate for a D200 will definitely not fit a D300. I have just tried it again to be sure. The problem is twofold - the D300 is a millimetre or so deeper from front to back across the baseplate, but more importantly, the D300's tripod socket is nearer the back of the camera. It's difficult to understand how the BL-D200 could overcome these difference to sit snugly on the camera.
Do you have a picture to illustrate the bracket in place?
