For last few weeks I was creating linear motion lead screw focusing or micro rail. The bottom rail include Arca Swiss compatible dovetail that works with Arca Swiss type clamp while the slider is equipped with quick release clamp. Clamp can be oriented in 4 positional using 2 sides holes. Camera to subject distance can be adjusted in fine increments . Lead screw delivers 1.06 mm of travel per full revolution. Fast positioning can be done by pressing slider release lever and slide the slider on top of the rail. This rail is design to work with small and light DSLR. It is not recommended for heave cameras with long lenses. It does not include any lock down mechanism for slider. Works very nice as a nodal slide.

I had a lot of question about plate and L bracket for Nikon D7000.
L bracket is almost ready. It is in anodizing process. I am expecting it back by end of January. L bracket is 3 part design . Plate , 90 degree connector and side plate. You can remove base plate from 90 degree connector and use it as camera plate. Long mounting center slot will let you slide L bracket about one inch to the left to access side ports on camera body. Nice future to have if you are going to use tethered shooting. I will post picture as soon as part are back. Price is going to be $99.99
