Redrock Micro eyeSpy Deluxe - DSLR 2.0 Rig
The eyeSpy Deluxe Bundle is a comprehensive solution for on-the-go, shoulder-mounted DSLR rigs. (Cameras using battery grips and taller camera bodies like the Nikon D3s, D4 and Canon 1D Mark IV and 1DX should use the Redrock Micro Riser to ensure proper alignment with accessories).
Redrock Micro focus rings
The eyeSpy Deluxe includes a set of three micro-focus rings that fit a wide variety of lenses. The different sizes are denoted by the letters A, B, and C. The rings go around the focus ring on the lens and allow the follow focus mechanism to work. You might want to order an optional second or third focus ring so that you can quickly and easily swap lenses on the unit, instead of taking the lense off, removing the focus ring, attaching it to the new lens, etc. If you need the large D-ring (for lenses such as the Canon 100-400mm) please indicate it in the notes as it is NOT INCLUDED by default. For information regarding the various focus ring sizes please see this link at the Redrock Micro site.
