The Nodal Ninja R1/R10 Lens Ring for Sigma 8mm Canonfrom Nodal Ninja R1/R10 Lens Ring for Sigma 8mm Canonis a dedicated ring that attaches the Sigma 8mm Canon mount lens to an R1 or R10 panorama head. It attaches via the built-in ring clamp, and is built specifically for use with the unique design and dimensions of this lens.

An included plastic insert is placed between the outer metal ring and the particular lens it is designed for. This dedicated ring allows a contoured fit and increases the area in contact with the lens. A large clamping area reduces stress on the lens when it is attached to a camera body.

Arca-Type Quick Release    90 & 30° Index Markings    Contoured Lens Ring for Added Grip    Plastic Insert Reduces Wear on Lens

To increase the area of contact with the lens, a contoured plastic insert is placed between the outer metal ring and the lens.

The large clamping area reduces stress on the lens barrel, reducing the risk of damaging it when a heavy camera body is attached.

The mount is attached close to the camera to reduce stress on the lens due to the weight of the camera body.

Roll the camera and lens in any direction, including popular 0, 60, and 90° positions.

Index marks for every 90° and 30° are located at the front and back of the ring, respectively, for easy alignment.

Having the ring mounted to the lens, rather than the camera, makes it possible to reproduce the same perspective and settings with different camera bodies - and is quicker to set up.

The Arca-type compatible quick release design can be mounted directly to other Arca-Swiss compatible systems without using the R1 or R10 panorama heads.

Its design is great for use on a monopod or high pole when you need more stability or reach.

An optional advanced rail stop is available to remember NPP settings (sold separately).

Q: 9. How do you know when the tripod base is level if used, for example, with a Manfrotto 303SPH QTVR Spherical Panoramic Head (which doesn't have it's own level)? Would you put a bubble level from a hardware store on the horizontal rail of the panoramic head? A two way bubble that fits on the hot shoe (e.g., by Novoflex) would help some, however, the camera could be level in one spot but not when rotated, if the base isn't level--which is the point of trying to level the tripod, right?

A: You will need a level. I am using this with a Nodal Ninja Ultimate M1-L w/RD16-II (F8102).It has a level on each rail. The EZ-Leveler-II makes it very quick and easy to level the pano head. When I first bought the pano head I didn't buy the level. I would have to shorten a tripod leg. This is time consuming and a PIA. The EZ-Leveler-II makes it a snap to quickly level the pano head. Well built and easy to use. I would buy again.

Q: 10. how much height and width does this add to an arca rail when attached?

A: The dimensions for the Nodal Ninja Arca-Type Stop Plate are 44mm x 9.5mm x 6mm.
