The LS-80 Ring Lens Support with Arca-Type Collar from Sunwayfoto is a rotating camera support that mounts easily to virtually any tripod. The 80mm inner ring rotates freely inside the outer ring to provide vertical or horizontal orientation while keeping the lens centered, eliminating the need to recompose the shot. A locking knob secures the chosen camera position.

The outer ring is attached to a durable quick release platform that features an Arca-type dovetail. The platform also has both a 1/4"-20 and 3/8"-16 female threaded socket for more mounting options.

Q: 1. How to tighten the umbrella as i don't see the knob?

A: You are correct, the Sunwayfoto CB-06 Cold Shoe Adapter with Arca-Type Base does not have a knob for the umbrella 8mm mount. When using an umbrella is secured by friction only. Adding some gaffer tape around the umbrella shaft might fix it. ProTapes Pro Gaffer Tape (2" x 55 yd, Black) BH #PRGT255B

Q: 2. When installed on a rail what is the height from the rail to the top of the supports?

Q: 3. is it possible that this can used with other lenses that have a dovetailed lense plate?

A: I am using the LS-1 with the KIRK replacement foot on my Canon EF 100-400mm L II lens. They work very well together and support my lens at 2 points instead of 1 on a tripod. I find the combination is noticeably more stable than without it. I don't know if you can use this combo on other lenses . You would have to experiment. Kirk makes individual lens supports for specific lenses. For example,they make an LS-2 lens bracket for the new Nikon 200-500mm lens.

Q: 4. Does the Novoflex NEX Lens collar work with the A6600 and the Sony 70 - 350mm E mount lens, as well as with RRS clamps (the old type with bolt tensioner) ?

A: Yes, the Novoflex ASTAT-NEX Collar Mount with Arca-Type Foot for Select Novoflex Lens Adapters, B&H # NOTMN14, should be compatible for use with the Sony Alpha a6600 Mirrorless Digital Camera and the Sony E 70-350mm f/4.5-6.3 G OSS Lens.
