Cool-Lux LuxGear works great

By Samuel

I bought a set of these because of the material choices they made. There is just enough stretch to fit a lot of lenses well and the material grips the lens ring pretty tightly; you are not going to do better than this. I quickly warmed up to using a generic barrel sizing for the product line as you get the most coverage possible and using the printable sizing strip worked like a charm. I am currently shooting Nikon and it's rather ironic that even if I change manufacturers, the rings can come with me.

Great product ... make sure you measure properly.

I love this concept for upgrading a simple focus ring to something geared for professional use. Its very simple idea and I hate the look of the strap-on gears with giant bolt on top-- it gets in the way. This product is well constructed and works perfectly with standard follow focus systems.  Just be sure to measure it properly -- best to be one degree under your measurement. So if your lens is 72mm -- get the one below -- otherwise it doesnt fit snug on the lens.

Is the rubber strong enough to resist the torque of a Title Nucleus motor? (Title rings are not strong enough even if they are 0.8)

The Cool-Lux LuxGear gear rings are designed to be compatible with all standard follow focus motors.

Does this work for the Sigma 18-35 art lens?

Does this work for the Sigma 18-35 art lens?
Asked by: JUAN CARLOS
It will not. The Sigma Art 18-35mm lens has a outer diameter of 78mm. Instead you would want the Cool-Lux LuxGear Follow Focus Gear Ring (78 to 79.9mm), B&H # COLG7879. This should work with that lens. https://bhpho.to/2r2qXr6
