Cine Ring (80mm O.D.)

The Cine Ring brings your still image lenses one step closer to actual cine lenses and thereby makes your life on set easier. One of the disadvantages of using still image lenses versus cine lenses is that they all have different front diameters. Our cine ring screws into the front thread of your still image lens and brings the front diameter to an industry standard 80mm. It also provides you with a common front filter thread of 77mm. Your lenses are now compatible with many cine accessories that attach to the front of the lens. You no longer need to worry about having a lightproof connection between your matte box and your lens. All you need is an 80mm donut or bellow, and all your lenses will fit perfectly. Also, you can use clamp-on matte boxes and shades that attach directly to the 80mm adapter ring (given your lens can support the weight of the clamp on matte box). Another advantage is that you no longer need to purchase round filters in different sizes for your lenses. You can just start buying 77mm filters and they will fit all your lenses. Also, you can now use cine front caps instead of the flimsy still image front caps, and you only need one size caps that now fits all lenses.
Definitely a must-have item for any serious shooter who works with still image lenses.

About “the lip”
The lip on Cine Rings serves as a hard stop when pushing the matte box against the lens preventing light leaks, a crucial function that is often overlooked. The width of the 80mm front section is still plenty deep for clamp on accessories. Without a lip, you always have to be careful not to push your lens too far into the matte box. We found that out by trial and error and that is why we came up with “the lip”. You can always be confident that there are no light leaks that could potentially ruin your shot. If you take a look at real Cine Lenses, you will notice that they either have a lip (like the Zeiss Master Primes), or they have a very deep barrel which makes it almost impossible to push the matte box too far onto the lens.

Advantages:
– Common outside front diameter of 80mm across all your lenses.
– Makes your lenses compatible with many cine accessories (shades, clamp on matte boxes, etc.).
– No need to switch donuts or bellows on your matte box when switching lenses.
– No need to purchase round filters in different sizes. All lenses will now have a 77mm front thread.
– You can now use professional cine front caps to protect your lenses.

In case we don’t have a Cine Ring that matches the front diameter of your lens. You can purchase a common step-up ring that brings your filter thread size up to 77mm, and then use our 77mm Cine Ring.
