We received these Zip Gears from Jag35. The Zip Gear is a strap that wraps around a lens to provide an interface with a 0.8 mod focus driving devices. These lens gears have a low profile and can be kept on your lenses to eliminate having to change out the gears for each use. They’re easy to apply, you simply attach the gears to your lens using a Zip tie. The Zip Gear works great with all Follow Focus’s as the pitch on the gears fits most industry standard follow focus systems. And best of all- they’re affordable.
You have the option to choose from Four basic sizes. The small size is around 7 inches, the medium size is around 8 inches, the medium plus size is around 9 inches and the large size is around 10 inches. The Zip Gears come in red or black options.
Jag35 has a metric chart and a sample lens chart for your convenience on their site (click here). The small and medium size will easily work on most AF lenses as they have a very short throw. Don’t worry about getting a size too large, as they can still be trimmed down as seen in the video (above).
