Foton F-Ring Focusing Lever 80 - 85mm
Out of Stock
F-Ring is a simple, but innovative solution to improving your work in manual focus or zoom mode.
The easy to attach lever lets you adjust focus or zoom, in a precise way and assists with smooth and gentle transitions.
F-Ring was primarily designed to be helpful when filming with DSLR cameras but it also works with many camcorder models as well.
This model F-Ring is designed to fit lenses from 80mm to 85mm in diameter.
Please refer to fitting information below, to ensure you order the correct diameter F-Ring for your lens.
The practical design of F-Ring makes it easy to mount and remove.
Two levers are provided, short and long to match your working style.
Important: The F-Ring size refers to lens diameter, not to filter size.
Decide if you want the F-Ring for the focus or zoom ring on your lens.
Measure the diameter of the lens at the point you wish to fit the F-Ring.
The easiest way to do this is with a vernier caliper. See example below.
In this example, the diameter of the lens is 70.38mm. So, this lens would need our part number FS612 which is an F-Ring for 70-75mm diameter lenses.
