Which size DeluxGear Lens GuardTM do I need for the rear of my lens?
For the Front of my lens | For the front with a Hood | For the Rear of my lens
To put the Lens Guard directly on the rear of the lens:
Step A: Locate the widest point of your lens within 1 3/4” (44 mm) of the rear edge.
Step B: Using a piece of string, measure the outer circumference of your lens at its widest point in the rear 1 3/4” (44 mm) of your lens.
Step B: Measure the outer diameter of the rear of your lens at this widest point. To do so:
1. Wrap a string around this point to circle the lens exactly once.
2. Measure the length of the string required.
3. Divide that length by 3.14. The resulting number is the diameter.
Note: Do not go by the filter size.
Step C: Consult the Size Chart below to determine the size of Lens Guard to fit the rear of your lens.
