35mm Modifier Information
1. May cut incoming light by as much as 50% depending on brightness of conditions
2. Depth of focus increases by approximately 50%
3. Modifies view of mirage and target
4. It employs no lens. It is simply a perforated aluminum disk, weighing only 1/4 oz.
I don't like using the disk in overcast conditions. I use it only in sunny conditions.
Others perfer it installed for all shooting conditions. YMMV.
