The 812 Zircon Diffusion 3 Filter from LEE Filters can be used to soften the output of an LED light fixture. This filter is constructed from 180-micron polyester that resists fading from LED light fixtures and is delivered as a 24 x 24" sheet.

While in use, the 812 Zircon Diffusion 3 Filter is designed to exhibit a 0.22 density, provide a 0.6-stop value, and transmit light at 60%.

Q: 5. How does the aperture change with the focal length? (at 24mm, 28mm, 35mm and 50mm)

A: Aperture or F-stop is is calculated relative to the focal length of the lens. The formula is, focal length of the lens divided by the optical diameter of the lens. at 24mm the diameter is 6 = f4 The optical diameter can change as you zoom based on design. In this lens 50mm the diameter is 7.9 = f6.3 Note this is illustration is just to explain how we get f stop numbers I don't know the technical design of the lens.

Q: 6. Does the 11.8" minimum focus distance apply to the entire zoom range of the lens? For example, is the minimum focus distance going to be 11.8" at 24mm, and 11.8" at 105mm as well?

A: That is correct. Since the lens sticks out as you zoom though you still need to step back.
