Thin 9mm Profile Ring
- The wider front filter ring helps reduce the possibility of vignetting (the darkening of corners) at wide angles and is not deep enough to accommodate a lens cap
- It allows you to have continuous control over the amount of light coming through your lens in an approximate range of 2 (ND 0.6) to 8 (ND 2.4) stops
- This filter features a 105mm front thread for mounting additional filters or other accessories. Due to the slim nature of the design, not all accessories will fully thread onto the filter. Also, the use of additional filters and accessories may result in vignetting.
Neutral Density Filters Have Four Main Uses
- To enable slow shutter speeds to be used, especially with high-speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high-speed film (above ISO 400) and allow it to be used outdoors in bright situations
- To allow cine and video cameras (which have fixed shutter speeds) to film snow, sand, or other bright scenes which could cause overexposure
ColorCore Technology
- Allows control over the color and density of filters, and the characteristics of special effects filters with greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations
- Offers better control over various densities of filters and creates more exact degrees of filtration
