BlurFix Air Essentials 4-Pack (UV/CP/ND4/ND8 Fitler)

The BlurFix Air Essentials 4-Pack includes
the four most commonly used filters for multi-copter and lightweight
applications. A UV filter is included for gimbal balance and lens
protection when one of the other filters is not being used.  A Circular
Polarizer is used for applications where glare reduction is required and
applications where more contrast is desired between clouds and sky or
on the snow.  The two Neutral Density filters reduce artifacts caused by
rolling shutter including “prop blur” and vibration induced “jello”.
The artifacts become more pronouced the higher the vibration frequency
and the brighter the shooting conditions so the two ND filters allow for
scaling the effects of the ND filter based on conditions.  All BlurFix
Air Filters are made from two pieces of CNC machined Delrin® so that the
filter glass can be easily removed and cleaned with the provided
microfiber patches (one patch included with each filter) and SRP lens
cleaner.
