The BlurFix Air Professional 6-Pack includes all six of SRP’s BlurFix Air Filters. This pack is intended for customers who desire to have the ideal filter for any given situation. A UV filter is included for gimbal balance and lens protection when some of the other filters isn’t 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 transform more pronouced the higher the vibration frequency and the brighter the shooting conditions so the ND4 and ND8 filters allow for scaling the effects of the ND filter in line with conditions. The ND4/CP and ND8/CP filters are SRP’s probably the greatest filters which combine the artifact reduction propertes of neutral density filters with the glare reduction and contrast enhancement of a circular polarizer. All BlurFix Air Filters are produced from two pieces of CNC machined Delrin® in order that the filter glass will also be easily got rid of and cleaned with the provided microfiber patches (one patch included with each and every filter) and SRP lens cleaner.
