V+ Series Filters

Each V+ Series filter weighs only 7.2 grams making it ideal for quadcopter use.  If used with a gimbal, you must check with your gimbal manufacturer to ensure the additional weight is allowable and the V+ Series filter will not cause damage to the gimbal or cause it to over current and go limp.  Like many of our filter adapters, the V+ Series filters are CNC machined out of Delrin® which is more expensive than billet aluminum by volume - this is not just another cheap injection molded product.  Delrin was selected so that the filter will precisely slip over the lens flange on your camera.
There are six different types of V+ Series filters to meet your needs. Filters are used with digital cameras to combat glare and/or rolling shutter effects.  Glare is commonly found on the surface of water and windshields/windows.  A CP filter can be adjusted to cut down on glare and is commonly used in fishing videos or on the dash of a race car.  The effect can be dramatic.  For instance, in fishing videos a CP filter can make the difference between seeing your catch just below the surface or seeing only sunlight reflected off the water's surface.  In addition, CP filters will make the sky appear bluer and cause clouds to have more contrast.  When used in snowy conditions, a CP filter will add contrast, allowing the viewer to distinguish features that would normally be over-exposed.
Neutral Density filters reduce or eliminate the effects of rolling shutter, such as the jello effect and prop blur.  In high vibration environments like a quadcopter platform, the video commonly appears to be shot through a bowl of clear jello.  An ND filter slows down the automatic shutter speed by reducing the amount of light that the camera detects.  This will significantly reduce the jello effect. ND filters come in different levels of light reduction.  Darker ND filters should be used on brighter days (i.e. ND8) and less dark ND filters are used on moderately bright days (i.e. ND4).  Experimenting with different filters in different light conditions is the best way to determine which filter is right.  Prop blur refers to the artifacts that commonly occur when filming a propeller or rotor using a stock camera.  The propeller often is fragmented and is not what's seen by the operator in real life.  An ND filter used in these situations slows down the shutter speed and reduces or eliminates these artifacts.  Again, this reduction depends on the ND filter rating and the lighting conditions.  Experimentation is recommended to select the optimal ND filter.
