Whilst I love using my Action 6 camera there are times where getting the perfect image can be difficult because of the lighting and that's where this little set of filters comes in. I've had several products from K&F Concept and they've become one of the brands I now look to as they've been producing some quality kit and this filter set is certainly well made.Inside the box you get a nice plastic case that holds all 6 filters which are set snuggly in a foam base. The base has cut outs around each filter to enable you to easily remove the one you need without getting your finger prints all over it. The plastic case is quite sturdy so would provide ample protection when placed in your bag. The filters are easy to install as they simple cover the camera lens and are then pushed in to place and are firmly gripped so there's no chance of them coming loose during use.The filter set I ordered includes 4 ND filters (8, 16, 32 and 64), a black mist filter and a CPL filter. To be honest whilst using the ND filters it can be difficult sometimes to see a huge difference going from one to the next but it is considerable between the lowest and highest so it takes some playing about with them to get the desired effects depending on the available light. The black mist and CPL filters on the other hand I use quite a bit when there's quite a lot of light as they do make noticeable differences with softening or removing reflections.For the quality and performance of these filters they are quite competitively priced and complement the camera well to give you options for all lighting scenarios and I would therefore highly recommend adding a set to your kit.
