The K&F filter pack for the Pocket 3 is a perfect combination of flexibility and quality. Needless to say, I am really pleased with this four pack of filters. I like they are all in one "small" case which will help save space when traveling. They are very well designed and built and an amazing bundle for the price.

Let me go through the lenses in order of my favorites.

Wide Angle Filter:

This has passed my Wide-angle Test. I placed four sticky notes on each side of a set of tiles in my main shower. I then take one photo with the Pocket 3 using its own lens and then another with the wide-angle lens.

Pocket 3: You can see three sticky notes on each side of the center dot.
K&F: You can see all four sticky notes on each side of the center dot plus some extra space at the end of the shower/tub.
Use: placing the K&F wide-angle lens on the Pocket 3 was easy and due to its thickness, super easy to pull off.
Image quality: I cannot see any defects in the wide-angle vs the regular Pocket 3 lens and the image looks sharp enough. I will add some color shots in the future.

Variable ND. I love variable ND's because they can give you a little or a lot in one single lens. I do prefer Variable ND's so that you don't have to carry four fixed ND's as opposed to one Variable ND. I tend to use ND's around 32-64 and unfortunately this ND is on the lighter side which is still helpful for certain situations, but not my preference.

CPL: I rarely need to use the CPL filter unless I'm on the water or trying to do something very cinematic or need some saturation. This CPL works well and definitely makes images pop!

Black Diffusion: I have to admit this is my least used lens but not because of the lens, I just have not had a lens of this type so I have less experience with it.
