Great for landscape photos and more.
Includes: Polarizer & UV Protection filter, front + back lens cap, storage bag.

Had to pick up the size that would benefit me most. Ended up with the 62mm set.
The would be the largest size, based on my current lens selection.
Have a few lens that were smaller and have the solution for that.
Pick up the K&F Concept 18 Piece Filter Ring Adapter Set.
(made of the same aviation aluminum alloy)
The perfect companion to this set.

All filters and caps are made of aviation aluminum alloy.
Have anti-slip teeth on the edges CNC'd into the sides for better grip when turning.
The CPL & UV are clearly printed on the side without the grooves (in bright white letters)
CPL filter is a a bit thicker than the UV as it has a adjustable ring.
Perfect threading all the entire four piece.
The CPL & UV optical glass both have Nano coating that's keeps them waterproof and oil resistant.
Even when I put a nice big oily finger print on the glass, it was a quick wipe to clean.

Filter caps are in the K&F colors.
Black with a orange stripe.
Top cap also has logo in orange.

Storage.
When not in use the filter set is very compact at around .75" thick.
Place into the draw string storage bag.
A dark gray to black soft bag with a orange draw string with plastic ends.
Would easily fit in a pocket or placed into a gear bag.

Overall.
Applying and removing the filters from my lens was smooth.
For outdoor shooting both filters can be used at the same time.
Just as they said, no vigenetting or dark corners.
Circular Polarizer worked perfectly. Just turn until you get the glare is removed.
See photos of the bird bath.
This will permanently go into my gear bag. Recommended.
Hope this was helpful.
