Kenko Filters
Kenko is a binocular and camera filter brand that makes solid filters for DSLR/Mirrorless and SLR cameras. They have roots in Japan and are the number one selling filter there. I was excited when they approached me and wanted to collaborate and sent me their UV and CPL filters to try out. The UV filter is essential in protecting that sweet lens glass. The polarizer changed the game, it got rid of nasty glares, created deep blue hues, and improved overall saturation.
