52mm UV, CPL, ND4 Filtro Kit
The filter pouch is not very useful for storing filters as small strands of the materail ...
Used this on an EOS M2 with the EF-M 22mm and 18-55 lenses (using a step up ring for the 22mm). According to my not-too-rigorous testing, there is no visible degradation in image quality, but color cast should be expected (for example, the CPL disproportionately cuts out blue light). The CPL does filter out polarized light, as promised, and loses ~1.3 stops of light with unpolarized/randomly polarized light. The ND4 filter does blocks 2 stops of light, though my tests are far from precise.The filter pouch is not very useful for storing filters as small strands of the materail seem to fall off and get on the filter. It is also slightly too big and bulky. My canon lens cap does not clip on the CPL very well, but the lens cap that came with the filters does so perfectly. I did not try the hood, and there hasn\'t been any sun so far for flare tests.
