New Filters: Haida ND Set and Hoya Polarizer
Since October or November I own a Sigma 10-20 wide angle lens and since then I never had filters for that lens. This situation changed now, as better weather should be here soon. After some research I decided to buy the “cheap” Haida neutral density filters instead of much more expensive “real” ones. I had Haida ND filters before, and yes, they had some color casting. However, the ones I got now are the second revision (PRO II MC) and color casts should be better with these ones, at least some sources say.
