What uv mirror does Canon 2470f2.8 match?

The polarizer can consider Marumi's latest HD series, provided that it is fake (cheap and good quality, 1500 or so). Compared with the previous generation, it is more anti-static and less anti-slip. At present, the light transmittance in the industry is the highest, and this CPL is thin and smooth, suitable for landscape photography. This CPL is not worse than the top of B+W. If it is for amateur use, it is recommended to buy Nyquist's ordinary CPL directly, just 200. As far as polarization effect is concerned, the actual imaging gap is not as big as you think, but the gap is not thin enough, transparent enough and anti-pollution enough. It doesn't matter if it is ultraviolet light. It is recommended to protect the mirror directly. Kengo's ultra-thin protective glasses, less than 200, are no different from 1000 (if not digital, buy L37 or L4 1).
