Sirui CPL Nano Pro MRC (Aluminum) 82mm

Sirui CPL Nano Pro MRC (Aluminum) 82mm | Control reflections and sky tone

The aluminum frame gives this Sirui CPL a metal edge to turn as you adjust the polarising effect. CPL means circular polarising filter: it can reduce reflections and deepen the colour of a blue sky, with the result depending on the light and the filter’s position. That makes it useful for landscape photographers, and for anyone photographing water, glass or other reflective surfaces. It’s also a practical option when you want to manage those reflections in-camera rather than rely on editing later. The 82mm size is important when choosing one: it needs to match the filter thread on your lens. Sirui names this model Nano Pro MRC; the available product details don’t describe what those terms mean, so I wouldn’t read extra performance claims into them. If you’re comfortable adjusting a filter as you compose, this is a straightforward way to add polarisation control to an 82mm lens.

Using a CPL

Turn the filter while looking through the viewfinder or at the screen and watch how reflections and sky tone change. For water or glass, adjust until the unwanted reflection is reduced to the level you want; for a blue sky, the effect varies with your shooting direction relative to the sun. A CPL also reduces the light reaching the camera, so allow for that when setting exposure. The effect is adjustable, not an automatic finish.
