My favourite of all the filters has always been the CPL. A vital piece of kit every landscape photographer should have and something which cannot be replicated in post processing. I rarely shoot without – it’s the perfect light manager. And let me tell you, Haida`s new M10 round “drop-in” CPL will never be off my lens.
I was curious to test if any slight vignette was present, and I can happily confirm that there is none at all, even pushing it through a tough test at my widest 16mm on a full frame camera. It gives amazing contrast, and cuts through some of the haze, especially on the clouds and the polarisation is visible in the sky producing some great detail. Removed almost all the unwanted glare and the see-through effect is well achieved on the water. Added some beautiful saturation which gives an overall instant pop to the image. Always remember with any filter – it brings into the equation a fourth dimension to the exposure triangle. With a CPL you will generally lose between 1-2 stops of light. As you can see in the comparison exif data below, I have lost around 1.5 stops.
Inserting the round “drop in” CPL into the M10 filter holder is the fastest I’ve ever used, never mind witnessed. It simply drops between the holder and lens creating a perfect seal from any stray light. It’s almost like gravity does the work for you – once you hear the click it’s locked in place. There is a three gear linkage design on the mount which rotates independently and very smoothly. Once you start turning the adjustable black dial which is centrally placed on the top of the filter, you’ll instantly see the polarisation intensity on your live view screen. I tend to always rotate a CPL 360 degrees first to check the availability of contrast, saturation, and reflection. The strongest effect takes place at an angle of 90 degrees from the sun, ie make sure your line of sight is perpendicular to the direction of the sun. The filter is easily removed or exchanged by gently squeezing the red plastic tabs on the top and lifting it out without disturbing your composition.
Constructed from high quality optical glass, each filter has ten layers of anti-reflective coatings, scratch-proof, provides the best clarity, includes the famous nano multi-coating to reduce reflection, waterproof (meaning any droplets of water literally roll off like beads, no ugly smears) and the dreaded fingerprints wipe off easily with a soft microfibre cloth.
I have to say how solid it feels, plus it’s very fast and easy to use. In the past, CPLs I’ve used can be fiddly, hard to screw on especially when it’s freezing cold, you’re up at silly o’clock waiting for sunrise and half asleep. Haida have really listened to their customers and produced this truly clever design making our life so much easier. It’s an absolute pleasure to work with.
The round “drop in” filters are available in a selection of: ND 0.9, 1.8 3.0, 4; CPL; Clear-night; GND-0.9 1.2; ND+CPL 0.9 and 1.8.
