All of the other filters in Lee’s range have an excellent reputation for optical quality, so there’s no reason to expect that its circular polariser should be any different in this regard – and it isn’t. The polarising effect is strong, and the high-end glass has no discernible effect on image quality and despite not being coated, it causes no problems with flare. As the filter is designed to attach to the front of the Lee filter holder, there is only one size available – 105mm. It needs to be this large to reduce problems with vignetting, but this amount of optical glass will never be cheap and at £218, it’s one of the most expensive polarisers out there. However, if you’re using it with the Lee system, you’ll only need to buy the one filter, rather than one for every thread in your lens collection. In terms of build quality, there is nothing to complain about. It’s well built, and rotates easily and smoothly. The not-so-good news is that it’s the thickest of the filters on test, which does create some problems with vignetting. Even at 24mm (on full-frame), the filter is visible in the corners of the frame and you really need to shoot above 26mm to avoid this problem. Although polarisers are not always at their best with ultra-wide lenses, it’s nice to have the option; and there are in fact, plenty of occasions when shooting ultra wide with a polariser does work well.
