Cokin P-series P164 £70, $105
for 77mm fitting
Cokin’s P-series range of filters is renowned for being sensibly priced and offering a wide range of effects, with some 140 creative filters to choose from. Most are square or rectangular, measuring 84mm in width, and mount via a P-series filter holder which costs around £12 ($15). Adaptor rings are available for lenses with attachment threads of between 48mm and 82mm, which cost about the same as the filter holder. The P164 circular polariser filter has a round design and fits into the rear slot of the holder. A knurled outer edge enables easy rotation.
The plastic holder feels flimsy compared with the Formatt-Hitech and Lee Filters holders, but this is reflected in the price. In our tests, we found a marginally warm colour shift along with a slight muddiness in darker areas.
The filter holder is relatively basic but enables the circular polariser to be used with additional filters
