QI would like to invest in a new filter system. I am happy with my camera and three lenses, so would like to get a range of UV, ND and circular polarisers. I realise that this can be a costly activity, so will build my collection over time. My question is, should I go in for a square system like Lee or Cokin or should I buy individual screw-thread filters? I would like a system that is really good quality (no colour hue, etc.) as well as easy to travel with. Matt Nichols
AWhen it comes to filters, sometimes it’s best to use both screw-in filters as well as build a square filter system. To protect your lenses, invest in high- quality UV filters that you could leave on at all times to avoid dust and dirt sticking to the front elements.
Neutral density (ND) filters can be useful as full filters, as well as graduated filters, especially for landscape photography. A Lee filter system, for example, uses very highquality coatings, so there will be no colour cast to your filters.
Circular polarisers are one of the most expensive types of filters and a screw-in version (even a high- quality one) will be less- expensive than a square filter. If you would like adjustable polarity these normally need to be fitted to a square filter holder and can cost hundreds of pounds. Travel cases are available for both filter systems, although screw-in filters are normally smaller in size so may be slightly easier to pack when travelling.
