This little clip would be great if it were adjustable or came as part of a set but it's use is limited to just one size of filter. The price is ok.

Using filters to produce better - or at least different - photos was essential in the days before digital photography made it very easy to add assorted effects 'in post'. So there are a lot of different sorts of filter out there, some more useful than others.Because 'exchangeable lens' camera lenses come in a variety of widths, so did the lenses.... and this is just for 52mm filters. All but one of my DLSR lenses turn out to be a different size to that, and the 52mm filter I have is a simple UV one, primarily used to protect your expensive lens.All my 'circular polarising' filters - ideal for reducing reflections on glass and water - and star filters - producing lovely effects on bright lights - and ND filters - to enable smooth water shots - and the rest... are not 52mm.So this is a good idea, but it would be even better if it was available for more than one filter size.
