Using the Cokin Filter System

Written by Andy Smale

I recently discovered that a 52mm A series adapter ring fits over the Holga lens beautifully. This makes using filters with your Holga incredibly easy. You will need to get a Cokin 52mm ‘A series’ ring, and a Cokin ‘A series’ filter holder.

Method

To attach a Cokin filter to a Holga slip the 52mm A series adapter over the end of the Holga lens as shown below. The Lens cap is 52mm and so the Cokin adapter will fit straight on without any problems, but is an interference fit so may be tight. Next add the Cokin filter holder. Finally add the Cokin filter of your choice.

Things to remember when using filters

All filters absorb some light so it’s better to use faster film, say ISO 400 and use filters to stop light entering the camera. Cokin publish the absorption values for their filters so these will give you a guide. Different colour filters will cause an individual effect on the final frame, and are most useful for changing contrast in black & white photography. Experiment to see what suits your style.

Note: using colour filters with colour film will result in your picture being the colour of the filter. If you are using colour filters, it may be best to stick with black & white film.
