The Rensha Cardia is related to the Kalimar Action Shot 16 camera that I used in week 24. This one takes 8 shots in quick succession and uses a double width 35mm frame. It was originally marketed to golfers so they could analyse their swing.
In 2010 I decided to start taking photos with my collection of film cameras, using a different one each week. The project is now in its fifth year, and since May 2011 I have been writing a regular column about it in the UK magazine "Amateur Photographer".
