Hi Morrighan, welcome to the list! The Spotmatic battery question Luigi mentioned may not be a problem, if http://www.photoethnography.com/ClassicCameras/index-frameset.html?index-bod y.html.html~mainFrame is right. There can be read: "Availability of batteries for the Spotmatic is better than other cameras of the era because the Asahi engineers built in a bridge circuit in the metering which makes it battery voltage independent. This means you can use the original 1.35 mercury PX400 battery, or a 1.5V silver-oxide replacement without problems. An exact fit PX400S is available, or you can use a #392 cell with a small rubber-O ring (purchasable at any fine home repair center or DIY store) as a spacer. I believe a #397 also fits as well."
I am curious about your pics and your way of seeing the world. BTW your name ... may I guess you come from Ireland? Best, Bernd
