Here are some more photographs taken with another vintage Pentax camera that I purchased of ebay on the 15th July 2012. The Pentax Spotmatic takes M42 screw-thread lenses and was introduced by Asahi in 1964, it was the first SLR camera to sell well with a through-the-lens (TTL) exposure metering system. The light meter is activated by pushing a small switch (which is on the left side of the lens housing) upwards.
This was a really good find being considerably clean and worked straight away when I put a new battery in it. All the shutter speeds work correctly, the self timer works and the viewfinder is clear. The photographs above were taken using an out of date (March 2000) Agfacolor HDC 200 35mm film.
