There was a camera show here in Toronto today I could not attend due to work, my brother scored on behalf a Pentax Spotmatic with a 55/1.8 and a 28mm wideangle for a steal. Now which battery should I get for the meter and where can I get a good source for lenses as I want a telephoto/portrait lens. I can thank my brother for this as he is a fan of his spotmatic and I hear the lens system is really good.
