When I shot my first portfolio for university applications in 1972 I used a Zenit B. This camera was a basic Russian brick of a camera with very few things that could go wrong. There was no meter. The Zenit E did have a matchstick style meter that one could refer to but this was not TTL. My father went mainstream in the late 1960’s and bought a Weston Master V, he gave me his Leudi Lite to use. I still have it and I still use it from time to time. As an average reflected light meter this works very well. I have compared it to my Sekonic, Minolta Spotmeter and Nikon TTL meters and I have to say the simplicity works very very well every time. Obviously it is limited but with slow films and selected shooting conditions it just works.
