Yes I know, a naff photo. Another day, another old lens. This time it is a Canon 50/3.5 macro. I know the history of this one because I bought it new in 1976 and over the years I have taken more photos with this lens than any other, by far. Thousands. I used it a lot as a working geologist, photos of outcrops, close ups,landscapes, drill core, mines, exploration camps, etc etc. Its been a lot of places.
