The preamble states, “Welcome to our Easter readings of the Amalgamated Newsletter to offset the effects of Covid.
“Ron Reynolds, President and of many hats for The Australian Photographic Collectors’ Society of Australia, contributes our one main article on the testing of lenses. It is a difficult topic that requires expertise to explain properly.
“George Dunbar of the Photographic Historical Society of Canada offers some of his finds in surfing the internet.
“Permissions granted: Back Focus – The Australian Photographic Collectors’ Society of Australia–Ron Reynolds; Photographic Historical Society of Canada–George Dunbar.”
Ron’s article is very detailed and of considerable interest. I did a similar test of various cameras and lenses in the late 1960s for members of the Bell Canada Camera Club in Montreal. Ron offers a far more detailed and precise analysis than my rather simple test results using a similar resolution test chart about a half century ago. George Dunbar submitted the May, 1941 Electronics magazine article. “Facsimile Speeds Air Reconnaissance” and the analysis article, “After the Shot Is Fired” from the March, 1931 issue of Science & Industry magazine.
