Mine does not say Serenar on it...
Maybe mine is older..
Will the serial number tell me anything?
The Serenar came before the later lenses that are just marked Canon. Check Peter Kitchingman's site for a lot of detail onthis and all the rest of the Canon lenses. The last Canon lens is one of the black/chrome type, later and much larger. The Serenar is a 34mm front, the Canon is 40mm. The small Canon was produced after this, but before the new mount, with bigger glass, but no design change. Details also available on the Canon Museum site, which does have some less than accurate information here and there. I believe it's corrected when it's found, and it does have other interesting features.
Canon used different series of numbers, rather than the Leica system. That makes tracking age by the numbers a guessing game. Yours is one of the newer lenses, but they both shared the same design. The 2.8 was the last, and again was one of the newest, larger lenses.
The earlier 3.5 is VERY compact, and is ideal on one of the Barnack style cameras. I use mine on everything from a Canon IV-Sb2 to a P, and a Leica IIIa and IIIf. Makes them all pocket size. The P is most convenient, because the finder is built-in.... and the back opens. It took Leica years to learn about that (please, no rock throwing, you Leica owners know that is true).
