50mm · f/3.5
The Canon FDn 50mm f/3.5 Macro is a sharp, distortion-free vintage lens, especially at f/8 where it's tack sharp corner-to-corner. Wide open at f/3.5, corners are soft, improving by f/5.6 but still not perfect. Build quality is solid metal or plastic, with a very long focus throw that suits deliberate macro work but not action. It achieves 1:2 magnification natively; an extension tube is needed for 1:1. Best for patient macro photographers on a budget.
