The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon 50mm f1.2L USM and the Tamron 60mm f2 II LD IF Macro for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Tamron 60mm f2 II LD IF Macro is the longer of the two lenses at 80mm. The Canon 50mm f1.2L USM with a length of 66mm, is 14mm shorter. On the other hand, the Canon 50mm f1.2L USM has a larger diameter of 86mm compared to the Tamron 60mm f2 II LD IF Macro's 73mm diameter.
