The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 50mm f/1.8 STM and the Carl Zeiss Planar T1,4/50 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. Carl Zeiss Planar T1,4/50 is the longer of the two lenses at 69mm. The Canon EF 50mm f/1.8 STM with a length of 39mm, is 30mm shorter. On the other hand, the Canon EF 50mm f/1.8 STM has a larger diameter of 69mm compared to the Carl Zeiss Planar T1,4/50's 66mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Canon EF 50mm f/1.8 STM weighs 159g, which means it is 191g (54%) lighter than the Carl Zeiss Planar T1,4/50 which has a weight of 350g.
