The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sony FE 28mm F2 and the Leica Summicron-M 28mm f2 ASPH 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. Sony FE 28mm F2 is the longer of the two lenses at 60mm. The Leica Summicron-M 28mm f2 ASPH with a length of 41mm, is 19mm shorter. Besides being longer, the Sony FE 28mm F2 also has a larger diameter of 64mm compared to the Leica Summicron-M 28mm f2 ASPH's 53mm 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. Sony FE 28mm F2 weighs 200g, which means it is 70g (25%) lighter than the Leica Summicron-M 28mm f2 ASPH which has a weight of 270g.
Filter Threads
The Sony FE 28mm F2 has a filter size of 49mm whereas the Leica Summicron-M 28mm f2 ASPH has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
