The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 35mm F1.4L II USM and the Leica Summilux-M 35mm f1.4 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. Canon EF 35mm F1.4L II USM is the longer of the two lenses at 106mm. The Leica Summilux-M 35mm f1.4 ASPH with a length of 46mm, is 60mm shorter. Besides being longer, the Canon EF 35mm F1.4L II USM also has a larger diameter of 80mm compared to the Leica Summilux-M 35mm f1.4 ASPH's 56mm 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. Leica Summilux-M 35mm f1.4 ASPH weighs 320g, 57% (440g) lighter than the Canon EF 35mm F1.4L II USM's weight of 760g.
Filter Threads
The Canon EF 35mm F1.4L II USM has a filter size of 72mm whereas the Leica Summilux-M 35mm f1.4 ASPH has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 72mm filters that we recommend you to consider for the Canon EF 35mm F1.4L II USM:
And these are the 46mm filters that we recommend for the Leica Summilux-M 35mm f1.4 ASPH:
