The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica M 35mm f1.2 and the Leica Noctilux-M 75mm F1.25 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. Leica Noctilux-M 75mm F1.25 ASPH is the longer of the two lenses at 91mm. The Leica M 35mm f1.2 with a length of 50mm, is 41mm shorter. Besides being longer, the Leica Noctilux-M 75mm F1.25 ASPH also has a larger diameter of 74mm compared to the Leica M 35mm f1.2's 65mm 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 M 35mm f1.2 weighs 416g, which means it is 639g (60%) lighter than the Leica Noctilux-M 75mm F1.25 ASPH which has a weight of 1055g.
Filter Threads
The Leica M 35mm f1.2 has a filter size of 49mm whereas the Leica Noctilux-M 75mm F1.25 ASPH has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Leica M 35mm f1.2:
And these are the 67mm filters that we recommend for the Leica Noctilux-M 75mm F1.25 ASPH:
