The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Noctilux-M 50mm f0.95 ASPH and the Fujifilm 35mm F1.4 R 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 50mm f0.95 ASPH is the longer of the two lenses at 75mm. The Fujifilm 35mm F1.4 R with a length of 55mm, is 20mm shorter. Besides being longer, the Leica Noctilux-M 50mm f0.95 ASPH also has a larger diameter of 73mm compared to the Fujifilm 35mm F1.4 R'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. Fujifilm 35mm F1.4 R weighs 187g, 73% (513g) lighter than the Leica Noctilux-M 50mm f0.95 ASPH's weight of 700g.
Filter Threads
The Leica Noctilux-M 50mm f0.95 ASPH has a filter size of 60mm whereas the Fujifilm 35mm F1.4 R has a 52mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 60mm filters that we recommend you to consider for the Leica Noctilux-M 50mm f0.95 ASPH:
And these are the 52mm filters that we recommend for the Fujifilm 35mm F1.4 R:
