The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summilux-M 24mm f1.4 ASPH and the Leica Summarit-M 35mm f2.5 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 Summilux-M 24mm f1.4 ASPH is the longer of the two lenses at 59mm. The Leica Summarit-M 35mm f2.5 with a length of 34mm, is 25mm shorter. Besides being longer, the Leica Summilux-M 24mm f1.4 ASPH also has a larger diameter of 61mm compared to the Leica Summarit-M 35mm f2.5's 51mm 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 Summarit-M 35mm f2.5 weighs 220g, 56% (280g) lighter than the Leica Summilux-M 24mm f1.4 ASPH's weight of 500g.
