The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summarit-M 35mm F2.4 ASPH and the Voigtlander 28mm F2 Ultron 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. Voigtlander 28mm F2 Ultron is the longer of the two lenses at 51mm. The Leica Summarit-M 35mm F2.4 ASPH with a length of 34mm, is 17mm shorter. Besides being longer, the Voigtlander 28mm F2 Ultron also has a larger diameter of 55mm compared to the Leica Summarit-M 35mm F2.4 ASPH's 52mm 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 F2.4 ASPH weighs 197g, which means it is 47g (19%) lighter than the Voigtlander 28mm F2 Ultron which has a weight of 244g.
