The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 28mm f2.8 Type I and the Leica Summaron-M 28mm F5.6 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 f2.8 Type I is the longer of the two lenses at 24mm. The Leica Summaron-M 28mm F5.6 with a length of 18mm, is 6mm shorter. Besides being longer, the Voigtlander 28mm f2.8 Type I also has a larger diameter of 52mm compared to the Leica Summaron-M 28mm F5.6'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. Voigtlander 28mm f2.8 Type I weighs 143g, which means it is 22g (13%) lighter than the Leica Summaron-M 28mm F5.6 which has a weight of 165g.
