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 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 Voigtlander 28mm f2.8 Type I with a length of 24mm, is 27mm shorter. Besides being longer, the Voigtlander 28mm F2 Ultron also has a larger diameter of 55mm compared to the Voigtlander 28mm f2.8 Type I'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. Voigtlander 28mm f2.8 Type I weighs 143g, which means it is 101g (41%) lighter than the Voigtlander 28mm F2 Ultron which has a weight of 244g.
Below you can find the dimension and weight table of the Wideangle Prime Lenses in Leica M Mount for size comparison purposes.
