The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 12mm F5.6 and the Leica Elmarit-M 24mm f2.8 ASPH 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 Elmarit-M 24mm f2.8 ASPH is the longer of the two lenses at 45mm. The Voigtlander 12mm F5.6 with a length of 43mm, is 2mm shorter. On the other hand, the Voigtlander 12mm F5.6 has a larger diameter of 75mm compared to the Leica Elmarit-M 24mm f2.8 ASPH's 58mm 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 12mm F5.6 weighs 230g, which means it is 60g (20%) lighter than the Leica Elmarit-M 24mm f2.8 ASPH which has a weight of 290g.
Filter Threads
The Voigtlander 12mm F5.6 has a filter size of 67mm whereas the Leica Elmarit-M 24mm f2.8 ASPH has a 55mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 67mm filters that we recommend you to consider for the Voigtlander 12mm F5.6:
And these are the 55mm filters that we recommend for the Leica Elmarit-M 24mm f2.8 ASPH:
