The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 40mm F2 SL II and the Carl Zeiss C Biogon T2,8/35 ZM 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. Carl Zeiss C Biogon T2,8/35 ZM is the longer of the two lenses at 55mm. The Voigtlander 40mm F2 SL II with a length of 25mm, is 30mm shorter. On the other hand, the Voigtlander 40mm F2 SL II has a larger diameter of 63mm compared to the Carl Zeiss C Biogon T2,8/35 ZM'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.
Filter Threads
The Voigtlander 40mm F2 SL II has a filter size of 52mm whereas the Carl Zeiss C Biogon T2,8/35 ZM has a 43mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 52mm filters that we recommend you to consider for the Voigtlander 40mm F2 SL II:
And these are the 43mm filters that we recommend for the Carl Zeiss C Biogon T2,8/35 ZM:
