The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 28mm F2 Ultron and the Carl Zeiss Biogon T2,8/28 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 Biogon T2,8/28 ZM is the longer of the two lenses at 62mm. The Voigtlander 28mm F2 Ultron with a length of 51mm, is 11mm shorter. On the other hand, the Voigtlander 28mm F2 Ultron has a larger diameter of 55mm compared to the Carl Zeiss Biogon T2,8/28 ZM's 53mm diameter.
