The type of photography that you are planning to use is an important decision factor. Here we have evaluated the ZEISS Loxia 21mm F2.8 and the Venus 24mm F14 2x Macro Probe 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. Venus 24mm F14 2x Macro Probe is the longer of the two lenses at 408mm. The ZEISS Loxia 21mm F2.8 with a length of 72mm, is 336mm shorter. On the other hand, the ZEISS Loxia 21mm F2.8 has a larger diameter of 62mm compared to the Venus 24mm F14 2x Macro Probe's 38mm 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. ZEISS Loxia 21mm F2.8 weighs 394g, which means it is 80g (16%) lighter than the Venus 24mm F14 2x Macro Probe which has a weight of 474g.
