The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 15mm f4.5 and the Leica SL 14-24mm 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 SL 14-24mm F2.8 ASPH is the longer of the two lenses at 131mm. The Venus 15mm f4.5 with a length of 48mm, is 83mm shorter. Besides being longer, the Leica SL 14-24mm F2.8 ASPH also has a larger diameter of 85mm compared to the Venus 15mm f4.5's 70mm 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. Venus 15mm f4.5 weighs 308g, which means it is 547g (63%) lighter than the Leica SL 14-24mm F2.8 ASPH which has a weight of 855g.
