The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Panasonic S 16-35mm F4 and the Leica 16-35mm F3.5-4.5 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 16-35mm F3.5-4.5 ASPH is the longer of the two lenses at 238mm. The Panasonic S 16-35mm F4 with a length of 100mm, is 138mm shorter. Besides being longer, the Leica 16-35mm F3.5-4.5 ASPH also has a larger diameter of 88mm compared to the Panasonic S 16-35mm F4's 85mm diameter.
