The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 9mm F2.8 Zero-D and the Leica Summarit-M 90mm f2.5 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 Summarit-M 90mm f2.5 is the longer of the two lenses at 67mm. The Venus 9mm F2.8 Zero-D with a length of 53mm, is 14mm shorter. On the other hand, the Venus 9mm F2.8 Zero-D has a larger diameter of 60mm compared to the Leica Summarit-M 90mm f2.5's 55mm 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 9mm F2.8 Zero-D weighs 215g, which means it is 145g (40%) lighter than the Leica Summarit-M 90mm f2.5 which has a weight of 360g.
Filter Threads
The Venus 9mm F2.8 Zero-D has a filter size of 49mm whereas the Leica Summarit-M 90mm f2.5 has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Venus 9mm F2.8 Zero-D:
And these are the 46mm filters that we recommend for the Leica Summarit-M 90mm f2.5:
