The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica Summarit-M 90mm F2.4 ASPH and the Leica Macro-Elmar-M 90mm f4 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 F2.4 ASPH is the longer of the two lenses at 67mm. The Leica Macro-Elmar-M 90mm f4 with a length of 41mm, is 26mm shorter. Besides being longer, the Leica Summarit-M 90mm F2.4 ASPH also has a larger diameter of 55mm compared to the Leica Macro-Elmar-M 90mm f4's 52mm 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. Leica Macro-Elmar-M 90mm f4 weighs 240g, 33% (120g) lighter than the Leica Summarit-M 90mm F2.4 ASPH's weight of 360g.
Filter Threads
The Leica Summarit-M 90mm F2.4 ASPH has a filter size of 46mm whereas the Leica Macro-Elmar-M 90mm f4 has a 39mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 46mm filters that we recommend you to consider for the Leica Summarit-M 90mm F2.4 ASPH:
And these are the 39mm filters that we recommend for the Leica Macro-Elmar-M 90mm f4:
Lens Mounts
Both the Leica Summarit-M 90mm F2.4 ASPH and the Leica Macro-Elmar-M 90mm f4 has the same Leica M lens mount. Some of the latest released cameras that are compatible with the Leica M lenses are Leica M11 Monochrome, Leica M11 and Leica M10.
Focal Range
Both lenses have the same focal range of
90mm but while Leica Summarit-M 90mm F2.4 ASPH has the fastest aperture of
F2.4, the Leica Macro-Elmar-M 90mm f4's widest aperture value is
F4.0.
