The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 90mm F2.8 DG DN C 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. Sigma 90mm F2.8 DG DN C is the longer of the two lenses at 60mm. The Leica Macro-Elmar-M 90mm f4 with a length of 41mm, is 19mm shorter. Besides being longer, the Sigma 90mm F2.8 DG DN C also has a larger diameter of 64mm 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, 18% (55g) lighter than the Sigma 90mm F2.8 DG DN C's weight of 295g.
Filter Threads
The Sigma 90mm F2.8 DG DN C has a filter size of 55mm 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 55mm filters that we recommend you to consider for the Sigma 90mm F2.8 DG DN C:
And these are the 39mm filters that we recommend for the Leica Macro-Elmar-M 90mm f4:
Lens Mounts
The Sigma 90mm F2.8 DG DN C has the Leica L lens mount whereas the Leica Macro-Elmar-M 90mm f4 has the Leica M lens mount. Some of the latest released cameras that are compatible with these mounts are Leica SL3-P, Panasonic S1 II and Panasonic S1 IIE for the Leica L Mount and Leica M EV1, Leica M11-D and Pixii Max for the Leica M Mount.
Sigma 90mm F2.8 DG DN C is also available in the Sony E mount.
