The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 50mm F2 C and the Voigtlander 50mm F1.5 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. Sigma 50mm F2 C is the longer of the two lenses at 70mm. The Voigtlander 50mm F1.5 with a length of 46mm, is 24mm shorter. Besides being longer, the Sigma 50mm F2 C also has a larger diameter of 70mm compared to the Voigtlander 50mm F1.5's 54mm 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. Voigtlander 50mm F1.5 weighs 293g, 15% (52g) lighter than the Sigma 50mm F2 C's weight of 345g.
Filter Threads
The Sigma 50mm F2 C has a filter size of 58mm whereas the Voigtlander 50mm F1.5 has a 49mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 58mm filters that we recommend you to consider for the Sigma 50mm F2 C:
And these are the 49mm filters that we recommend for the Voigtlander 50mm F1.5:
Lens Mounts
The Sigma 50mm F2 C has the Sony E lens mount whereas the Voigtlander 50mm F1.5 has the Leica M lens mount. Some of the latest released cameras that are compatible with these mounts are Sony FX5, Sony A7R VI and Sony A7 V for the Sony E Mount and Leica M EV1, Leica M11-D and Pixii Max for the Leica M Mount.
Sigma 50mm F2 C is also available in the Leica L mount.
Focal Range
Both lenses have the same focal range of
50mm but while Sigma 50mm F2 C has the fastest aperture of
F2.0, the Voigtlander 50mm F1.5's widest aperture value is
F1.5.
