The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 24mm F2 DG DN C and the Voigtlander Nokton 17.5mm F0.95 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. Voigtlander Nokton 17.5mm F0.95 ASPH is the longer of the two lenses at 80mm. The Sigma 24mm F2 DG DN C with a length of 72mm, is 8mm shorter. On the other hand, the Sigma 24mm F2 DG DN C has a larger diameter of 70mm compared to the Voigtlander Nokton 17.5mm F0.95 ASPH's 63mm 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. Sigma 24mm F2 DG DN C weighs 365g, which means it is 175g (32%) lighter than the Voigtlander Nokton 17.5mm F0.95 ASPH which has a weight of 540g.
Filter Threads
The Sigma 24mm F2 DG DN C has a filter size of 62mm whereas the Voigtlander Nokton 17.5mm F0.95 ASPH has a 58mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 62mm filters that we recommend you to consider for the Sigma 24mm F2 DG DN C:
And these are the 58mm filters that we recommend for the Voigtlander Nokton 17.5mm F0.95 ASPH:
Lens Mounts
The Sigma 24mm F2 DG DN C has the Leica L lens mount whereas the Voigtlander Nokton 17.5mm F0.95 ASPH has the Micro Four Thirds 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 OM System OM-3 Astro, OM System OM-5 II and OM System OM-3 for the Micro Four Thirds Mount.
Sigma 24mm F2 DG DN C is also available in the Sony E mount.
Focal Range
Sigma 24mm F2 DG DN C is a prime lens with fixed focal lenght of 24mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of
36mm.
On the other hand, the Voigtlander Nokton 17.5mm F0.95 ASPH is a prime lens with fixed focal lenght of 18mm which has an effective (full-frame 35mm equivalent) focal range of 36mm when used on a FourThirds format camera.
