The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander 28mm f2.8 Type I and the Canon 40mm f2.8 STM 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 28mm f2.8 Type I is the longer of the two lenses at 24mm. The Canon 40mm f2.8 STM with a length of 22mm, is 2mm shorter. On the other hand, the Canon 40mm f2.8 STM has a larger diameter of 68mm compared to the Voigtlander 28mm f2.8 Type I'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. Canon 40mm f2.8 STM weighs 130g, 9% (13g) lighter than the Voigtlander 28mm f2.8 Type I's weight of 143g.
Filter Threads
The Voigtlander 28mm f2.8 Type I has a filter size of 34mm whereas the Canon 40mm f2.8 STM has a 52mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 34mm filters that we recommend you to consider for the Voigtlander 28mm f2.8 Type I:
And these are the 52mm filters that we recommend for the Canon 40mm f2.8 STM:
Lens Mounts
The Voigtlander 28mm f2.8 Type I has the Leica M lens mount whereas the Canon 40mm f2.8 STM has the Canon EF lens mount. Some of the latest released cameras that are compatible with these mounts are Leica M EV1, Leica M11-D and Pixii Max for the Leica M Mount and Blackmagic URSA 12K LF, Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K for the Canon EF Mount.
Focal Range
Voigtlander 28mm f2.8 Type I is a prime lens with fixed focal lenght of 28mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of
42mm.
On the other hand, the Canon 40mm f2.8 STM is a prime lens with fixed focal lenght of 40mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 64mm.
