The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sigma 10-18mm F2.8 DC DN C and the Canon RF 16mm 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. Sigma 10-18mm F2.8 DC DN C is the longer of the two lenses at 64mm. The Canon RF 16mm F2.8 STM with a length of 40mm, is 24mm shorter. Besides being longer, the Sigma 10-18mm F2.8 DC DN C also has a larger diameter of 72mm compared to the Canon RF 16mm F2.8 STM's 69mm diameter.
Below you can find a scaled side-by-side image of Sigma 10-18mm F2.8 DC DN C and Canon RF 16mm F2.8 STM to get a better idea of how their sizes compare in real life.
Comparison image of the Sigma 10-18mm F2.8 DC DN C and the Canon RF 16mm F2.8 STM Size and Weight 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 RF 16mm F2.8 STM weighs 165g, 35% (90g) lighter than the Sigma 10-18mm F2.8 DC DN C's weight of 255g.
Filter Threads
The Sigma 10-18mm F2.8 DC DN C has a filter size of 67mm whereas the Canon RF 16mm F2.8 STM has a 43mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 67mm filters that we recommend you to consider for the Sigma 10-18mm F2.8 DC DN C:
And these are the 43mm filters that we recommend for the Canon RF 16mm F2.8 STM:
Lens Mounts
Both the Sigma 10-18mm F2.8 DC DN C and the Canon RF 16mm F2.8 STM has the same Canon RF lens mount . Some of the latest released cameras that are compatible with the Canon RF lenses are Canon R50 V , Canon R100 and Canon R50 .
Sony E , Leica L and Fujifilm X mounts.
Focal Range
Sigma 10-18mm F2.8 DC DN C has a focal range of 10-18mm and
1.8X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of
16-28.8mm when used on a APS-C / DX format camera.
On the other hand, the Canon RF 16mm F2.8 STM is a prime lens with fixed focal lenght of 16mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 25.6mm .
