The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF-S 35mm F2.8 Macro IS STM and the Canon 18-55mm f3.5-5.6 II 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. Canon 18-55mm f3.5-5.6 II is the longer of the two lenses at 80mm. The Canon EF-S 35mm F2.8 Macro IS STM with a length of 56mm, is 24mm shorter. On the other hand, there is no difference between the max diameters of these lenses, both coming at 69mm.
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.
Filter Threads
The Canon EF-S 35mm F2.8 Macro IS STM has a filter size of 49mm whereas the Canon 18-55mm f3.5-5.6 II 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 49mm filters that we recommend you to consider for the Canon EF-S 35mm F2.8 Macro IS STM:
And these are the 58mm filters that we recommend for the Canon 18-55mm f3.5-5.6 II:
Lens Mounts
Both the Canon EF-S 35mm F2.8 Macro IS STM and the Canon 18-55mm f3.5-5.6 II has the same Canon EF-S lens mount. Some of the latest released cameras that are compatible with the Canon EF-S lenses are Canon T8i, Canon 90D and Canon SL3.
Focal Range
Canon EF-S 35mm F2.8 Macro IS STM is a prime lens with fixed focal lenght of 35mm which has an effective (full-frame 35mm equivalent) focal range of
56mm when used on a APS-C / DX format camera.
On the other hand, the Canon 18-55mm f3.5-5.6 II has a focal range of 18-55mm and 3.1X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of 28.8-88mm when used on a APS-C / DX format camera.
