The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tamron 10-24mm F3.5-4.5 Di II VC HLD and the Canon 18-55mm f3.5-5.6 IS 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. Tamron 10-24mm F3.5-4.5 Di II VC HLD is the longer of the two lenses at 85mm. The Canon 18-55mm f3.5-5.6 IS STM with a length of 75mm, is 10mm shorter. Besides being longer, the Tamron 10-24mm F3.5-4.5 Di II VC HLD also has a larger diameter of 84mm compared to the Canon 18-55mm f3.5-5.6 IS STM's 69mm 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 18-55mm f3.5-5.6 IS STM weighs 205g, 53% (235g) lighter than the Tamron 10-24mm F3.5-4.5 Di II VC HLD's weight of 440g.
Filter Threads
The Tamron 10-24mm F3.5-4.5 Di II VC HLD has a filter size of 77mm whereas the Canon 18-55mm f3.5-5.6 IS STM 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 77mm filters that we recommend you to consider for the Tamron 10-24mm F3.5-4.5 Di II VC HLD:
And these are the 58mm filters that we recommend for the Canon 18-55mm f3.5-5.6 IS STM:
Lens Mounts
Both the Tamron 10-24mm F3.5-4.5 Di II VC HLD and the Canon 18-55mm f3.5-5.6 IS STM 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.
Tamron 10-24mm F3.5-4.5 Di II VC HLD is also available in the Nikon F (DX) mount.
Focal Range
Tamron 10-24mm F3.5-4.5 Di II VC HLD has a focal range of 10-24mm and
2.4X zoom ratio which has an effective (full-frame 35mm equivalent) focal range of
16-38.4mm when used on a APS-C / DX format camera.
On the other hand, the Canon 18-55mm f3.5-5.6 IS STM 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.
