The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon RF 28mm F2.8 STM and the Canon 28mm f2.8 IS USM 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 28mm f2.8 IS USM is the longer of the two lenses at 52mm. The Canon RF 28mm F2.8 STM with a length of 25mm, is 27mm shorter. On the other hand, the Canon RF 28mm F2.8 STM has a larger diameter of 69mm compared to the Canon 28mm f2.8 IS USM's 68mm 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 RF 28mm F2.8 STM weighs 120g, which means it is 140g (53%) lighter than the Canon 28mm f2.8 IS USM which has a weight of 260g.
Filter Threads
The Canon RF 28mm F2.8 STM has a filter size of 55mm whereas the Canon 28mm f2.8 IS USM 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 55mm filters that we recommend you to consider for the Canon RF 28mm F2.8 STM:
And these are the 58mm filters that we recommend for the Canon 28mm f2.8 IS USM:
