The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 50mm f/1.8 STM and the Canon 28-80mm 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 28-80mm f3.5-5.6 II is the longer of the two lenses at 71mm. The Canon EF 50mm f/1.8 STM with a length of 39mm, is 32mm shorter. On the other hand, the Canon EF 50mm f/1.8 STM has a larger diameter of 69mm compared to the Canon 28-80mm f3.5-5.6 II's 67mm 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 EF 50mm f/1.8 STM weighs 159g, which means it is 61g (27%) lighter than the Canon 28-80mm f3.5-5.6 II which has a weight of 220g.
Filter Threads
The Canon EF 50mm f/1.8 STM has a filter size of 49mm whereas the Canon 28-80mm 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 50mm f/1.8 STM:
And these are the 58mm filters that we recommend for the Canon 28-80mm f3.5-5.6 II:
Lens Mounts
Both the Canon EF 50mm f/1.8 STM and the Canon 28-80mm f3.5-5.6 II has the same Canon EF lens mount. Some of the latest released cameras that are compatible with the Canon EF lenses are Blackmagic URSA 12K LF, Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K.
Focal Range
Canon EF 50mm f/1.8 STM is a prime lens with fixed focal lenght of 50mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
80mm.
On the other hand, the Canon 28-80mm f3.5-5.6 II has a focal range of 28-80mm and 2.9X zoom ratio . When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 44.8 - 128mm.
