Canon rf 15 30mm f 4 5 6 3 is stm vs canon 16 28mm f 2 8?

I don't have a page for the Canon 16-28mm f/2.8 on this site, so I can't compare it fairly. I'd rather not guess at its specs.

Here's what I can tell you about the Canon RF 15-30mm f/4.5-6.3 IS STM. It's a full-frame zoom with image stabilisation and autofocus. It gets darker as you zoom in, which is typical of cheaper zooms. On APS-C it frames roughly like 24-48mm.

If the f/2.8 aperture matters to you, the Lenses guide explains how a constant wide aperture keeps exposure steady across the zoom and gives you faster shutter speeds in dim light. For wide landscape work, where you'll usually stop down to f/8 or f/11 anyway, the Landscape guide covers why f/4 zooms are a good choice. Tell me what you shoot, and I'll point you to the best fit from the lenses I do cover.
