Is the canon ef 11 24mm f 4l usm good on aps c?

Yes, it works on APS-C, but it's not the lens I'd buy for that job. On an APS-C Canon the Canon EF 11-24mm f/4L USM frames like 18-38mm on full frame. That's a useful landscape range, but the 11mm end is only moderately wide, and you lose the dramatic sky-and-foreground look that makes a wide zoom worth having. f/4 also gives about the depth of field of f/6.4, which is fine for landscapes, where you'd stop down anyway.

If you already own one of these bodies, it's a solid pick. Good matches include the Canon EOS 90D, the Canon EOS 80D, and the Canon EOS 7D Mark II. If you're choosing from scratch, read the sensor sizes guide first to see how the crop changes your framing.
