Is the sigma 24mm f 2 dg contemporary good on aps c?

Yes, it works well on APS-C, and I'd happily use it there. Because it's a full-frame lens, it crops down to about a 36mm view on an APS-C body, which is a useful everyday standard. The f/2 aperture gives roughly the depth of field of f/3 on that sensor, so you still get some subject separation. You won't get a wide-angle view, though. If you want wide on APS-C, look at a different lens.

It fits several Sony E-mount APS-C bodies, including the Sony a6400, Sony a6700, and Sony ZV-E10 II. For the sensor maths, see sensor sizes and the focal length converter. The full specs are on the lens page.
