Is the tamron sp 24 70mm f 2 8 di vc usd g2 good on aps c?

Yes, it works well on APS-C, and it's a sensible pick if you want a fast standard zoom. On a Nikon F body it frames like a 36-105mm on full frame, and f/2.8 gives about the depth of field of f/4.2. On a Canon EF body it frames like 38-112mm, with f/2.8 giving about the depth of field of f/4.5. The crop makes it a little less wide, but the constant f/2.8 still keeps exposure steady across the zoom, which helps indoors and at events. If you're on APS-C, I'd pair it with a Canon EOS 80D, a Canon EOS 90D, or a Nikon D7500. For the reasoning behind a constant-aperture zoom as a first lens, see your first lenses and aperture.
