Is the sony fe 16 25mm f 2 8 g good on aps c?

On an APS-C body it works, but it stops being a wide lens. On a Sony a6400 it frames like 24-38mm, a standard range rather than the wide view that makes it appealing on full frame. The f/2.8 aperture gives about the depth of field of f/4.2 there, so it's easy to keep things sharp, but you won't get as much background blur as f/2.8 gives on full frame.

If you shoot APS-C and want wide, the landscape guide points to a wide zoom around 10-24mm on that sensor size. For the maths behind these crop numbers, see the aperture and depth of field section.
