Is the sony fe 24 240mm f 3 5 6 3 oss good on aps c?
Yes, it works well on APS-C if you want reach. On a Sony APS-C body it frames like 36-360mm on full frame, so one lens covers everything from wide street shots to distant wildlife. The trade-off is the aperture. At f/3.5-6.3 it gives about the depth of field of f/5.2-9.4, so you get less background blur, and it gets darker as you zoom. The stabilisation helps in dim light.
For an everyday kit, I'd pair it with an a6400 or an a6600. If video matters more, the ZV-E10 is the one to look at.
If the darker zoom aperture bothers you, the aperture section of the lenses guide explains what you gain with a constant-aperture zoom.
