Is aps c good enough for professional work?

The site doesn't say whether APS-C is good enough for professional work as a general question. What I do cover is where full frame earns its extra size. My sensor guide says full frame matters for low light, events, and portraits with very shallow depth of field. For travel, street, and most hobby work, a good APS-C body with good lenses is enough, and you'll carry it more. It also says lenses and light matter more than the last stop of sensor performance.

So if your professional work is mostly one of those categories, APS-C can be a sound choice. If it's events or low-light work, full frame is the safer bet. Read Sensor sizes for the full reasoning. The full-frame bodies and lenses on this site, like the Canon EOS R6, are a good place to see what that path looks like.
