I think you are referring to Sony RX100 series (latest is version IV)
If you don't need to flexibility of changing lens, compact cameras using the 1" sensor give good quality images in a small package, examples are the Sony RX100 series, Canon G7X series, Panasonic TZ100.
I'm actually into Astrophotography. So would prefer a smaller camera that has interchangeable lens? Would like an all rounder to take on casual trips sometimes, instead of lugging the whole camera bag to a holiday hahaha.
