The change from 16 to 26 Megapixel is not that big you might think. It's less than 30% increase per dimension. If you don't need these 30% and the resolution is the only reason to get a new cam you may think again.The new camera, (FWIW), is Fujifilm X-T30 II; it's got a APS-C 26 megapixel BSI-CMOS sensor. The old one is a Fujifilm X-T10, simply a older version but with "only" a 16 megapixel sensor.
