Sensor format decides the lenses, and the lenses outlast the body
A mirrorless body is the least permanent part of a system and the part people compare hardest. The decision that actually lasts is the mount, because the lenses bought against it will outlive two or three bodies, and the sensor format behind it — full frame, APS-C, Micro Four Thirds — which settles how much of each lens' image circle is used and therefore how a focal length frames. Resolution in megapixels is the number printed largest and the one that changes least in ordinary use; it decides how far a frame can be cropped and how large it can be printed, not whether it is sharp. Stabilization is quoted in stops and measured under a named protocol in a laboratory, with a focal length stated; where the protocol is not named, the figure is a claim rather than a measurement. The viewfinder is an electronic panel here rather than a mirror and prism, so its resolution and refresh rate are published specifications. Card slots matter to anyone who cannot reshoot the day: one slot or two, and the formats each one accepts. Then autofocus described by its published subject modes, the video resolutions and frame rates listed with any recording limits, and whether the body is sealed and to what claim. We compare sensor format and resolution, mount, stabilization claims and protocol, viewfinder specification, card slots, autofocus modes published, video modes and sealing.

24.2 MP, Dual Pixel AF II and a lens in the box.
26 MP, AI tracking, 4K120 and sensor-shift IS.
Choose the mount first; lenses outlast bodies.
The Sony a6700 does; the R50 listing names lens stabilization.
For most photography, yes; it keeps bodies and lenses smaller.
All three track subjects; the Sony adds a dedicated AI processor.
The Canon and Sony are; the Fujifilm offer is an import.
The LUMIX FZ80D moved to compact cameras: its lens is fixed.
Choose the mount, then decide between a kit to start and a body that grows.
