AI Subject Detection tracks birds and aircraft with reliability that full-frame alternatives struggle to match
Handheld High Res Shot produces 80MP images from a 20MP sensor using IBIS movement
IP53 weather sealing withstands heavy rain and dust — the most rugged mirrorless reviewed

20MP M4/3 sensor — lower resolution and weaker low-light than full-frame alternatives
M4/3 system requires smaller lenses which limits the very largest apertures
