Sensor detailUK specification rounds effective resolution to 20.4 MP and total to 22.9 MP; maker US press release specifies 20.37 effective and 22.93 total. 5184×3888 single-shot output, separate from 80 MP tripod or 50 MP handheld pixel-shift compositesMaker specifies four-thirds CMOS, approximately 20.3 million effective and 21.8 million total pixels; native 4:3 stills 5184×3888. Sensor dimensions and BSI construction are not inferred from other Lumix bodies
Image formatsORF RAW and JPEG; high-resolution modes combine eight exposures and can save composite RAW; moving subjects and capture conditions affect resultsJPEG, RAW and RAW+JPEG; 4K Photo frames are separate cropped JPEG captures
ISO detailMaker UK published sensitivity range includes LOW, approximately ISO 80, through ISO 102400; default Auto upper limit ISO 25600. This headline range includes expanded settings, rather than implying ISO 80 is the native base sensitivityStandard stills ISO 200–25600; expanded ISO 100. Creative Video ISO 200–6400 with expanded 100, under the manual's mode restrictions
