Panasonic GH5 has a
20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Panasonic GH4 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine IX processor.
Another difference between these two cameras is that Panasonic GH5's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the GH5 and GH4 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic GH5 and Panasonic GH4 Cameras
Panasonic GH5 and Panasonic GH4 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Panasonic GH4 has 26% larger pixel area (14.12µm 2 vs 11.16µm 2 ) compared to Panasonic GH5, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Panasonic GH5 and Panasonic GH4 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, GH5 has scored 77, 3 points higher than GH4.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic GH5
or the
Panasonic GH4 ,
including hyperfocal distance.
