Panasonic GX85 has a
16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Panasonic FZ2500 has a
20.0MP 1″ (13.2 x 8.8 m ) sized BSI-CMOS sensor and features Venus Engine processor.
Another difference between these two cameras is that Panasonic GX85'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 GX85 and FZ2500 sensor size comparison.
As seen above, Panasonic GX85 has a 2.1x Larger sensor area than Panasonic FZ2500. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
