Nikon DL24-500 has a 21.0MP 1 (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Expeed 6A processor. On the other hand, Panasonic G85 has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . Nikon DL24-500's sensor provides 5MP more than Panasonic G85's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the DL24-500 and G85 sensor size comparison.
As seen above, Panasonic G85 has a 1.9x Larger sensor area than Nikon DL24-500. 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.
