Both Canon SX60 HS and Panasonic GH4 have 16.0 MP resolution sensors but Canon SX60 HS's sensor is 1/2.3 (6.17 x 4.55 mm ) and Panasonic GH4's sensor is Four Thirds (17.3 x 13 mm ).
Since Panasonic GH4's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon SX60 HS.
Below you can see the SX60 HS and GH4 sensor size comparison.
As seen above, Panasonic GH4 has a 8.0x Larger sensor area than Canon SX60 HS. 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Canon SX60 HS and Panasonic GH4 sensors have been tested by DxO and the results show that GH4 has a better overall score of 74, 35 points higher compared to SX60 HS's score of 39.
