Canon G7 X has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features DIGIC 6 processor. On the other hand, Hasselblad X1D has a
51.0MP Medium format (44 x 33 mm ) sized CMOS sensor .
Hasselblad X1D's sensor provides 31MP more than Canon G7 X'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 G7 X and X1D sensor size comparison.
As seen above, Hasselblad X1D has a 12.5x Larger sensor area than Canon G7 X. 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 G7 X and Hasselblad X1D sensors have been tested by DxO and the results show that X1D has a better overall score of 102, 31 points higher compared to G7 X's score of 71.
