Sony A7 V has a
33.0MP Full frame (35.8 x 23.8 mm ) sized Partially-Stacked CMOS sensor and features Bionz XR2 processor. On the other hand, Fujifilm X-H2S has a
26.0MP APS-C (23.5 x 15.6 mm ) sized Stacked BSI X-Trans sensor and features X-Processor 5 processor.
Sony A7 V's sensor provides 7MP more than Fujifilm X-H2S'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.
Another similarity between these two cameras is that both Fujifilm X-H2S and Sony A7 V sensors lack anti-alias (Low-Pass) filters. 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 A7 V and X-H2S sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A7 V and Fujifilm X-H2S Cameras
As seen above, Sony A7 V has a 2.3x Larger sensor area than Fujifilm X-H2S. 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.
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
Sony A7 V
or the
Fujifilm X-H2S ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Full frame versus APS-C),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
