Canon R50 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Fujifilm X-T50 has a
40.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS sensor and features X-Processor 5 processor.
Fujifilm X-T50's sensor provides 16MP more than Canon R50'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.
One other difference between these two cameras that is worth mentioning is that Fujifilm X-T50's sensor doesn't have an 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 R50 and X-T50 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R50 and Fujifilm X-T50 Cameras
As seen above, Fujifilm X-T50 has a 1.1x Larger sensor area than Canon R50. 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
Canon R50
or the
Fujifilm X-T50 ,
including hyperfocal distance.
