Ricoh GR IV HDF has a
26.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor . On the other hand, Canon T6 has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 4+ processor.
Ricoh GR IV HDF's sensor provides 8MP more than Canon T6'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 difference between these two cameras is that Ricoh GR IV HDF's sensor lacks 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 GR IV HDF and T6 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh GR IV HDF and Canon T6 Cameras
As seen above, Ricoh GR IV HDF has a 1.1x Larger sensor area than Canon T6. 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
Ricoh GR IV HDF
or the
Canon T6 ,
including hyperfocal distance.
