Moreover, both cameras have an APS-C sensor. Hence, the lenses they use are practically the same. So, when factoring in the weight, this is not an issue.

Canon M5 vs Pentax 3-K II Sensor Comparison

Both the Canon M5 and Pentax 3-K II have APS-C sized 24.0 MP resolution sensors so sensor size and resolution are the same between the two cameras.

However, one key difference is that the Nikon D5500’s sensor lacks anti-alias (Low-Pass) filter. This increases the sharpness and level of detail however it also increases the chance of a ripple effect in certain pictures.

As both the Nikon D5500 and Canon M5 have the same sensor sizes, they provide a good level of control over the depth of field when used with same focal length and aperture. However, the Pentax K-3 II has a 1.1x larger sensor area than the Canon M5. Larger sensors give you more control over the depth of field and blurry background compared to the smaller sensor when shot in same focal length and aperture.
