Ricoh GR Digital IV vs Sigma fp Sensor Comparison

More often than not, its tough to see the difference between sensor dimensions purely by looking at specs. The image here should provide you a more clear sense of the sensor measurements in the GR Digital IV and fp.

As you can plainly see, both of those cameras come with different resolutions and different sensor dimensions. The GR Digital IV featuring a tinier sensor will make achieving shallow depth of field harder and the Sigma fp will give you more detail due to its extra 15 Megapixels. Higher resolution can also allow you to crop shots a good deal more aggressively. The more aged GR Digital IV is going to be disadvantaged when it comes to sensor innovation.
