Pentax X90 vs Sigma fp

Below, we will be matching up the Pentax X90 versus Sigma fp, one being a Small Sensor Superzoom and the latter is a Advanced Mirrorless by rivals Pentax and Sigma. There is a big difference between the image resolutions of the X90 (12MP) and fp (25MP) and the X90 (1/2.3") and fp (Full frame) use different sensor sizes.

Photography Glossary

The X90 was announced 10 years prior to the fp and that is quite a big gap as far as tech is concerned. Both the cameras come with different body type with the Pentax X90 being a SLR-like (bridge) camera and the Sigma fp being a Rangefinder-style mirrorless camera.

Before going straight into a comprehensive comparison, below is a brief highlight of how the X90 matches up vs the fp in the way of portability, imaging, features and an overall grade.

Often, it can be difficult to imagine the contrast between sensor measurements simply by reading specifications. The visual below might give you a far better sense of the sensor sizing in the X90 and fp.

To sum up, both of these cameras have got different megapixel count and different sensor measurements. The X90 using its tinier sensor is going to make getting shallower depth of field tougher and the Sigma fp will deliver more detail with its extra 13MP. Higher resolution will also let you crop shots much more aggressively. The older X90 is going to be behind in sensor innovation.
