Its time to look more closely at the Panasonic GX9 and Sigma fp, both Advanced Mirrorless digital cameras by brands Panasonic and Sigma.

Before getting right into a complete comparison, here is a quick introduction of how the GX9 matches up vs the fp with regards to portability, imaging, features and an overall rating.

This is a sample of the gallery pictures for Panasonic Lumix DC-GX9 & Sigma fp. The complete galleries are viewable at Panasonic GX9 Gallery & Sigma fp Gallery.

Often, it's difficult to see the gap between sensor sizing simply by checking technical specs. The graphic here might give you a greater sense of the sensor sizing in the GX9 and fp.

As you have seen, the two cameras provide different resolutions and different sensor sizing. The GX9 because of its tinier sensor will make getting shallower depth of field more challenging and the Sigma fp will give you greater detail as a result of its extra 5 Megapixels. Greater resolution will help you crop photos more aggressively. The older GX9 is going to be behind in sensor technology.
