Panasonic GX850 vs Sony a5000

Below, we will be reviewing the Panasonic GX850 and Sony a5000, both Entry-Level Mirrorless digital cameras by competitors Panasonic and Sony. The image resolution of the GX850 (16MP) and the a5000 (20MP) is pretty well matched but the GX850 (Four Thirds) and a5000 (APS-C) use totally different sensor sizes.

The GX850 was announced 3 years later than the a5000 and that is quite a sizable gap as far as tech is concerned. Both the cameras come with the identical body type (Rangefinder-style mirrorless).

Before we go in to a complete comparison, below is a brief overview of how the GX850 matches up versus the a5000 with regard to portability, imaging, features and an overall rating.

For anybody who is going to carry your camera, you will have to factor its weight and size. The Panasonic GX850 enjoys outside measurements of 107mm x 65mm x 33mm (4.2" x 2.6" x 1.3") having a weight of 269 grams (0.59 lbs) and the Sony a5000 has specifications of 110mm x 63mm x 36mm (4.3" x 2.5" x 1.4") having a weight of 269 grams (0.59 lbs).

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you have at the time. Below is the front view overall size comparison of the GX850 compared to the a5000.

Looking at size and weight, the portability rating of the GX850 and a5000 is 90 and 89 respectively.

Generally, it is difficult to visualise the difference between sensor sizing purely by checking technical specs. The graphic below should give you a far better sense of the sensor measurements in the GX850 and a5000.

As you can tell, the 2 cameras posses different megapixels and different sensor sizing. The GX850 with its tinier sensor will make achieving shallower DOF harder and the Sony a5000 will give greater detail with its extra 4 Megapixels. Higher resolution can also make it easier to crop photographs somewhat more aggressively. The more recent GX850 is going to have an edge with regard to sensor innovation.
