Pentax WG-3 GPS vs Sony a5100

Let's look a bit more in depth at the Pentax WG-3 GPS versus Sony a5100, one being a Waterproof and the latter is a Entry-Level Mirrorless by competitors Pentax and Sony. There is a sizeable difference among the sensor resolutions of the WG-3 GPS (16MP) and a5100 (24MP) and the WG-3 GPS (1/2.3") and a5100 (APS-C) use totally different sensor measurements.

The WG-3 GPS was revealed 13 months before the a5100 which makes the cameras a generation apart from each other. Both of the cameras offer different body type with the Pentax WG-3 GPS being a Compact camera and the Sony a5100 being a Rangefinder-style mirrorless camera.

Before going straight into a full comparison, below is a short highlight of how the WG-3 GPS grades versus the a5100 with respect to portability, imaging, features and an overall rating.

The following is a preview of the gallery photos for Pentax WG-3 GPS and Sony Alpha a5100. The full galleries are viewable at Pentax WG-3 GPS Gallery and Sony a5100 Gallery.

In case you're intending to carry your camera frequently, you need to factor its weight and measurements. The Pentax WG-3 GPS comes with external measurements of 125mm x 64mm x 33mm (4.9" x 2.5" x 1.3") having a weight of 238 grams (0.52 lbs) whilst the Sony a5100 has proportions of 110mm x 63mm x 36mm (4.3" x 2.5" x 1.4") accompanied by a weight of 283 grams (0.62 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will differ based on the lens you select during that time. The following is the front view proportions comparison of the WG-3 GPS versus the a5100.

Considering size and weight, the portability rating of the WG-3 GPS and a5100 is 90 and 89 respectively.

Oftentimes, it is hard to envision the contrast in sensor sizing merely by viewing a spec sheet. The photograph here may provide you a greater sense of the sensor sizing in the WG-3 GPS and a5100.

Clearly, both of those cameras enjoy different megapixels and different sensor sizing. The WG-3 GPS having a smaller sensor will make achieving shallower depth of field more challenging and the Sony a5100 will provide you with greater detail because of its extra 8MP. Higher resolution will let you crop pictures far more aggressively. The older WG-3 GPS will be behind when it comes to sensor technology.
