Olympus E-M10 IV vs Pentax WG-1 GPS

Here, we are reviewing the Olympus E-M10 IV vs Pentax WG-1 GPS, one being a Entry-Level Mirrorless and the other is a Waterproof by rivals Olympus and Pentax. There is a crucial difference between the image resolutions of the E-M10 IV (20MP) and WG-1 GPS (14MP) and the E-M10 IV (Four Thirds) and WG-1 GPS (1/2.3") have different sensor sizing.

The E-M10 IV was manufactured 9 years later than the WG-1 GPS and that is quite a serious gap as far as tech is concerned. The two cameras feature different body design with the Olympus E-M10 IV being a SLR-style mirrorless camera and the Pentax WG-1 GPS being a Compact camera.

Before diving straight to a step-by-step comparison, here is a short overview of how the E-M10 IV scores against the WG-1 GPS in regards to portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Olympus OM-D E-M10 IV and Pentax Optio WG-1 GPS. The entire galleries are viewable at Olympus E-M10 IV Gallery and Pentax WG-1 GPS Gallery.

In case you're looking to lug around your camera regularly, you'll need to consider its weight and size.

Looking at size and weight, the portability score of the E-M10 IV and WG-1 GPS is 81 and 93 respectively.

In many cases, it's difficult to visualize the contrast between sensor measurements merely by going over a spec sheet. The visual underneath may give you a clearer sense of the sensor measurements in the E-M10 IV and WG-1 GPS.

Clearly, both of those cameras come with different resolutions and different sensor measurements. The E-M10 IV because of its larger sensor is going to make shooting shallower depth of field easier and the Olympus E-M10 IV will offer you greater detail due to its extra 6 Megapixels. Greater resolution will also allow you to crop photos a good deal more aggressively. The more modern E-M10 IV should have a benefit in sensor technology.
