Olympus E-510 vs Pentax WG-1 GPS

Below, we are looking at the Olympus E-510 versus Pentax WG-1 GPS, one is a Advanced DSLR and the other is a Waterproof by brands Olympus and Pentax. There is a huge difference among the sensor resolutions of the E-510 (10MP) and WG-1 GPS (14MP) and the E-510 (Four Thirds) and WG-1 GPS (1/2.3") come with different sensor sizes.

The E-510 was unveiled 4 years prior to the WG-1 GPS which is a fairly significant gap as far as camera tech is concerned. Each of these cameras come with different body type with the Olympus E-510 being a Mid-size SLR camera and the Pentax WG-1 GPS being a Compact camera.

Before getting through a comprehensive comparison, below is a brief synopsis of how the E-510 grades against the WG-1 GPS in the way of portability, imaging, features and an overall score.

Generally, it is tough to picture the difference in sensor sizes just by seeing a spec sheet. The picture below will help offer you a more clear sense of the sensor dimensions in the E-510 and WG-1 GPS.

Clearly, both the cameras posses different megapixel count and different sensor sizes. The E-510 having a larger sensor is going to make getting shallower depth of field simpler and the Pentax WG-1 GPS will provide greater detail having an extra 4MP. Greater resolution can also let you crop images somewhat more aggressively. The more aged E-510 will be disadvantaged in sensor technology.
