Olympus TG-870 vs Pentax WG-10

Its time to look a bit more closely at the Olympus TG-870 versus Pentax WG-10, one being a Ultracompact and the latter is a Waterproof by competitors Olympus and Pentax. The sensor resolution of the TG-870 (16MP) and the WG-10 (14MP) is pretty similar and both cameras offer the identical sensor measurements (1/2.3").

Usually, it's difficult to see the gap between sensor measurements purely by going over a spec sheet. The graphic below will give you a far better sense of the sensor sizes in the TG-870 and WG-10.

As you can see, both of those cameras come with the identical sensor size albeit not the same MP. You should expect the Olympus TG-870 to deliver greater detail as a result of its extra 2MP. Higher resolution will also allow you to crop photographs a good deal more aggressively. The more recent TG-870 is going to have an edge with regard to sensor innovation.
