Olympus TG-870 vs Pentax P70 Sensor Comparison

In many cases, it is very difficult to visualise the contrast between sensor measurements purely by reading through specs. The photograph here will give you a better sense of the sensor sizing in the TG-870 and P70.

As you can plainly see, both of these cameras have the same sensor dimensions but not the same megapixels. You can anticipate the Olympus TG-870 to resolve extra detail using its extra 4 Megapixels. Greater resolution will also help you crop images a bit more aggressively. The more modern TG-870 will have an advantage with regard to sensor tech.
