OM System OM-5 vs Pentax K-01 Sensor Comparison
Oftentimes, it is difficult to visualize the contrast between sensor dimensions only by looking at specs. The pic below will help offer you a much better sense of the sensor dimensions in the OM System OM-5 and K-01.
As you can plainly see, both of those cameras posses different resolutions and different sensor dimensions. The OM System OM-5 because of its tinier sensor is going to make shooting shallower depth of field more difficult and the OM System OM-5 will resolve extra detail as a result of its extra 4 Megapixels. Greater resolution will also help you crop pics somewhat more aggressively. The more recent OM System OM-5 should have an edge in sensor tech.
