Pentax K100D vs Sony NEX-5 Sensor Comparison

Quite often, it is tough to envision the contrast between sensor dimensions just by reviewing specifications. The pic here should give you a more clear sense of the sensor sizes in the K100D and NEX-5.

Plainly, the two cameras have the same sensor dimensions but not the same megapixels. You can expect to see the Sony NEX-5 to offer you greater detail as a result of its extra 8 Megapixels. Greater resolution will help you crop images a bit more aggressively. The more aged K100D is going to be disadvantaged in sensor technology.
