IMAGE COMPARISON

Camera Resolution with Digital Zoom

Digital Zoom at 2MP

Here you can see the writing on the trash cans - but somewhat blurred or "pixelated" at only 2MP.
Digital Zoom at 4MP

Here you can see the writing on the trash cans a little better - but still somewhat blurred or "pixelated" at 4MP.
Digital Zoom at 8MP

Here you can see the writing on the trash cans much clearer due to the higher resolution (more pixels) of the camera.
