>>4405496>Chromatic aberrationDigicams were made for dirt cheap, so lenses there aren't perfect. They wouldn't use aspheric glass, but also they didn't have plastics and molds to make aspheric lenses out of plastic. Or maybe they did but didn't use it for that purpose, who knows. Due to size and cost constraints, you can't just put in more normal spherical elements to correct the aberrations.
>SharpnessExact same story.
>NoiseSensors they used back then were much more noisy.
>Image sizeThey didn't have 50 MP sensors you have in your phone right now. It was 2~14 MP.
