Originally posted by mchud I want to see a difference, otherwise, why spend the extra money?
The money is going toward lots of things, not all of them directly related to IQ in small prints:
- more pixels to allow for larger prints and/or more cropping
- weather sealed body
- more controls on the body (two control wheels, more buttons, etc)
- more customizability of camera operation via menus
- shake reduction
- support for SDM lenses
- ability to work with a battery grip
- possibly better high ISO performance
- more external flash capabilities (although TTL is removed; that's one step backwards)
That's off the top of my head; I'm sure others could point out more. Lots of things that make the K20D the better camera, but not in ways that would directly affect small prints if you weren't needing to take advantage of those features.
Quote: So what you're saying, Marc, is that you won't notice a difference until you print over an 8x12. Up to that point it's going to look the same, but after that size I would?
As a rough generalization, sure. You'd also notice in smaller prints if you were taking advantage of SR, of course, or shooting with an SDM the DS wouldn't have worked with, or shooting at ISO 3200, etc. But mostly, it's better lenses and better technique that will make better pictures.
