Originally posted by vitalsax Pentax usa says redesign sensor, dpreview says revised sensor that was in the k20d. Since when redesign e revised means the same thing?
Since the sensor is essentially the same in the specifications we're given, I think it's a safe bet that they
do mean the same thing in this context. Since when are the adjectives in companies' self-promotional materials to be believed? (The classic example: how can something be both new
and improved?)
Honestly, I hope it's closer to "revised" — there's no sense in throwing the entire thing out and starting with a whole
new set of bugs. Rather than redesigning from scratch, a revised version can correct existing problems and make evolutionary improvements without taking a big risk of introducing new problems.
The Mozilla project is a classic example of this — when Netscape open-sourced their code, the original was deemed too messy to save, and everything was rewritten from scratch. This literally set the project back
years and the whole thing might have completely tanked if Firefox hadn't come along.
There's a good quote from
Joel Spolsky on this (emphasis his): It's important to remember that when you start from scratch there is
absolutely no reason to believe that you are going to do a better job than you did the first time.
