Originally posted by smiechoo The biggest avantage K10D offers when compared to K200D is bigger/ brighter viewfinder - pentaprism vs. pentamirror, it is the main reason I am switching from K100D to K10D.
Other issues included in the thread already are easier control of different functions in case of K10D, and K10D drawbacks: bigger size/ weight and the proprietary battery.
Good luck with your choice
I've had my K100D a little over a year now, and I've been satisfied with the viewfinder thus far. In fact, the viewfinder has never been an issue with me.
If the K10/K20D's viewfinder is that much brighter, (and I do believe everyone who's said so) it must be fantastic!
I could probably swing a K20D right now, but I'd rather bulild a slightly larger collection of good glass before I upgrade the body.
4 days left for that $100 rebate on a K20D body...
