you guys came up with all kinds of funny and not so suggestions..
for K-7s i'd make it like this:
externally I would change:
1.ISO button in some more convenient position;
2. Dual SD card slot and both fixed the ease of putting in and pulling out the cards;
3.Viewfinder magnification increased at least a bit would make it better
4.Articullating LCD or at least tilting LCD would improve its usability by much; that's very important to me personally..
internally i would change:
1. improve ISO performance to pretty easily usable 3200 ISO and sometimes usable 6400 ISO such change would make it the best seller all over the world.
2. Faster AF in low light and better AF-C
3. More options with HDR that's ability to have the raw file for later post processing.
4. video 60fps or more at least in 720p
5. more manual controls over video shooting.
6. x sync - 1/250 or at least a little better than 1/180 i'm gratefull for the current flash height in K7.
7. Time lapse recording for more than 99 shots...
I believe this isn't much.. and all is pretty achievable..
but it's very important to keep it externally of the same dimensions.. because it's perfect!
hope our messages will reach some influent minds..
