Whilst I have already published all those known things which are almost 100% certain at my Blog for tens days now, there are many other more important things about the K-7 which are still not yet known. So, based on what I have heard so far. Here they are:
Sensor: 14.6 to 15 MP new Samsung sensor - debugged version of the old one used in the K20D: Less Noisy, More Functions for LV and Movie
Metering System: New 77-segment 7x11 (Seven Eleven? ;->) equally divided metering system - more advanced
AF System: Still SAFOX VIII 11-point
AF hardware with tweaked
AF software algorithms and should respond faster and better at low light
WB System: New More Advanced and Accurate Auto
WB system and algorithms
HD Video: uncertain about 1920x1080 or 1280x720, no one talks about the frame rates concretely so far. (Whilst it is certain the Movie is there)
Viewfinder: 100% and 1.0X *Traditional* Optical Viewfinder
Any other things that you have heard that are "sensible"??
It seems that the leak-proof works of Hoya/Pentax have been doing very well this time, and we hear no more new news these few days! :-(
Maybe we have to wait until May 18 or 19, i.e., just a few number of days before May 21 that we can know more.. Too bad..
