Originally posted by lithedreamer Pixel Shift might be considered 'the primary upgrade', but I don't think it's fair to call KAF4 the primary upgrade. It was added in a firmware update, and currently only adds support for an updated version of a single lens, the HD 55-300 with PLM motor.
Both of those features are the reason I was (or am for the right price) looking for a K-3 II. I won't even bother looking at the K-3 due to it not having these features. I care not for a tiny, popup flash. I have cheap, wireless controllers and several full sized flashes that perform well.
The only reason I'm not jumping on the K-3 II bandwagon so hastily is I really want a flip screen and possibly the sensor (Dynamic Range) performance of the K-70 which I think will come in the K-3 II successor sometime next year... I'm guessing April/May/June. The K-3 II price hasn't really taken any significant decreases either. So the difference in price between K-3 II now and III then will probably not be that significant. Not that long from now.. for me anyway.
Plus the K-3 is discontinued. That ship has sailed.
