Pentax is doubling down on the Q (as well they should). A near "Q" with an AF K-mount and this range of normal lens is going to be awesome.
It is the perfect time to make people take another look (beyond their prejudices) at the original Q model (now selling for $399) and then this one.
The small sensor gives you all kinds of advantages with its extremely high DOF, especially for macro. If this is a Q with an autofocus K-mount then Pentax is going to sell a million DFA 100mm Macros to go with it.
On a Q sensor that gives you the whole bug in focus (not merely a slice) and at the other end it gives you a 560mm super telephoto (all in one lens).
The thing they are going to have going against them is all the people who still don't "get" the Q.
This guy certainly gets it.
This camera is using a slightly larger Sony Exmor-R than the Q has...1/2.8"
Think iPhone's sensor only much larger.
