I have been reading through this forum and trying to get a grasp on the Pentax cameras. I was recently shopping for a new DSLR, I was a Canon guy that transitioned to m4/3. That format doesn't seem to be right for me. I have tried, but the same reasons that drove me to it, are driving me away from it. Anyways, I happened upon the Pentax K-30. The specs seem great, and the look of it is also very nice. I see that there are plenty of lenses, at least for me. So onto the questions.
1. What is screw mount?
2. It looks like the K-30 has image stabilization?
3. Does Pentax K share a lens mount with any other manufacturer, similar to the Sony/Minolta?
4. What is the "WR" spec associated with the lenses?
Thanks in Advance
