I've become so familiar with my K1Mii, that it's almost like an extension of my hand. The layout of dials and buttons just seems to fall under the right fingers, making it easy to adjust on the fly.
One thing not mentioned as a con. If you're in live view and manual mode it stops down to aperture setting. So in studio if you want to manual focus you have to rotate one click from manual to bulb then back to shoot. Or in auto focus use the view finder and half click. It's easy enough to work around but still it was flub by Pentax.
Couple of things I disagree with in the article. The earlier versions of LR produced some funky colors in pixel shift, but the later versions handle them just fine. As to ISO I'm getting much better results at higher levels. I can shoot up to 25,600 without an issue that can't be easily cleaned up in LR. At 51,200 I can still get a descent file and even at 102,400 I can get a useable image with a little editing. Some of that may be do to the fact that, when shooting high ISO I use a program mode that has High ISO Noise reduction, Highlight and Shadow correction activated.
