I have to admit to having a soft spot for Pentax DSLRs; I've used them on and off for almost a decade, and have always found them capable and pleasant to shoot with. But one thing I really don't understand is their naming convention.
Effective in-body image stabilisation that works with every lens; Large; bright viewfinder is the best in class; Good contingent of external controls makes it easy to change settings
Relatively slow and clunky live view; In-camera JPEG processing needs a lot of twekaing for the best results; LCD screen isn't touch sensitive
