Ontario Gone: Mirrorless apsc have an innate advantage over full body apsc cameras: they can use speed boosters and get, essentially, very near FF image quality. More light equals a lower iso used per given scene which equals higher DR, less noise, and better colors. However, some people don't like the ergonomics of mirrorless. I personally think a mirrorless version of the K3 would be the perfect camera. Better than any FF on the market today. Keep the big grip, remove the mirror box, add sony's EVF, perfection.
Not exactly sure what a speed booster is, but Is there some kind of speed booster that you are aware of that would work with an apsc mirrorless like the pentax k01?
Aleo Veuliah: It is a good upgrade, many improvements, this way LightRoom continue to be the best, in my opinion Capture One the second and the third is the very good RawTherapy for FREE on windows also, and the fourth is Bibble Pro
Well done Adobe
RawTherapee is very good, but I would give Photivo a try. Photivo is free and a very powerful RAW editor with lots and lots of filters.
