Originally posted by mecrox Many thanks for all these excellent, helpful photographs. Although my head firmly says no - be sensible, stick with Pentax or maybe try a Canon FF - my heart is increasingly saying Go Sony and Zeiss. I don't know how much longer I'll be able to hold out without one or the other overheating ...

You have ti decide why you want to change makes, your talking Pentax VS canon FF your looking at 2 different systems you need to look at what lenses you have, if you have a variety of FF lenses from different manufactures which i have that why i brought a sony A7r so i could use them as they are meant to be used FF , Pentax does not have a FF yet and if they do in the future i would buy it as well , i can still use the A7r with my other lenses and the K511s and a Pentax FF with my Pentax lenses , Pentax cameras take just as good pic as any other brand , if you want long AF telephoto lenses you may change to Canon or Nikon as Pentax is a bit limited , there are many people who make a living shooting Pentax camera so it only the ability of the photographer be be able to get great photos from his or her gear .
