Sorry, not shot with Pentax lenses or camera...

A couple of comments regarding the A7 series:
1) For wildlife I would consider the A7R for its higher resolution; allows more crop room and has good sensitivity. I have one and love it for wide-field astrophotography, nightscapes, landscapes and wildlife (but see #3).
See: A7R New Mexico album (Every picture in this album was taken with the A7R)
2) The above said, the A7S is probably the best option for darker locales but remember the resolution... I have an A7S on pre-order for astrophotography & nightscape photography.
3) None of the A7's have great autofocus with adapted lenses but focus peaking can make up for this if you're fairly proficient with manual lenses. I use a Sigma 150-500mm (Canon EF mount) w/ a Metabones III adapter on the A7R with reasonable success but normally use it w/ manual focus and focus peaking. I'm faster in this mode than is the autofocus! I also use the Sigma zoom on a Canon 60D which does have very fast autofocus.
See: A7R & 60D Ya Ha Tinda album
4) I like both the A7S and A7R (and the Canon 60D) but for different reasons and types of photography. In a lot of cases it is simply a personal choice as to which will serve the purpose best.
I can't comment on recent Pentax offerings. My latest Pentax is a 1970's era Spotmatic (35mm film).
