It depends on the need. If you are mostly doing outdoors and landscape work Pentax K1 mk2 (or mk1) is a great camera (probably the best in full frame pro-am range).
Get the pentax 31mm f1.8 with would make for a great walk about camera.
Get the Irix 15mm blackstone for really great landscape shots and that works great for astrophotography.
I will probably be put on the stake for this by Canikons (rofl) for this. But I guess it is what it is...
Now replace all these cameras with ar15 family and this guy would become so bad ***...
