I always like to imagine that this was the 'deal with the devil' that Pentax made in that past.
Sold off the future Pentax mirrorless to Samsung
Which is why Pentax has no proper response so far.
The NX series has been a nice system imo, the first with the EVF and SLR styling.
Good lenses catered for its mount (and aps-c) and a decent range of them to cover the most used focal lengths.
If I was to start from '0' and not cared for FF or future stuff (ie. no camera race, just taking photos as long as the the camera holds up), just a good set from UWA to short tele, this system would be it for me.
