>>4486035K1ii feels like it can take pics in the dark especially with the FF sensor it just eats at <3200 ISO.
KF/K-70 was pretty damn good too. This is at 12800 ISO and one of my favorite pics. Pentaxes are very ISO-agonstic imo...its the garbage AF + not-screw drive lens selection + horrible support that kills them.
I regret selling my KF for $380 honestly kinda wish I just kept it, kinda shopping for another one <$300.
