Nikon lenses are more complicated than Pentax users recognize. If I understand correctly, many of them are screw-driven, and the D3xxx and D5xxx cameras lack in-body AF motor.
Also, they have the equivalent of aperture recognition problems, and someone who uses the wrong lenses with wrong bodies risks
physical damage, not just an incorrect metering.
