There has been some interesting discussion on another Forum regarding the k-50 being unable to function at ISO 3200.
I decided to experiment on my own, and was/am quite pleased at the way it turned out.
k-50 body with SMC Pentax-DA 18~55mmAL f/3.5~5.6AL Lens.
1/100s, f/5.6, ISO @3200, no flash and used Spot Metering Mode.
Thanks so much for viewing.
