Will a Pentax K-50 autofocus better and faster in dim light than a Nikon D3200?

In dim light, the auto-focus assist lamp will have to be activated so that the camera can focus on the subject in the scene.
Auto-focus speed is continually improving as technology improves.
Probably the fastest auto-focus camera now is the Nikon D810. Not only is it faster, but it is more accurate than any of the past cameras made by Nikon and they were super accurate.
If you are concerned about "better and faster", you will have to do some tests using different lenses with each camera. Some lenses auto-focus slower than others when mounted on the same camera body
You can expect the "entry level or economical" lenses to auto-focus slower than newer auto-focus lenses with "Silent Wave Motors" and internal focus (the lens barrel does not rotate as the lens focuses).
The newer the lens design, the faster the lens will auto-focus in general terms.
So basically, even with a camera known for rapid auto-focus capacity will be slowed based upon what lenses you use.
I don't know of any reason for one to be better than the other at autofocus. They both use the same contrast and phase detect schemes for autofocus.
I don't know the answer, but it is a good question. Some cameras are slower and/or less accurate at autofocusing in dim light. Autofocus assist lamps only help at short distances. Good side-by-side comparisons can be hard to find.
Most probably not.
They might be just the same. They're both low-level cameras.
Just turn the autofocus off and focus manually… I don't even use autofocus in good light… It helps my batteries last 3x longer than people who shoot with AF.
Pentax have just released the K-S1 just incase you fancy something different… You can see it on 'You Tube'.
