Thanks for your response and questions. It happens on all settings and stops. After snapping about 8 shots, it functions normally.
What is the fix for the aperture block problem? Is the repair shop mentioned offering service? Website or contact info.

Sorry you are having the problem which exists on both the K30 and K50. Take note of your Fstop. Does problem arise when at say 4.5? and no problem say at 18.0?
Some of the problems are when the lens is wide open or near wide open, and work okay at smaller lens opening (like mine did.) Maybe you are experiencing this.
If it works okay in manual mode, then you are having the dreaded aperture block problem.

I bought a K-50 in 2015. Yesterday, during my photography class, the same thing happened to me. Black or very dark photos. I finally got an image on the bulb setting after a 2 second exposure. I reset to factory default, took the lens off and on. Shot a number of photos on all settings. Then it suddenly worked. Tried taking photos inside again this morning with normal indoor lighting. Same problem. Adjusted settings again and after a few more shots, back to normal. Anyone ever discover what exactly is happening?

I sent mine out to CA, cost 100.00 plus shipping. The guy works on all different brands of cameras for about 20 years gives a year warranty.
google pentaxcamerarepair.com
So far, it been okay, about 2 months into repair.
I would set mine to sport mode, fire off about 5 - 8 shots, then it would work, turn off, then same problem.
There are people who repair the camera by filing down a "plunger". You can find this by searching, some good instructions.
Some had a slow degrade, while others when bad fast like mine, about 1200 shots.
