shooting at 30 secs

I have a k-50, every time I try to shoot with a shutter speed of 30 second, I have to restart my camera. It sort of falls a sleep. Why?

The camera is exposing for 30 seconds so make sure you are waiting long enough.
Also if you have slow shutter speed noise reduction setting ON it may be doing post processing before it gives back the display to you.

Yes, that's slow speed noise reduction. It works like this: It takes another exposure of about 20 or 30 seconds with the shutter closed. So you have to wait for this. Then it finds the noise in that second exposure and removes it from the first exposure.

See page 100 of the K-50 manual for details. You can turn it off in the [Rec. Mode 3] menu, second item, [Slow Shutter Speed NR].

When this is enabled, the camera is turns on the sensor without opening the shutter, for the same time as your shot's shutter speed. The image should be totally black but has some noise from the sensor. The camera subtracts the dark frame from your image, so your image has less noise. But it's an annoying thing to wait for.
