First Photos / Prevew Problems

richiet · 02-08-2017, 02:41 AM

I Have had my K50 for a couple of years and it has worked perfectly until this last week or two.

When I switch the camera on the first 2 or 3 photos are only just about visible.

If I press the shutter button 4 or 5 times the photos come out as normal and can be seen on the preview screen.

I have tried the reset function a couple of times but the problem still exists

I'm sorry to hear that. It sounds like your camera has the known aperture block failure that some cameras have. It's mostly common on K-30 and K-50. Just use the search function to search for "aperture block failure" and you will find lots of threads about this problem.
