My 645D recently took a turn for the worst when it started capturing images with no data. The image is completely black. At first I thought this may be an aperture block failure but after removing the lens, setting it to manual and 30 second exposure I was able to confirm a few things, firstly that it’s not a shutter sync issue, secondly that the shutter hadn’t failed, thirdly that the mirror was still lifting and lastly that it wasn’t an aperture block failure. Despite 30 seconds of exposure in a well lit room where I could clearly see the sensor, there was still no image. Curious if anyone else has experienced this on a 645D or any Pentax camera.
Some ideas:
And no errors on menu system, no digital filter or other oddities activated (reset?), is there/tested live view on this model?
Is file really no data ( 0 bytes) or like 20 mbyte black pixels? Other sdcard tested?
