Black Frames....

Hello

My K3II is producing random black frames.

Upon opening they actually have a data size, but no information.

I have not had a 'flappy' mirror.

Could it be a corrupt memory card?

Thank you.

All the best

Try changing the card,

And if the same happens after changing the card ... Does 'black frame' mean that a file is produced that can be read OK by your favourite software but all that is shown on the screen is black (i.e. RBG=0,0,0)? If so, (a) is the size of the file typical for the file type from that camera (try taking a truly black image for comparison); (b) what does exif data say the camera has done? Do black frames appear when using live view or OVF or both? Are frames black in raw or jpg or both? No specific ideas here, just trying to narrow it down if it isn't the card.

Good luck.

Thank you both.

I have been out this morning and suffered the same issue.

Whilst the data for the images is there (appropriate file size, shooting info etc) I have a black image on the screen.

It happens randomly.

I have tried three different cards...

Is it the same with RAW file?

Hi, I`m no expert with Pentax, but maybe write down any saved settings and do a camera reset to let it sort it out itself? It may clear up on its own, hopefully. I1ll keep my fingers crossed for you

Sorry, I should have added that these are RAW files.

I had something similar on a K1 a while ago which turned out to be a battery close to exhaustion. The battery was fairly old so was replaced with a new one and to date the issue hasn't returned.

That makes sense. Thank you.
