K-5 iso issue
I just received my K-5 back from repair (CRIS) for an issue where images were sometimes not being saved to the memory card even though they would show up fine in the instant preview (full batteries, tried 4 different memory cards)... this happened on a few different occasions but usually images were saved. Since my warranty runs out beginning of June I decided to send it in for repair - that issue appears to be fixed (can't tell for sure as it didn't always do this).
After I got my camera back this evening I went through and set up all the menu options to my liking and then started taking some test pictures to make sure things were working fine. At first everything seemed good, until I started increasing the ISO. Pictures are fine at ISO 1600 and below, but anything above this and there is a major banding(?) issue... see pictures below. Also, the camera now doesn't even allow an ISO higher than 12800.
Has anyone else had similar issues? Most likely sending back for repair again tomorrow.
