Originally posted by LRNav Thanks again. I made certain my battery was fully charged as you suggested and fired off several shots with out any mirror flop. I then tried to load the firmware v1.21, But i was unable to un-zip the download from Ricoh. My usual double click did not work. Therefore when I attempted the upgrade it failed. I am using Windows 10 on my desktop and just can't adjust to Microsoft's so called improvements. My laptop is windows 7 so I will try it next.

yes make sure the batteries are fully charged.
Beside that, I'm not sure would the firmware update resolve your mirror flop problem, because I read it's a hardware issue. When I was buying my K3, I asked in shop the seller about this issue,
and he told me the serie with that issue is not longer available in their store, and they have the new K3 from factory and they resolve that in next serie.
I often use burst or continuos shooting, and I had no mirror flop issue yet, not even once...
But I hope, upgared firmware will help you, you never know !
