Ok so the first k-5 is on its way back to pentax for what I hope is replacement. It was just riddled with stains all over the sensor. Not only did it have the classic ribbon but had several others all with the halo around them.

I picked up a second body as backup. First it is certainly much cleaner then the first but there are a few spots that seem like they might be stains. They are located right at the bottom of the sensor one on the left and then another on the right with a couple of additional in the center but no ribbon stain.
I've included three cropped and an overall.

Any thoughts on these would be greatly appreciated. Before I jump the gun and return it I want see what others think.

Thanks
Kevin

use a actual sensor cleaning tool like the one pentax offers, or for some stubborn dust, you may have to wet clean it. Often camera stores offer to do this if you don't have a cleaning kit, or don't feel comfortable doing so.

Dust. I have a few spots like that on my K-5. Rocket blower won't get them off, nor will DR. I imagine a wet clean is what is required. I haven't done that yet...
