The camera is here. As far as I can see, there is a single decent-sized piece of dust on one of the internal ND filters and that's it. I cannot see any other marks on the camera's sensor assembly. The speck is big enough that I could imagine it being a little bit visible on a big blue sky, but in a way that'd be not hard to clone out. I'm also going to have to experiment with shaking the camera a little bit and/or blasting a rocket blower into the vent holes/fans. It's hard to imagine how that little sucker got in there. Worst case, if I decided to send it to CPS, I have to assume it'd be a pretty cheap repair.
Overall, I'll gladly trade that for the $1,500 price reduction vs new. 😅
