I am currently on a 60d and unhappy with the ISO performance. Even at ISO 100 there is noise, but anything above ISO 800 is particularly unacceptable to me. Some of that noise can be cleaned up in Lightroom, but I'd like a camera with a less noisy sensor.
I was hoping the 70d would be a nice step up, but that doesn't really seem to be the case. So now I am considering a refurbished 6d.
For those 6d owners out there, what is the highest usable ISO setting for you?
Thanks for your comments in advance.
