I'm not sure yet because I'm not working on at home where I have comparison files but I think the noise from the IQ180 is better with C1 7 than it used to be.
Generally I don't go above ISO 200 (unless I go with Sensor+) but the last few days I've used ISO 400 a few times and it looks a bit cleaner than I remember. This might be because I'm using the back in cold weather (?) or it might be C1 7.
Anyone else seeing this?
