I have the 18mp leica Monochrom and have been noticing spots at the top corners of my images. Yesterday I was thinking it was just dust on the lens as it was quite dusty when I looked at it but I noticed the same spots from an image a moth or so ago. I also thought maybe it's just on the sensor but I can't tell anything obvious on the sensor under a light (but of course I understand that wouldn't rule it out. I'm attaching two processed images as that's what I have on hand right now and how you can see them the best.
Let me know what you think it could be. From what I can tell it's not the "sensor issue" but I guess it's possible. I have found sites showing what that should look like but haven't seen anything on what it would look like on the MM.
Thanks for looking!
