The Canon 1Dx Mark II is an awesome camera in my estimation delivering super performance and image quality with one exception. I am experiencing what I consider to be unsatisfactory performance regarding spots on the sensor. I believe I have conclusively proven that the spots increase simply through camera usage indicating an internal issue with the body. The thinking is it may be related to the fast continuous frame rate possible. I am working with Canon and they have really worked hard replacing some components but we've not nailed it yet. It is not a problem at wider apertures because the spots don't show up, but I frequently shoot at f/11 and smaller and boy do they show up there. Since final use for many of my images is large prints (20x30; 24x48; & larger) there is no tolerance for any spots and much time is being spent in post production getting them out.
The closest camera in performance is the Nikon D5 so I'm wondering if any D5 shooters are seeing anything similar. If you've not noticed, could you do a test? Simply shoot a blank sky at f/11, f/16, f/22 and then use the "reveal spots" tool in Lightroom set at a modest 50% setting. Zoom in to 100% and look around the frame to see how many spots you have. Then after shooting a few hundred (or more) frames, do the same thing and see if you have an increase. If you're willing to share the images and send to me, I'll do the grunt work of counting spots and that would be great but not essential. I'm not looking to hammer Canon or Nikon but only seeking an explanation. As an engineer I like to be data driven and not jump to conclusions.
