EOS R7 Grainy Image

[clickandcapture]

After switching from Fuji to Canon R7, it's very frustrating to see the image quality of this camera. I have used support rather not taking photos with handheld. The ISO was 400, even the image is so much grainy. Should I start planning to leave this Canon and again going back to my old buddy !!!

"All crop sensor cameras have a tendency to show noise much more than the larger sensor units, ....  It's all about pixel density."

I would put that statement solely in the opinion file category. It so infinitely difficult to compare two camera systems. Sensors are just one part of a complicated assortment of electronics that create a photo. High ISO is the factor that affects noise/grain the most. I can get crummy noise in my 4MP 1D. Huge photosites for sure.

I thought it appropriate to add my reference when making a comment about pixel density and noise to clarify my position.  Pixel density is but one factor, and I provide the following reference to cover the much wider gamut of contributing factors.  IMATEST article on Sensor Noise 

Imatest is a leader in image quality testing that has been headquartered in Boulder, Colorado since 2004. Imatest team members include a range of engineering disciplines including imaging science, computer science, physics, electrical, and mechanical engineering.

As I also commented, much depends on how one meters and exposes, and that takes a bit of getting used to for any new camera system or model.
