Pretty solid, it compares well to the R5 at every iso except 100 where it is down a stop.
LESSON LEARNED FOR EVERYBODY: The day that I posted this thread was the day that I took delivery of this 90D from FEDEX. After I posted this tread I then logged onto CANON USA to register this camera. After several attempts to register this camera in both EDGE and FIREFOX, I called CANON USA Customer Service direct. That gentleman also attempted to register this camera for me, but again he had NO success. He then said let me put you on HOLD for a few minutes and check your S/N against a couple of corporate databases. He came back and said that this was an International model and NOT a CANON USA certified model. This was on a Friday afternoon and the Nationally Known Store; that I bought this from, was closed already. So Monday I called the Internet Salesman that I worked with; who insured me that this was a USA model being shipped, and all I got was is voicemail. So I called their 800 number and got right through to him and told him my issue. He send me an email with directions to ship this camera body back. It didn't include a shipping label where they paid the cost of return, but their shipping reference number was only valid for 7 days so I foot the bill to get this thing back to them. They received the camera back a week after it was initially delivered to me. I waited until the following Tuesday to re-engage with this company, and again I had to go through their 800 number to get this guy to answer. I asked for a status and he said that they didn't have ANY USA certified 90D models and that they were reimbursing me for the cost of the camera only, and then he hung up. I did a quick check of my bank account, and at least the deposit was there for the camera.
