Canon R7 Dust on the R7 Sensor

[Focus101]

First time experiencing sensor dust on on the R system. Had the R5 for 2 years and still clean even though I can be pretty forgetful and not turn the power off.
Today while out shooting wildlife, I spotted a big blob in the lower right corner. I reviewed my images and the spot appeared after about an hour of shooting and. I did not change lens in the field. I was using the EF100-400L. got home and look at the sensor and saw 2 big spots. Urrrrgh!!!! I did manage to dispatched the bigger spot with an air blower but there is a smaller stubborn one. Did some test shots. At f/8 it is barely visible but at f/11 is slightly more visible. It is in the lower right corner and most likely will not affect my shots since I usually crop my shots or it can be cloned out, BUT it is going to bug me because I know it is there! LOL!!!
How did that dust all of a sudden appear? Was it inside the camera or it fell from the lens. My guess would be that it fell from the lens, since that lens has been on that R7 for over a month.

Do you have Sensor Cleaner turned on? Some how my was turned off and six months later...well let's just say the bar top at a smokey, sticky neon bar was cleaner. If it's not turned on, the instructions are on page 798 of the Advance User Guide (1.8.0 or higher edition).

Sensor spots will rear their ugly little heads the smaller your Aperture as you have noticed and f/2.8 is not always the optimal solution. Sensor spots are a fact of nature and the only way to keep them to a minimum is Portrait Photography in a studio and only use a single lens.

Sensor Cleaner is on. when the spot is visible at f/5.6 that is not good because it will be more visible at f/11 when I use the 800mm f/11 lens. Yes, I am aware that the dust spots are more pronounce at smaller aperture. I'll be getting a sensor cleaning kit this week. I don't keep cleaning kits anymore. They usually dry out by the time I need it.
