I compared my 2000d using the Canon Ef s 24mm with the m100 using the Canon ef m 22. The 24mm stops at 2.8 while the 22 goes down to 2.0 so for posterity I took photos using both 2.8 and 2.0 with the 22. The circles are different and there are tiny holes in the circles on the 2000d. I took a second photo but the holes are still there.. what are they? Oh and I just noticed at 2.8 the circles are taking on a hectogon shape on the m100.

It looks like 24 has more blur at 2.8 compared to the 22 at 2.8 is that because of the focal length difference?

Don't agonize over the math.
