What do you call the mirrorbox in a mirrorless camera?

Pretty much what the subject says. In a recent thread, I mentioned looking inside the mirrorbox. What would I say for an M or R series?

I was thinking along the lines of sensor compartment. I bring it up because "mirrorbox" is such a nice shorthand way to refer to it.

Hm, sensorbox?

Clearly, the correct answer is "Mirrorless box" 🙂

For the next question: What does the "S" stand for in RF-S lenses?

AFAIK, the sensorbox is the same size between the FF and APS sized sensors.

When EF-S was released some speculated it meant short back focus.

Although this should probably be a moved to a new thread, the "S" is simply Canon's way of maintaining labeling continuity for its lenses that are limited to APS-C optical coverage. i.e.: EF-S lenses for APS-C SLRs and RF-S lenses for the R7 and R10 or FF R cameras used in "crop" mode. The "S" designation refers to the size of the well-resolved optical field diameter, not the lens mount diameter or the "sensor box" size.

Canon has not defined the true meaning of "S", but internet "experts" have speculated it means "Short back focus" (clearly wrong since the back focus distance of EF and RF lenses is the same as that of EF-S and RF-S lenses), OR "Small image circle" which is more accurate, but is still just a guess.

I have heard of a definition, yet. I going to think of it as “small”, as in image circle size.
