I'll just add a 4.1 to Pat's list. Some lens have "automatic panning detection", so there is multi-mode IS, but it is not user selectable.

I didn't know that, but I was just sitting here wondering if such a thing existed. So it would probably be looking for large amplitude movements with relatively small rates of change over time... and when detected, then switch to pan mode???
I do not know if I like giving up that control, but it would be useful for that spur of the moment bird shot where I always forget to flip the switch or do not have time too.

Lens-based IS does not and cannot have correction for roll – the lens elements are round, rotating them would not change the image. Only sensor-based IS can correct for roll.
Indeed. In fact, when the EF-S 18-55mm f/3.5-5.6 IS was updated to the MkII version (prior to the STM), the lenses were identical except for some cosmetic changes (labeling font, a silver ring made black, mount registration mark painted instead of embossed), and the addition of automatic panning detection to the IS system.
What you say makes sense, and I do not doubt you. I got that from and article I read when I was trying find out how many axis they actually sense, and I admit I did not think about their answer enough to question its accuracy.
Got the information from: http://www.brayebrookobservatory.org...OIS_M%26M.html
Quoting:
"The lens-based OIS designed by Canon initially compensated for pitch & yaw. Their latest OIS can in a few specific lenses also compensate for either roll (limited rotation - angle movement in pitch but also simultaneous side to side), pitch & yaw (Hybrid IS), or pitch, yaw & piston"
Thanks for setting the record straight.

Reading over that article, it appears the author misconstrues the functions of Canon's Hybrid IS, or that they simply don't understand what 'roll' actually is...
Quoting:
"During the summer 2009 Canon announced roll compensation in some of its forthcoming mid-range telephoto lenses."
That was the announcement of the EF 100mm f/2.8L Macro IS, and Canon certainly did not say or even imply correction for roll. Hybrid IS adds correction for 'shake' (translational motion in the X and Y directions) to the typical corrections for angular motion (pitch and yaw).
The 5 axes are:
In a nutshell, sensor-based IS can correct up to all five, lens-based IS can correct up to four (excluding #5).
