People keep complaining about Canon and Nikon sticking to lens-based IS;
your explanation below is a good reason, I think, for C&N to stay with the
in-lens IS, which works well (and can be tailored for the specific lens).
I shoot with a Canon 5DmkII and I know that Canon¹s IS lenses have made it
possible for me to do handheld photos, despite the fact that I am not very
steady anymore. I simply cannot get sharp handheld photos with a non-IS
system.
