My understanding... correct me if I am wrong.
1. Canon has gone through many (?) different versions of IS
2. The efs 17-55 IS has the latest IS
3. The 100-400 IS is an older version IS
4. Newer version of IS provides 1 or more additional fstops
If all of the above are true, is it possible for Canon to put the latest IS technology into their tele's and primes...could we see this possibly happening?

I think the current version of the 100-400 may have slightly better IS than its official 2 stops. I couldn't get a picture without shake blur with a Tammy 200-500, at 500 1/640s, not even at 1/800s, while I get 50% keepers at 400 1/45s with the 100-400 IS, provided the subjects) are static enough, of course
.
Of course the 70-200 F/4 IS has 4 stops, but it requires about 2 seconds of activation to work at 4 stops. The 3-stop version requires about 1/2 second, just like the first 3 stops with the 70-200 F/4 IS.
Kind regards, Wim
