Continual focusing

Somewhere I saw a list of canon lens can be changed in focal length continuously without losing focus. Does anyone have the link for this? Thanks!

Canon's "parfocal" (i.e., don't change focus when zooming) lenses are:

EF 16-35mm f/2.8L USM
EF 17-40mm f/4L USM
EF 24-70mm f/2.8L USM
EF 70-200mm f/2.8L USM
EF 70-200mm f/2.8L IS USM
EF 70-200mm f/4L USM
EF 75-300mm f/4-5.6 IS USM
EF 75-300mm f/4-5.6 III USM
EF 75-300mm f/4-5.6 III
EF 90-300mm f/4.5-5.6 USM
EF 90-300mm f/4.5-5.6

Discontinued lenses:
EF 17-35mm f/2.8L USM
EF 20-35mm f/2.8L
EF 28-70mm f/2.8L USM
EF 28-80mm f/2.8-4L USM
EF 50-200mm f/3.5-4.5 USM
EF 50-200mm f/3.5-4.5
EF 70-210mm f/4
EF 75-300mm f/4-5.6 II USM
EF 75-300mm f/4-5.6 II
EF 75-300mm f/4-5.6 USM
EF 75-300mm f/4-5.6
EF 80-200mm f/2.8L
EF 100-300mm f/5.6L
EF 100-300mm f/5.6

Thanks so much!!

Hrm.

If I am to believe the focus ring's distance indicator (and I am inclined to), then any FTM that doesn't move the indicator should be parfocal, no?

Notably, I don't think that either the 10-22 or 17-85 move the focus distance indicator whilst zooming, and both appear to be parfocal, in that I don't notice change in focus while zooming (tho with the 10-22, the dof is so great, that you never see much difference at all, for objects father away than a foot or so)
