The bullet point differences with the two lenses are odd:

  • f/4L IS II got mention of a IS Mode 3, increased blade count, curved blades, etc. --> f/2.8L IS III did not

  • f/2.8L IS III got mention of ASC coating, internal focusing, etc. and the f/4L IS II did not

I'm sure the leaks are accurate at this point, but I'm guessing they are under-reporting feature information here.

And still no mention of the tripod ring being included or not (just a picture) or anything about the hood, a CPL window, etc.

The only major unknowns now would be:

  • MTF
  • The hood situation -- CPL window?
  • The tripod ring situation -- still included, or is selling it separately how they got the price down?
  • IS -- did we get Mode 3 like the f/4L IS II? Is it quieter for video?
  • Performance with teleconverters
  • Filter diameter -- 77 or 82?
  • Weight

Did I miss anything?

It is possible, they hide something. Look at the leaked images… the f4 is shown from the side, where you see all switches and the tripod ring. The f2.8 - from above. Minimum is revealed.
Well going to try to sleep now. Still hope for surprises tomorrow :)

UPD: I'm blind... this post have the picture from the side. Regular IS, regular tripod ring. No surprises.

3.5 stops? The II had 4 stops

There is now a CIPA standardized method for determining the effectiveness of IS/VC/etc., whereas there wasn't before. In general, manufacturer ratings are lower with the new standard.

I'd guess they improved the IS system on the f/4, and didn't change the IS in the f/2.8.

Looks like a good guess. See anything missing on the f/2.8L IS III that we've already seen on the f/4L IS II?

I'll give a hint with a close-up. I guess top of the line features don't always go on the top of the line lenses. :-[

All good, but I really would like the MTF! That is the key piece of the puzzle missing, everything else is frankly not a surprise, I mean what else could happen, its a lens...

I find it hard to believe that the photo posted today on the main page is the actual v3. It looks like a photoshopped version of a stock photo of the v2. It looks exactly the same as the v2, and usually Canon will at least make a slight design change.

The lack of specifics is also striking when we basically know everything there is to know about the f/4 v2. Maybe they're going to hold off on the v3 announcement for a while and just announce the f/4 tomorrow.

I agree. The f/4L IS mkI is internally zooming & focusing, I very much doubt the mkII doesn't.

I see no reason to upgrade from the current release lenses (f4L IS and f2.8L IS II) ...

By the way these are the characteristics they already had:
Canon 70-200 f2.8L IS II

-EF-Mount Lens/Full-Frame Format
-Aperture Range: f/2.8 to f/32
-One Fluorite Element & Five UD Elements
-Super Spectra Coating
-Ring-Type Ultrasonic Motor AF System
-Optical Image Stabilizer
-Internal Focus, Focus Range Limiter
-Weather-Sealed Construction
-Detachable, Rotatable Tripod Collar
-Rounded 8-Blade Diaphragm
-Optical Design 23 Elements in 19 Groups

Canon EF 70-200mm f/4L IS USM Lens

-EF-Mount Lens/Full-Frame Format
-Aperture Range f/4 to f/32
-One Fluorite Element and Two UD Elements
-Super Spectra Coating
-Ring-Type Ultrasonic Motor AF System
-Optical Image Stabilizer
-Internal Focus, Focus Range Limiter
-Weather-Sealed Construction
-Rounded 8-Blade Diaphragm


Already internal focus, already rounded blades, etc, etc...
