Yet I can think of a large number of people, myself included, who would pay quite a bit for a f/2 EF zoom if the image quality is good across the board. This would be a great street and portrait range on full frame, I'd reckon.Wahoowa said:

Even on APS-C it would be worthwile to get for street photography (in addition to indoor sports and portraits) since it would have 2 advantages over the 70-200 2.8 II - it's shorter and faster. Let's hope that it will be an L lens...

Think your slightly confused there.
If its EF-s then its 55 and 100mm lengths do not change when on a 7D or 60D (1.6x crop).
If on the other hand it was EF then your calculations make sense.
Secondly you rarely shoot video wide open, Usually if say your using a f1.4 you would set it to f2 or higher.
Basically wherever its sharpest and use the hyper focal length to work out best DOF ratio.

Right, I was referring to EF (since I am not familiar with EF-S lenses), however, in both cases the focal length would be shorter than my 70-200 f2.8 II and therefore be an even better street lens for me.
I am not a videographer, have not even tested the video capabilities of my 7D though it's in my possession for over a year... ;-)

If they can make that then perhaps they could make an EF 35-70 f2L now that would be pretty sweet

O, I missed that. There is a rumor about a 17-55 replacement? And the replacement will be f/2?
Those lenses must become heavy and big. I am not sure if that is so convenient while using them as walkaround / general purpose lens..... :-\
But 55-110 f/2 sounds great - as EF-s lens
EDIT: the 55-110 f/2 would be a great indoor sport lens with zoom capabilities

Actually, EF-S Lenses do also have to have their focal range multiplied by 1.6x to determine the 35mm equivalent. For example, the EF-S 15-85mm F/3.5-5.6 IS USM Lens has an effective range of 24-136mm, and the EF-S 17-55mm F/2.8 IS USM Lens has an effective range of 27-88mm. So, a proposed 55-110mm F/2 Lens, either EF or EF-S, would have an effective range of 88-176mm (not all the different from 70-200mm).
Personally, I'd love to see both an EF and EF-S revision so that the APS-C type owners can enjoy the benefit of a smaller lens - particularly on the Rebels.

DADDY LIKES
If they get this one right, I'll be all over it. I've been blabbing about the lineup needing a lens like this for a long time. Extremely pleased that they sacrificed a little extra reach for the extra stop of aperture that will set it apart from the competition. IIRC only Olympus offers an f/2 zoom up 'till now.
If it doesn't have IS, ring USM, and L-grade resolution I won't really see a reason to upgrade from my primes though; the 85 f/1.8 covers most of the situations this thing would. IS in a short fast telephoto is the game changer, not the zoom.
Now, what they really need is the same thing on the wide-angle side. I suppose that Canon thinks that the 17-55 f/2.8 fills the niche left by their arthritic non-L wide prime lineup, but this proposed telephoto's companion lens should really be something more like a 15-35 f/2 if they really want to talk about replacing primes with a zoom on the EF-s platform.

Sign me up for one along with a 17-55mm f2.0, I'm not holding out any hope now for new cheap primes, these will be the new cheap "primes" replacements. I still hold some hope that we might even get EF-S L lenses, the build quality of my 135mm f2.0 L is so much nicer than my "premium" 15-85mm EF-S
After the boredom of massive super expensive primes, I'm starting to get excited again :¬)

The half angle at the wide side is ~13.4 deg. If this was an EF lens, 55mm would be close to normal (= 47 deg), and the half angle would be >20 deg.
From the translation of the patent, it seems this design is intended for either 1.6x APS-C sensors or the new video cameras.

A 2.0 zoom won't be a poor man's anything. This thing will be large and heavy and expensive. If it's an L, it'll surely cost $2k or more. If it's EF-S, it'll easily be the most expensive EF-S available. If it's a Cinema lens I'll stomp and curse and spit.Blaze said:

if this lens really happens for aps-c, I would strongly consider it. I love primes, but can't afford to buy all of them in the 50-110 range. This lens would, if the IQ is there, replace all of them. i know it would be more expensive than the low end primes (not talking about the stratospheric L glass), but if it could replace all of them, I could make a strong family budgetary argument for it.
