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.

Wow, this would be a fantastic lens to pair with a 7D for dimly-lit indoor sports. Sort of the poor man's crop version of a 1D + 70-200mm f/2.8 combination.

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.

This would be excellent as a portrait/street lens on a ff or 1.3

I could se this being an ef-s lens to be partnered up with the EF-S 17-55mm 2.8. That would be awesome. However price may be a bit too high and I think I would just save my money and put it towards the 1dx and use my 70-200 2.8. :)

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.

Bit of a bummer. If this is truly an EF-S lens, I'd much rather see it start at 40mm. The 70-200 on FF is versatile, and even used by landscapers because of this.

Obviously it would be quite large and quite pricey, but unless it's a Cinema lens a 7D + 55-110 f/2 would still be considerably cheaper than a 1D + 70-200mm f/2.8.

Which would I choose? A 1DX and a 70-200 f/2.8II or a 7D + 55-110 f/2? Hard choice give me a second  ;D ;D ;D

Other than the FD 55mm, I'm struggling to think of any "recent" use of the 55mm focal length in anything but an EF-S lens.

I've said before than an EF 40-140 f/2 would be the ultimate portrait and event-zoom, even an EF-S 55-110 f/2 would be a nice start.

Or just any zoom faster than f/2.8 would be nice...

indeed, it could be the 70-200 2.8 for apsc, I do like the idea, would be nice for events. In my opinion the 17-55 replacement would be rather 15-60 f2.8, perfect to be announced with the 7d2.

but give me the 650d first with less mp, new sensor, digic 5, 40d af (and microadjust) and a better viewfinder ;)
