...we don't see anything in these images that makes me believe it is in fact a 2.8. ...

Based on the picture, the front element appears to be 75% of the size of the 58mm filter thread (~43mm diameter front element)

Compared to the existing 28mm f/2.8 which appears to be 70% of the smaller 52mm filter thread (~36mm diameter), it does seem to be indicative of a f/2.5 or f/2.2 for the new lens (42% larger area of front element).

EDIT: Additionally, using the same method of calculation the existing 28mm f/1.8 USM appears to have a 48mm element inside a 58mm filter thread (~82%).

that is indeed a decent way to make the connection, I know that length and other variables can also factor in the equation so I will keep my hopes up. but as you have put, it seems that 2.8 is indeed a fair assumption for the time being.
Canon XTi, AE-1 Program, Rebel II, Tamron 17-50 VC, Zenitar-M 50/1.7 and a bunch of other cheap lenses (50/1.8FD, 18-55 EF-S Kit, 35-70 Kit, 80-200 4.5-5.6). S100 classic.

hey,
 hope im wrong but imo the "24mm" and "28mm" is done is post, on blured ground. the structure of the lens should be visible the same as below/above - it isnt. besides, 24mm/28mm 2.8 with IS makes no sense whatever. the jpgs have embedded paths, which lookalike definitions of rendered lenses. and yeah both fonts look strange.

Maybe shopped by Canon but definitely shopped.

Holy crap, it's real!

The long drought of non-L primes is finally coming to an end!  Can't wait for the next 50mm f/1.4.  With IS, too?

I wouldnt say that stange, the two existing 2.8 primes at those focal lenghts didnt look to be selling well at all compaired to say the 35mm f/2 or the 50mm f/1.4.

Adding IS and potentially focusing on better performance at 2.8 does also allow them to seperate the market from the L's.

+1 on that. You can also search for wide primes like Leica or Nikkor, they also have 28 f/2.8 or 20 f/2.8 (without IS). I don't find it strange - especially combined with IS and capabilities of FF at high ISOs. And sure - they can now separate them from L's and still retain profit from them. If you really need fast lens - just look at 24 f/1.4L II.

Hope that RRP 800$ and 24 f/2.8 IS USM RRP 850$ will be around 700$ as street price.

Is the MSRP really $850 (for the 24) and $800 (for the 28)?  I feel like I'm taking crazy pills.  I don't think I'd be a buyer at even half those prices.

I agree with you completely. No way would I spend that on a 2.8 prime. If those turn out to be actual retail prices from Canon then I'll be really disappointed and it would be just another example of Canon's arrogance. I am getting tired of Canon's pricing when you look at the offerings from other makers. Canon are so much like Apple it's sickening.

Hopefully this is just the beginning of the refresh and we have a 35/2.0 28/1.8 USM IS coming our way.

I recently bought the 35 f/2. But will sell it if 35 f/2 IS hit the market

me as well.  there is no way I'm shelling out more than what you'd pay for a 50mm f/1.4 just to get an f/2.8 max aperture ... on a prime!  it's bizarre and very frustrating.  however, Sigma has been improving their lens quality (still nowhere close to L-series glass) so I'll be waiting to see if they take advantage of this opening in the FF prime lens market.  $800 for an f/2.8 wide prime?  really appalling.  it's not like this is a new 200mm f/2.8 IS we're talking about here.

What if it gets the same treatment and ends up being a $800 35/2.8 IS USM?

:-o

don't tempt fate ... but that looks like a distinct possibility at this point

Yippee something is happening!
It so about time.
I'm so desperate ..... pant, pant.
 ;D

1st• and most important 2.8 works for me ifBIG IF it is usable and that means not always hàving to step down to be sharp (1.8 doesn't do me any good if its not relatively  sharp). It seems as if many prime units are never used to the max because they start to suck.

2nd• I really really would like I.S.. I'm Shaky nice to meet you. It's in the genetics - it ain't age, ain't caffeine, can't blame sugar and no don't you dare mention my technique.

3rd• $$$$ glass in general seems a bit steep nowadays but like if I can stay at 2.8 with some good IQ well then OK.

4th• I most often hang out @ around 30mm/50mm being I'm  cropped.

Now about about a pre order........
7DII, 60D, t2i, Magic Lantern, Manfrotto, Joby, Domke, SanDisk and etcetera etcetera

Now that I've seen the prices for the 24mm and 28mm f/2.8 IS lenses, I most certainly do not want IS on the 50mm f/1.4 II.  They'd probably make it need 82mm filters and charge nearly as much as the 50mm f/1.2!   :P
