Maybe there have been other pictures online while you posted that, but I do see some differences there, besides the "4" and "8". But as it's been only 5 minutes ago, I'd suggest to take another look at them. ;)

Canon has needed to update their selection of non-L primes for a while now, and these seem to be a good start. I think that these IS lenses would be good for all sorts of outdoor use such as hiking without a tripod. It's often necessary to stop down for dof in low light. If the IQ is there, and the price and weight are low, I think these will be a great addition to any camera bag. There are already faster lenses in these lengths.

Comparing the picture of the new lens to the existing 24mm f/2.8 shows that both use a 58mm filter and the front elements are the same size ~43mm. I would assume, then, that the new lens would have the same aperture as the old lens.

For comparison, the 24mm f/1.4L II USM has a 77mm filter thread and a front element with a diameter ~50mm.

I find that very hard to believe in reality - the lenses would seemingly need to be more different, if only that it would be next to impossible to take photographs of two products that were the same in every way (reflections, etc) except for two numbers.

Has anyone loaded both of these into photoshop and done some pixel peeping?

I suspect that one of these two is real and the other is not.

nope the 24 is longer and has a larger focus ring and different focus scale.
as is to be expected.

Are we sure this is an EF lens? Aren't the ones with the silver taping EF-S? Would make sense for IS then, if it's a marketing tactic aimed at folks with entry level / prosumer bodies.

The mount marking on this lens is for EF (red). The mount marking for EF-S lenses is white.

The release of the 24 and 28 f/2.8 IS USM lenses provide us an insight into what Canon is planning: compact FF. I will not be surprised if Canon releases mirrorless or Rebel-like FF some time this year.

I like the way you think.


As for the comments about the silver ring:
75-300mm III has a silver ring (1999) -

90-300mm had it too (2003) -

28-90mm III as well (2004) -

Canon attempted to differentiate lenses with USM by using the gold ring (see 17-85mm, 70-300mm IS non-L, 10-22mm, 17-85mm) regardless of mount (EF or EF-S). Looks like since 2009, they have abandoned that practice (see 15-85mm). The 15-85mm lens is the only non-L lens released with USM since 2006 (17-55mm f/2.8 IS USM).

Additionally, the mounting dot is red, which is 100% indicative of EF mount.

Hmm... interesting... I wished for a new consumer prime in the 24-28mm range from Canon but I thought more about something in the lines of f/1.4-2.0, maybe even as an EF-S lens. Now we get these two lenses and I don't know what to think of them. f/2.8 is putting me off but image stabilization, FF and the fact that these lenses look pretty light and compact makes things interesting again, especially if the price is right and the lenses are sharp wide open.

Looks like no weather sealing, very disappointing :-[
In an area where annual rainfall is measured in meters this is more important than IS.
Canon wants you to buy the 24L, simple as that. ;)

In one of the other threads, it was mentioned that these images look like renderings rather than product images taken with a camera.

Given the various reflection details, etc, I think that explains why the images of the two lenses look so alike. It would be virtually impossible to recreate the same lighting, reflections, etc, on two objects that aren't identical,.
These look like normal product shots to me, in line with other product shots we've seen from Canon so far.

they announced the EF 24-70mm f/2.8L II USM not long ago, so not too long until this and the 28mm 2.8 is announced as well! also the above post proves this is actually on the way!

Holy crap, it's real!

And yes, it's EF. As I stated on the page for the new EF 28mm f/2.8 IS, the long drought of Canon non-L primes is finally coming to an end!

I want a 24mm prime for two reasons - shoot in low light situations, and panoramas using a tripod. I've considered buying the 24mm f/2.8, but the max aperture and IQ at corners made me decide against it, and wait for Samyang 24mm f/1.4, even though it's fully manual.

The new 24mm f/2.8 IS USM is as slow as the 24mm f/2.8, and from the MTF it appears to me the corners wouldn't be significantly better, so I'll pass. Had Canon made a 24mm f/2 USM with good corners, I would have bought it.

So, with all due respect to "up to 4 stops of shake correction", I'd rather keep on waiting for the Samyang f/1.4, and gain two stops aperture.

With this trend, the most I'll spend on the new primes would be to upgrade to 85mm f/1.8 IS USM & 50mm f/1.4 [IS would be nice] non-micro-USM.

Hopefully this is the start of a bunch of refreshes coming our way. In all honesty, these new 2.8 lenses make no sense to me especially looking at the rumored prices. Now if they were 1.8 or 2.0 then I'd be very interested but 2.8? for almost as much as a 2.8 zoom? ****** that shit!
