The 24mm is 2.8, any lens bellow this focal length is more expensive to make, and even more expensive to make it fast. 99% sure will be a 2.8 lens.

ashmadux said:It should be a 22/f2 as an ef-s version of the sweet M lens, or anything below 15mm.
15 @ 2.8 mm on crop is, well 'crap' - not interesting in the least. 2.8 on crop isn't spectacular either, so go lower or go home.
12mm? now your talking

Canon Rumors said:ahsanford said:Also, to CR guy -- an isolated lens announcement for crop seems oddly timed. Any chance this might be announced alongside something else that it might go with? The Rebels just got a refresh and an 80D or 7D2 replacement isn't the right timing, so I can't think of anything 'crop-appropriate' off hand... unless it's an 80Da or something, and that seems a reach.

There is no other DSLR coming in 2017 other than the 6D2 and SL2, we don't have an announcement date on either of those.
Canon in the past has done a camera announcement and then relatively quickly after, a lens announcement. This lens will be good for buyers of the 77D and T7i.
I'll try to get the SL2 announcement date asap.

a 22mm f/2 then?

No, 22mm 1.2.

Canon 35mm IS f/2.
I recall Scott Kelby's conclusion about the essence of the 7D2: making it possible for parents to take really good sports photos without having to pay pro gear price.traveller said:Isn't it a strange new world when Canon are making the budget lenses and leaving the high end to Sigma?
KristinnK said:Canon is really making it difficult to want to use their crop-frame cameras. There is a good telephoto lens (55-250mm STM) and an OK standard zoom lens (17-55mm f2.8 ). Even that one isn't really anything special. It's a 27-88mm f4.5 full-frame equivalent lens. Meanwhile the 24-105mm f4 full-frame lens is considered lackluster. Only other crop frame lenses are small aperture ultrawides (which are bad for night-sky photography), a 24mm f2.8 prime and a 60mm f2.8 macro lens (100mm f4.5 full-fram equiv.). You're forced to use at least 1 to 3 full-frame lenses, which means paying for a 1.6^2=2.56 times larger image circle. At that point it's almost worth it to buy a full-frame camera to be able to use the whole of these lenses, which means also replacing the couple of good crop lenses with full-frame lenses. And that's exactly what Canon wants...
KristinnK said:But this better be a real UWA, i.e. 10mm (16mm full-fram equiv.) or wider, at least f2.8 (f4.5 full-frame equiv.), and preferably f1.8 (f2.9 full-frame equiv.).

f/2.8 on crop is also f/2.8 on FF. It just "appears" to look like a f/4.5 in terms of depth of field (because you have to go further away with crop to get the same framing as with a FF camera), but in reality the depth of field between crop and FF sensor is the same (DOF depends on something else, see below). And also in terms of light-gathering ability; f/2.8 on crop lets in the exact amount of light as a f/2.8 lens for FF. It just "appears" to be better because FF cameras usually have a better signal to noise ratio than crop cameras.
The DOF. is only dependent on the distance between your sensor and the subject (not the sensor size) - and of course the chosen aperture. Just to clarify.
