Patent: EF-M 15-50mm f/3.5-5.6 IS STM

[TeT]

Quite similar to the existing EF-M 15-45mm f/3.5-6.3 IS STM lens...not sure we'll see this one produced.

...

I suspect the lenses Canon has lined up this year are (from rumors, and my opinion):

EF-M 35mm f/1.8 STM
EF-M 55-300 DO IS STM (maybe USM, ie nano-USM)
EF-M 9-18 IS STM

The EF-M 28mm f/3.5 IS STM already counts against 1 of the 4 rumored to be coming, so the other 3 fit nicely. Too bad, I'd like a 15-85 or f/2.8 constant zoom this year. My guess is next year perhaps, or never.

Can I get an M4 with that, I could live with this lineup with the addition of either the 15 - 45 or the 18 -55

I'm working on the M5 so I can install it in the Enterprise and show Starfleet that humans are not needed to pilot starships.

I sure would like a EF-M 15mm f/2 prime

+2 as long as its pancake,
+1 any 15mm to 18mm

Mount the EF-M 22mm f/2. Take three steps back. Done.

Seriously, though...15-18mm puts it into retrofocal design territory, it won't be a pancake, it will be bigger and heavier, and more expensive. I doubt such a lens is high on Canon's list of priorities.

Granted it wouldn't be a pancake design, but it could still be pretty compact given the flange focal distance of the EF-M mount is only 18mm. The Fuji 16mm f/1.4 isn't a huge lens and an f/2 design would be even smaller.

I agree that this lens is probably not high on Canon's to-do list, but I'd argue that it probably should be, as wide angle lenses are where you can get the greatest size benefits of mirrorless (for the reasons mentioned above). Longer focal lengths can be covered using adapted EF mount lenses, but where are the options for fast wide primes?

This is probably due to Canon's analysis that crop sensor users don't buy primes, hence the dearth of EF-S primes. I don't see how they can make such a judgement considering they have only ever sold two non full format prime lenses. It's hard to sell a product you don't make!

Hmm... The Ricoh GR/GRII and Fujifilm X70 both have APS-C sensors and pancake-sized 18mm lenses. Granted they're fixed-lens cameras, but it looks like it can be done.

Fair point. 18mm could likely be done, but I doubt 15mm.

I think it's still possible for slightly retro-focal designs to be made in a pancake form factor. In this patent, embodiments 3 and 4 have focal lengths less than the back focus distance, yet still have very short overall length.

Thoughts?

Could be, although they did choose to produce the 40mm one.

In any case, there's already a UWA zoom, with an even wider one patented. Given the target audience and the lack of an EF-S UWA prime, I don't think we'll see one in the M mount any time soon, pancake or not.

I hope you spend some quality time with the 22 before you flip it. It is by far the best M prime available.

I see what you did there...

Hang on -- technically there are two now. :

a·vail·a·ble əˈvāləb(ə)l/

I want an EF-M prime other than the 22/2, and I want to use it this week. How can I obtain one?

Well, I contend ahansford's statement was technically correct! Brad-man did not expressly specify in what sense he meant "available", and clearly he and ahansford were referring to in the sense of available to order, which both the 22 and the 28 are (albeit it is a pre-order for the 28). It was only neuro who introduced the requirement of being available to shoot with. You shouldn't have run up the white flag so quickly ahansford

In any event, though, I think neuro was just talking about flipping pancakes!!

Still waiting for that elusive EF-M 35mm f/1.8 STM we've heard so much about.

@ tiggy: I hope you spend some quality time with the 22 before you flip it. It is by far the best M prime available.

Ditto, it'd play with the 22, especially considering your interest in the 35 as it's so very similar in usage, except, you have to get closer with it obviously.

The 22mm is a great little lens on the M. Of course there is not much competition there. Biggest weakness can be it's somewhat slow focus speed.

As for the original topic at hand, I agree with others, nothing to see here. Probably will not come to fruition, and even if it did, just another rather boring, slow normal zoom.

There are actually a ton of primes available for EF-M -- just not with AF.

Technically, that's depends on how you define an 'M prime'. But you're right, lots of 3rd party options.

While RoBoSam certainly have been more prolific than Canon in producing M mount lenses, I'm not sure if eight or so lenses constitutes "a ton" I was seriously considering the Rokinon 12mm f/2, but I fear I would eventually loose interest in a fully manual lens. I guess I'm just too lazy. Hopefully the new prime will enlighten an army of macro-enthusiasts to go out and purchase enough Ms so that Sigma will show the mount a little love. We can but hope.
