SIGMA announces three DC DN prime lenses for the EF-M mount

About time too!

Seeing as the M series are very good sellers, 3rd party lens manufacturers have been missing out.

i suddenly have a dumb smile on my face )
i've been waiting for this announcement since the first DN lenses

Certainly great news! Though not for Canon, just as they finally released a fast standard prime for the EF-M, Sigma comes and undercuts them with an alternative with (likely) equal IQ but almost half the price!

the made an announcment for a smal FF camera as well

Good news. Not because I will buy any of these lenses but it will give Canon some pressure to release more lenses, especially Sigma's juicy 56mm 1.4

Perhaps Sigma knows more than we here do about the long term future of the M mount. Good news for M owners.

Awesome! I'll definitely be getting the 56, and the 16 is super interesting as well.

Not only RF mount. Looks like they disregard Z mount as well.

The 16mm f/1.4 would be great for vlogging on the M50, and right now the Sony E & M4/3 mount versions are on sale for $399, very sweet deal.

I wonder how many M-system Users have used the Canon EF-M mount adapter to adapt Sigma or Tamron (or others') lenses for use on their M-systems? And more importantly, what that experience is like.

For example: I hear and read very good things about Sigma's MC-11 Canon EF to Sony adapter and how Sigma and Canon lenses adapt very well for use on the Sony's (perhaps I should caveat this with: at least on the A7 III)...

I find it interesting that Sigma's last, I think, 4 lens releases have been able to be "AFMA'd" in Canon cameras with that capability. So all of the Sigma specific lens 'quirk' data can be appended to RAW files and/or adjusted for in camera. Either Sigma Engineers have solved the Canon Enigma or they have made a quiet (non-publicized) agreement with Canon. And perhaps they have a deeper agreement with them: we'll make Prime lenses for your M mount (so you don't have to invest in that) but it will help to continue selling your M mount cameras...

I don't use or plan to use the EF-m system, but more competition is always good! So is having more lens choices and more viable systems

wonder which EF-M lens IDs Sigma will spoof for these lenses to make reverse-engineered AF and lens-mount communications plus dependent functionality on EOS M cameras sort of work.

But I do hope it helps to finally bring on Canon EF-M prime lenses longer than 32mm and the price for EF-M 32/1.4 down.

As an owner of the M5, I'd be looking at the weight of the new Sigma EF-M lenses. I bought my M5 to shed weight hiking. I use it sometimes for video or portraits, but my 5DS and EOS R covers most of the other. But if the new Sigma lenses are hunky like the ART line, even in part, it would defeat the design of the M series. Regardless, this is one extra small sign for a long shelf life of the M series.

Normally I roll my eyes at the "rawr mirrorless was supposed to be small!" comments, but in this case I think it's correct. Everything in the M series so far has been about portability and being lightweight, and the ART line doesn't really fit that.

I wonder if this has something to do with the rumor of the EF/RF crop cameras being offset to the EF-M line.

Something like the M5 and certainly an M5ii are robust and versatile enough to fit many use cases not just limited to "hiking and travel" ... I see the native ef-M lenses, particularly the 18-150 and 55-200 as ideal for that type of use case. M6 and the 55-200 is a dream for travel and I love it. But, it doesn't exactly break my brain to adapt L glass or Art glass for portraits, etc.

If I look at the 30mm DC Art lens: The EF-M 32mm is by far the better lens (see the-digital-pictures.com) and I have my doubts that two additional lenses (9 lenses in 7 groups for the EF-M compatible 30mm Sigma) will do the magic trick and lift it to the IQ of the EF-M 32 with 14 lenses in 8 groups. The EF-M 32 is by far the best lens I have ever used just at f/1.4 .
EDIT: And the max. reprod ratio of 1:4 is - for me - a very strong argument for the Canon lens because it is half way to macro while the Sigma will have presumably the same 1:7 like the Sony version.

But you are right that for lots of us some minor penalty in IQ at half the price is fine: As someone who need wide angle very seldom the 16mm will be a good companion e.g. on my old EOS M (in a triple setup with M50 + EF-M 32, M50 + EF 4 70-200 in a small photo backpack - never change lenses anymore).

EDIT: And if it motivates Canon to do a EF-M 1.4 60 mm and an EF-M 2.0 85 IS both with 1:4 max. reprod. ratio - would help to increase choices!

sigma 56mm for sony weighs 280g, 10g less than the canon 50mm 1.4 alone and the same as the 1.8 stm together with the canon adapter
