Here are SIGMA’s three new full-frame mirrorless camera lenses

KT · Jul 10, 2019

Is it 12-24 or 14-24, the leaked pictures clearly says 14-24???

I think DN is for crop sensor bodies and not FF.

DN is for mirrorless cameras with short flange focal distance in general.
The Addtion of DC (for crop) or DG (for FF) is the important part.

I wonder if they are built from-the-ground-up for the short flange distance, or are just redesigned mounts for existing full-frame lenses. The 12-24 f/2.8 comes to mind.

If SIGMA 35mm f/1.2 will be released for Canon RF in the future with optimization (different optical formula) for RF Mount, it will have significant space, or may be IQ, to improve.

A 35 1.2 on a Canon RP would be very nice indeed!

I'm definitely not thrilled about the aperture rings.

Why? I'm not being snarky; just curious.

Does the Leica mount still have a mechanical linkage: It looks like there is a flippy lever on the back of the lenses which would answer why the aperture rings for the Leica at least. Otherwise no real reason for them for canon at least as that is controlled by the camera or multifunction control ring.
Who knows.

I think it's a good thing. Coming from someone whose been using the Control Ring (CR) adaptor, I would be bummed to loose the ability to control part of the Exposure Triangle on the lens barrel. I currently have the CR set to control the ISO, but I could easily get used to mapping it to the rear thumb dial given that the Sigma lenses have dedicated aperture rings (small compromise). This makes the Sigma lens even more attractive to me!

Another observation: I wonder if all the Art series lenses will have the AFL button - just below the AF switch.

So excited for The RF lens!! Will it have IS ?

Aperture rings almost certainly mean they want to target film makers more than stills photographers.
Look at the geared ridges on the focus and aperture rings. I'm honestly surprised there's no t rating on them.

Sony Alpha Rumors is reporting a $600 price for the 45mm 2.8... And people call Canon lenses expensive! That's ridiculous for an f2.8 normal lens.

It's not exactly a $600 price, it's a ¥64,800 Japanese price, with the 8% Japanese VAT included, the dollar conversion of which gives $600.

Bennymiata · Jul 10, 2019

I wonder how many of the L mount they will sell.
Personally, I can't see too many Leica owners buying Sigma and the Panasonic FF won't sell in huge quantities either.

OK, so say the US MSRP is $550 or even less.

The exact price isn't the issue. If Canon took the EF 40mm f2.8 STM (currently available for $179), changed it to RF mount, added a control ring (in lieu of Sigma's aperture ring) and sold it for $499 people would lose their shit. Presumably Sigma's optical formula is better, but it's still a physically small lens with relatively small aperture.

The RF 35mm f1.8 IS Macro is only $499, and if history is any indication we should eventually see an RF 50mm 1.8 for a lot cheaper. I don't see how Sigma's lens fits into reality (possibly unless it's a Cine lens as I saw one person speculate, but I haven't heard any real evidence for that)

Ale_F · Jul 11, 2019

Are they a real short-flange "new" design or a simple FF SLR lens + a ring?

From all we know about the recent Sigma lenses, the build quality will be quite a bit higher than the RF 35mm. And from the pictures you can tell, that there is at least a rubber gasket around the lens mount.
Then there is the fact, that these lenses are announced for the E- and L-mount today. The RF version will most likely come next year. So you're better off just buying the Canon lens, if you need it right now.
