Wow, it seems no time at all since the 50mm 1.4 DG DN, not something I had expected, or hoped for.. that would be a 135 DG DN.

I am sure it will be nice, but likely also close to 1kg, don't ever see myself using this.

Sony Alpha Rumors said it is 38g lighter and more compact than the Sony 50mm f/1.2 GM (Sigma weights 740g and the Sony 778g).

For reference of all L-Mount 50mm f1.4:

Sigma 670g  (70g lighter)

Leica 1065g (325g heavier)

Panasonic 955g (215g heavier)

 

Quite excited about this lens, the only thing left will be the price, which SAR also said it will be affordable than the Sony.

So it should be under $1999 USD (MSRP)

I own a Sigma 50mm/F1.4
As the new 50mm/F1.2 shall be about the same weight and size.
I am seriously considering to replace my 50mm/1.4 in favour of the 50mm/1.2

Price I expect about comparable, or just about $ 100.- or so more high above Sigma 35mm/1.2
(So about $ 1500 - 1600 USD ).

$1399 usd….very reasonable I think.

Here in the Netherlands / Europe - € 1499,-

As seen several tests in meanwhile at YouTube done by 60 megapixel Sony,
quality even better in centre than 50mm/f1.4 - but in corners just a bit lower. (Also to be seen by MTF graphs).
However the "real" tested focal length in comparison to other lenses, seems to be more short than 50mm.  It is more about 45mm focal length.
(To "compensate", the most close focus distance is 40cm instead of 45cm).

If that information is confirmed also with other sources, I shall keep my 50mm/f1.4
As I really don't want shorter.

Besides if it really is more short focal length, there is no benefit as for using f1.2 DOF / bokeh reasons
in comparison to a "real" 50mm f1.4 DOF / bokeh. As a more short focal length have more wide DOF.

The lens is very tempting. I have the 35mm F1.2 DG DN | Art 019 (1090 g). The IQ is stunning even at f/1.2 but it is as heavy as a rock block. The new 50mm lens weighs only 745g (1.6 lb) and 'Sigma says it made each piece of glass as thin as possible, reduced the weight of mechanical parts and used a new dual 'high-response linear actuator' (HLA) focusing system' (dpreview). Sounds to me as if a lot of metal has been replaced by lightweight plastic. This should have an effect on the lens quality and durability. Anyway, it is very tempting for all people with a noticeable problem of GAS (like me).

Airplane and aerospace parts are also built in polycarbonate instead of metal. This thing about quality (not even sure what you mean here) and durability was probably true 30 or 40 years ago, but definitely not in 2024.

Good point. If that were the case, I would take back everything I have written. However, I have not yet read anything from Sigma about these high-tech materials being used.
By quality I actually meant that mechanical plastic parts get play very quickly, become thermally deformed, break or whatever. Durable materials such as metal are somewhat better - but also heavier.

It’s on their website. Open one of the brochures. 
https://www.sigma-global.com/en/support/catalog/lenses/

I’m copy pasting from the 14mm, first on the list:

”The lens has a robust internal structure and uses lightweight materials such as polycarbonate TSC (Thermally Stable Composite) and magnesium in appropriate locations. The lens comes with the high build quality of the Art line, allowing the users to fully enjoy the unique performance of the lens in any environment.”

I don't think that the plastics used in modern high-end lenses are a huge issue. All of the structural parts are machined metal. It's not like kit zooms that have plastic lens mounts.

You may find that the outer barrel weathers a bit more over the years, compared to a metal barrel, but that's just the outer skin. You can buy a Leica lens for more money if it's a concern.

I guess there is no 50mm f/1.2 from Leica
