New Sigma 50!!
Sigma announced a new 50mm F1.4 DG HSM | Art lens.

The new Sigma 50mm F1.4 DG HSM Art has been reengineered and redesigned to set a new standard of performance in the Art line.
It has been updated to include SLD glass and optimized for rich peripheral brightness with improved large aperture performance by positioning wide elements into the front groups.
Other updates include an optimized autofocus algorithm for smoother focusing and a floating focusing system to reduce lens movement while focusing. Under the Global Vision line, it features a new matte finish, improved AF on/off switch and guarantees every lens is tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system before being shipped.
Now with 13 elements in 8 groups compared to the previous 8 elements in 6 groups, it also has improved close focusing at 15.7 inches and a maximum magnification ratio of 1:5.6.

I am just beyond thrilled. With the current pricing scheme I am really hoping it will come in sub $800

Just read the blurb on DPR . Apparently its a complete redesign rather than an update of the existing 50 .

Also , not that it should be an issue but I see it only stops down to f16

Nice indeed considering what Sigma has been producing lately.

The lens is pretty big for a 50mm f1.4 prime. It's virtually identical in both size and weight to a 17-40L.

If it's sharp with reliable AF at f/1.4...my 50 1.2L might get nervous.

It's about 50% longer than either the preceding Sigma lens (or the 50L), but it's also a little lighter, and with the same 77mm filter thread. It shouldn't be much of a change if the balance isn't out of whack, and the ergonomics look to be a little better with the larger focus ring that's positioned further away from the lens mount.

I'm looking for better contrast at f/1.4 and far better control of LoCA; basically something that can challenge Nikon's new 58/1.4G.

Hopefully it can focus in lower light than the 35 f1.4.

Bravo Sigma!

The current Art offerings are simply awesome. This will have to challenge 50mm offerings especially from Nikon and Canon.

Sheesh, 100mm long and 77mm filter. That's one big honkin' 50 1.4! I'm guessing the largest design yet. Sigma's Art series for M43 are also usually large for primes, 2 or 3 times larger than Oly and Lumix. I wonder if it's easier/cheaper to design quality optics with more airspace between the elements?

Over the holidays I picked up the Canon 35mm f/2 IS. I am totally happy with it. I've been hoping that Canon will introduce the next two lenses in their non-L prime upgrade sequence: 50mm f/1.4 IS and 85mm f/1.8 IS. Based on past experience, I think I would rather have the Canon 50mm, especially if it has IS.

But, this Sigma 50mm looks nice. I might try it on my 5DIII with the AF dock.

the 35 was supposed to be geeat, so many people ended up taking them back due to incosistant focus. I had the same bad experiance with the sigma 85 and will probably be skipping this lens.

I recently acquired the Sigma 35mm and very much look forward to this new Sigma 50mm. The build quality and performance of these new ART lenses exceeds most of my current Canon lenses.

Now THIS I may even consider.

Although if they come out with a 135 1.4 I would DEF be picking that up IF it's anything like the 35 1.4 optics.

Canon Pants: Do you mean the 35 Canon or the 35 Sigma? Cause I haven't heard of any instances of people not LOVING the Sigma version. From what I read and see everyone who has one says it's the best IQ in a lens that they have.
