Wow! When Photo Rumors plays he "This is the_______" card with the title, that's a like a CR3 for them. Talk about coming out of nowhere.

Astro folks rejoice?

"Very low distortion and minimized coma" sounds good to me

 

[BeenThere]

If true, good news indeed. The Sigma 24mm Art had coma issues when aperature was greater than f/2.8. Going wider to 20mm makes it even harder to reduce coma. We will have to wait and see how well this rumored lens actually performs for astro.

Ok....wow. Didn't we JUST get a 24mm from them last Tuesday? : ???

I dunno, guys. I'm not big into using wides for my work since most of what I prefer is portraiture. Is there really a market for 20 AND a 24 so close together in release? Asking for opinions and thoughts. I like what Sigma is doing though.

Who's selling their 16-35mm f4 Canon for this... decisions....

If 24mm is your environmental portraiture lens, surely they'll aim the 20mm at the astro crowd, right?

Also, if they think 20mm -- by any measure, a lower priority FL -- is worthy of Art status, perhaps Sigma's ambitions are bigger than we thought. I had originally thought we'd see the staples of 24/35/50/85 and that might be it. But going after a 20mm variant makes me wonder if a 100mm or 135mm is also up their sleeves.

20?! I love Sigma's new ART lenses, but ... 20?!

I wonder what they could do at 200 or 135mm? Think they could pull off a 1.8 on either? That would be epic, and I'd throw my $ down immediately.

 

[nightscape123]

a 20 f/1.4 would be a game changer for astro work. If it has low coma and decent vignetting control then this would be the must have lens of the year for astro work.

I'd buy this up in a second if the coma isn't too bad.

 

[Viggo]

Wonder how they will go about the 135. The L isn't very expensive and epic IQ. I don't think I would buy a new Sigma 135 with OS over a mint used 135 L. Af on that thing is crucial.

Well, Sigma A 24 mm f/1.4 DG HSM coma sucks!

So I wouldn't get my hopes high until a review...

Of course I will consider it, if coma is really low...

 

[CarlMillerPhoto]

Astro photog's wet dream. Sigma is killing it and they're not letting up.

Even if the 135mm Art they make is f/2, it will still blow the doors off of the now 19 year old 135L, so I'd still welcome it at f/2. (f/1.8 would be gravy, though.)

[NancyP]

Gosh. And my dream was that my beloved Zeiss 21mm f/2.8 would wake up and become f/2.0 for astro work... The Zeiss is wonderful for astro at f/2.8, but two times, or four times, the photons would be unbelievable, if coma is small.

 

[davidcl0nel]

Oh oh, this might be expensive for me.... ;-)

A game changer.... but where is the 85A?

 

[ahsanford]

Also, though I'm sure it won't perform like the 28 Otus, I wonder if that lens's widely announced arrival prompted Sigma to sneak in with this 20mm leak to give the pre-ordering world something else to think about.

(I recognize those lenses are likely apples and oranges to one another, but an f/1.4 wide lens is an f/1.4 wide lens -- the Sigma might be able to do 80% of what the 28 Otus could do for 1/4 the price.)

As someone pointed out in the Photo Rumors comments, it looks like a fixed hood and there are no markings for a filter thread size. So in all likelihood this is a bulbous front element that won't be able to take a standard front filter

I guess there a trade offs. Haven't seen an f1.4 lens this wide before, I don't think.

That is the shocker. Surely, the 85 Art would sell 5x what this odd FL will sell. There simply are more portrait folks out there than astro folks.

Good catch! That relatively small Digicame photo doesn't show the hood-to-lens lineup dots like the other Art lenses. This very well may be a fixed hood, which would royally p--- off landscapers.

Seems a shame if so. Canon and Nikon can pull off 16-something zooms with front filter rings -- why couldn't Sigma?

[ahsanford]

On the other thread, someone pointed out that the hood looks integral on this lens. No hood-to-lens lineup dots are in that picture.

That's an ouch for landscapers.
