Now Sigma's just toying with the folks who were pining for an 85mm f/1.4 Art, who thought they'd be next in line for Art prime goodness.

Well yes please! If this turns out to be true, it will be an instant buy. Awesome for astro!

 

[mrzero]

That looks pretty awesome. I might just go for that bad boy instead of the 16-35/4. Different beasts, of course, but a tough choice for a single spot in the bag.

'•Designed to minimise coma aberration'. Yes, please!

'•Designed to minimise coma aberration'. Yes, please!

+1. If IQ is up to snuff, this may be the first Sigma I buy.

One might imagine that in this unique case, the resolution testing we usually look for first becomes the second most important test for prospective buyers.

Correct me if I'm wrong, but night sky coma is the real world test that makes or breaks this lens commercially, right?

I sense a pre-order in my future ...
I have a Northern Lights trip scheduled for February, hopefully I can get my hands on this lens by then.

Right. Coma, or lack there of, is THE key spec for astro. 20mm f/1.4 certainly gets the juices flowing if indeed coma is well controlled.

MMM. How to justify, given that I have a beloved Zeiss 21mm f/2.8? 4x the photons would be wonderful, if coma is tiny.

I'm not an astro person, but doesn't 20mm + f/1.4 blow the doors off of other common choices for astro?

I've read charts like these which consider light gathering vs. FL max shutter and such, and wouldn't a 20 f/1.4 -- if coma was acceptable -- net some terrific shots?

Damn...just when I thought that I had everything...I had the Canon 16-35mm f/2.8L II...and a Zeiss 21mm f/2.8.
So I sold off my Canon 16-35mm f/2.8L II to buy the new Canon 16-35mm f/4L as is was such a sharper lens...and it is sharp! It was so sharp...that I stopped needing my Zeiss and sold it, as it was redundant at that point (which I found hard to believe..yes..did I mention that the new Canon Zoom is SHARP!? LOL!).... ...anyway..hmm...20-21mm is one of my favorite sweet spots for shooting....and I can have f/1.4 AND autofocus! hmmmm.....I already have the 35mm and 50mm Arts..and I think that they are stellar if you get a good copy and calibrate them correctly on the dock. Just well-priced stellar lenses..so...um...Sigma...come take my money!!!!!!!!!!! LOL!

Count me in! Might as well start selling my Samyang 14mm.

 

[abbaen]

How much longer must I wait for an 85 Art

Although this is the first 20mm 1.4 ever I believe? Great things from Sigma again.

First ever for an FF SLR, I believe. But I believe Leica M had a FF 21mm f/1.4 for 5-6 years now.

Yep it would score around 3200 on that scale, significantly better than anything else on there. Though it really comes down to coma and vignetting. If there is 5 stops of vignetting then it isn't really f/1.4 for 50% of the sky.

Yeah I agree. A 20mm? Common guys... get that 85 out.

 

[ashmadux]

Where's the kool aid man when you need him, because..

OOOOOOOHHHHH YEEEEAAHHHHHHHHHHHHH

8) 8)

This is a very interesting focal length and could be a really killer lens. Nice to see Sigma thinking outside the box again. I look forward to giving this dude a test!

 

[vscd]

This small familybased company surprises ones again. A 20mm f1.4... yay. Could be the first time that I buy a Sigma (at least a lens, I own the fabulous DP3M). The must be a new engineer-samurai inside the team, with intense karma

Count me in! Might as well start selling my Samyang 14mm.

I wouldn't sell my Samyang anytime... and the Samyang is nearly perfect, Coma-wise. And the 14mm Look is totally different from 20mm.
