i can give you a hint:

Sigma Art glass is typically priced at around a $1.00 per each gramm of the lens weight. so around $1100 -$1150 is a good price guestimate.

I'd take that  ;)
I honestly expect it to come at a higher price. It looks similar to the 12-24mm, both physically and in terms of optical design (same number of elements, same aspherical big-ass front element), so I expect it to get a similar price tag, around $1600. Of course I hope I'm wrong.

Am buying. :)

I probably will, too.  I've had the Rokinon/Samyang 14mm 2.4 on order since 12/30/2016, and now it is not expected until late March.  I've about had it with Rokinon/Samyang.  And this Sigma is a full stop faster!

I doubt that sigma will price this lens at the level of 12-24 lens. You are correct lens are similarly designed and constructed. Still prime vs zoom. Around $1250-1300. Ok.  possible. Interestingly enough, street price for 12-24 Art in Australia is only around US$1250.

Can't wait!!!!! 8)

My buy decision will be largely based on how much it distorts.

I'm greedy - I want reasonably low distortion, sharp edges wide open, low coma, low lateral and longitudinal chromatic aberrations wide open, reasonably low vignette and spherical aberration and good flare control.  I can live with heavy weight and don't care much about AF.

Tron,

at least vignetting is not too bad at 2EV in extreme FF corners wide open. Good starting point though :)

beautiful bokeh effect my @_ _

Not a single word about coma...
Hello Alex,

if this Sigma has low coma I will go running for it  :) against my beliefs that I want to shoot only with Canon for future compatibility reasons - OK I will get the dock too   :)

Where did you see the 2 stop vignetting at the corners for the new 14 1.8 Sigma? This is a very good number indeed!

Coma? Here's hoping that "Lenstip" Polish review site gets its hands on a copy soon. It's the only site that routinely tests for coma (with a laser pointer as image).

I'm with you; LensTip provides the most thorough and objective reviews I have found.  But other sites do provide astro shots for coma evaluation.

This lens is now on B&H's site.  I have placed one on 'notify when available'.

"Distinctive bokeh effect" even at 14mm. I'd like to see that.

According to my calculator: 3ft from the subject at f/1.8 / 14mm... focus kicks in at 2.4ft runs 1.62ft deep to 4.02ft and then back out of focus. Hyperfocal distance at these parameters is 11.91ft. None of this, of course, means the bokeh is any good.

6 ft. from the subject gives a depth of field 8.11 ft deep.

Some of you that are gonna buy right away ( before testing or reviews) are brave souls.

Then again, surely there will be some independent testing before it hits the store shelves.

I'll never be that brave.

My wish: Good autofocus, edge sharpness, less than 3 stop vignetting.

My use will be low light crowd shots.

Pro: Distortion control seems solid!

Con: 2+ stops of vignetting in the corners wide open.

All in all, looks like a pretty awesome tool!.  Sigma tech data here.

Thanks for the link. Actually 2 stop vignetting at 1.8 is good news not bad news.

I have yet to see such an uwa lens with less vignetting than that. On the other hand there are many with 3.5 to 4.5 stops of vignetting...

Now back to coma...   8) 8) 8)

EDIT: Since I shoot astro during summer I can have a little patience  :)
