Rumor: Sigma 16-20 f/2 DG Art [CR1]

Sigma 16-20 f/2 DG Art for full frame
A rumor has surfaced talking about the possibility of a  Sigma 16-20 f/2 DG Art series lens for full frame cameras. We had previously heard about Sigma working on a 24-70 f/2 DG Art lens for full frame cameras, but nothing else has been mentioned about it in a while.

CR’s Take Possibility of this? I’m not sure, that’s a very short zoom range. I think something like 16-24 would be better and put real pressure on both Canon and Nikon (the Nikon 14-24 is terrific and expensive).

16-20 f/*2*??

Want.

[Ricku]

Awesome if it is sharp across the frame!

Canon still doesn't have any tack sharp UWA-zoom lenses. 

[ajfotofilmagem]

It is almost a prime lens, but F2 looks great. I would love a lente10-16mm (rectilinear) for APS-C. C'mon Sigma.

[emag]

That's a narrow range.  f/2?  Really?  On an UWA?  Why?  I'd be happy with a 16-24/2.8.   Just my $.02

4mm of zoom? Why bother? I guess there is quite a difference between 16mm and 20mm on FF but why not just pick one focal length and make it awesome. Like 16mm or 17mm f/2.8 would be perfect.

Would this lens be the worlds shortest zoom if it was made??

[facedodge]

f/2 would be good for star photogs. You can get some bokeh out of an UWA. This is 14mm at 2.8

[alexanderferdinand]

I love ideas like that.
4mm difference seems not to be very much, but makes a difference in wide angle.
At f2.
Worth a look.

would be awesome!!

Interesting, but I'd rather have a small light 16-24 2.8.
But I'd take a 24 f/2.0

[Ellen Schmidtee]

4mm of zoom?!

Then again, it's at least a stop faster than Canon's prime at those focal lengths.

[tat3406]

Make it prime 16mmF2 or 20mm F2, I would rather have more compact size than this small zoom range.

[The Bad Duck]

Oh please make it 14-20 /2.8 instead!

Really?

I put this one down as either misinterpreted info, or wishful thinking. All previous fast zooms have not outdone primes in terms of max aperture in their equivalent range. Take 24-70/2.8's or 70-200/2.8's - plenty of faster primes covering those ranges.

The 18-35/1.8 from Sigma is a crop camera lens, covering an equivalent of 29-56/2.9 on full frame - direct equivalents are the FF 24/1.4 and 35/1.4 lenses, which outdo it. Nothing fast exists around the 18mm mark, so it is very impressive for crop. But when compared to a FF system, just like a 24-70/2.8, its nothing special compared to FF/fast primes.

How is it possible to make a lens a whole stop faster than any prime in its range, and also make it a zoom? I know its a limited range zoom, but really?

[gfoulk]

Want. For one reason only: 16mm f/2 would make a fantastic night sky/landscape lens (provided, of course, that it's sharp wide open.)

The zoom range is pretty silly, as this would be just as awesome as a 16mm prime.
