<strong>Sigma 16-20 f/2 DG Art for full frame


</strong>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 <a href="http://www.canonrumors.com/2013/07/sigma-24-70-f2-os-hsm-coming-cr1/" target="_blank">heard about Sigma working on a 24-70 f/2 DG Art lens for full frame cameras</a>, but nothing else has been mentioned about it in a while.</p>
<p><strong>CR’s Take</strong>

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).</p>

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. 8) 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

 

[Zv]

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.

 

[fox40phil]

would be awesome!!

 

[Etienne]

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!

 

[rs]

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.

 

[bereninga]

This would be an interesting astrophotography and landscape option if the price is right for the quality! I'm glad it's f/2, but I worry about its size.

 

[Pag]

This could be a great replacement for my Tokina 11-16mm f/2.8 now that I'm on full frame.

Yeah, it might be even less, depending on how marketing "rounds" the numbers. For all we know, it could be a 17-19, lol.

 

[Viggo]

I was about mention the Tokina, it only has 5mm of zoom so 4mm isn't completely insane. The f2 is though, and in a great way ;D

Its all about the zoom ratio, not the zoom difference in mm. A 200-400 lens spans a 200mm zoom range, yet its only a 2x zoom. Compare that to a 24-105; 81mm zoom range, yet it's 4.4x.

The Tokina 11-16 has a 1.45x zoom range, compared to a more conventional 10-22 or 16-35 at 2.2x. This rumoured Sigma has about half the Tokina's zoom range at 1.25x, which can't provide a dramatic framing difference however you look at it.
