Title: Rumor: Sigma 16-20 f/2 DG Art [CR1]
Post by: Canon Rumors on December 19, 2013, 09:12:16 AM
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.

Awesome if it is sharp across the frame!

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

It is almost a prime lens, but F2 looks great. ::) I would love a lente10-16mm (rectilinear) for APS-C. 8) C'mon Sigma. ;)

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??

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

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.

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

4mm of zoom?!

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

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

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?

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.

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.

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.

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.

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
It's targeting people who work in really low-light (street/night) where the difference between f/2 and f/2.8 is whether the milky way shows up, or whether they get motion blur. Not really sure the point of a zoom, I think an 18mm f/2 would be a nice split. And obviously when you don't need to shoot at f/2, it would sharpen up nicely at f/5.6-8

But a 16-24 f/2.8 lens appeals to a different user base than 16-20 f/2. I can get primes in the f/2.8 range that wide for much cheaper than a 16-24 f/2.8 would cost. I cant get primes/zooms wider than 20mm that go <f/2, and I can't get a good prime/zoom wider than 24mm that goes below f/2.8. There's definitely a market there for it.

This could also technically be targeted at videographers, as it becomes a different focal length with all the video crop factors, and the depth of field is important. But I'm guessing that's not the main market for it.

yep - as long as coma is minimal, astro use would be nice.

+1.

With that maximum aperture, you could forget that it's a zoom and buy it / use it just because it's a 16mm f/2. The moderate amount of zoom, provided it doesn't meaningfully reduce image quality compared with what a prime lens in that range could deliver, would be just a bonus. This seems to be the approach with Sigma's 18-35mm.

Whether or not there is any truth behind this rumour is another matter.

 Zoom lenses are constantly criticized for having non-useful focal lengths, offering a wide zoom range but only giving usable results within a specific part of that. Hopefully Sigma is working to address that issue, giving people top quality within a specific zoom range and not frustrating us with substandard results from unrealistic lens designs.

Man do I love Sigma. I wish they'd make this lens. :)

Or like CR said, a 16-24mm f/2
