Ok, I read it to quick... Well, the Sigma does not have a release date yet... it just the annoucement, so we will have to wait. Anyway, the ART zooms of Sigma weren't so stellar as their primes. 24-70 art is not better than the Canon equivalent. But we will have to wait for reviews.

Well, the Canon 24-70 is incredibly sharp. It's not an easy lens to beat.

But the Sigma 24-35 is pretty incredible. And, looking at Lensrentals, the 24-105 is up there too, particularly when stopped down to f/5.6. It might just be the 24-70 that isn't up to scratch.

Now the 14-24mm f2.8 ART zoom has arrived...
https://www.dpreview.com/news/9856051689/sigma-announces-full-frame-14-24mm-f2-8-dg-hsm-art-lens

Let us see what Sigma can do about 11 years after the Nikkor made the 14-24mm.

11 years already... it is hard to overstress the extend of the lead they had taken with that lens.

I can hardly remember the person I was 11 years ago.  ;D

And they sat on it and didn't update it, while Canon surpassed their design and Sony went from not even having an interchangeable-lens camera to becoming a full-fledged competitor to Canon and Nikon.

Now, the Canon 11-24 and Sony 12-24 are king of the UWAs and the Nikon 14-24, which was so sharp on the 12MP sensors of the day, is now a sorry-looking lens with blurry corners (but still basically no coma) on the current 42-50MP sensors.

Stagnation never helped anyone. Just look at Canon - Canon's sensor weakness is largely responsible for Sony's existence as a camera (as opposed to a sensor) company. Nikon should have updated this lens five years ago.

5 years ago Nikon was trying to recover from one of the largest earthquakes ever and major floods in their main foreign manufacturing site in Thailand... It is a miracle they managed to remain this good in these circumstances.

So, it looks like it is a 105 mm f1.4 and a 70 mm macro, both Art lenses for Sony Full Frame mirrorless... interesting choices, since they fill gaps...

Ok, reading again... looks like it is the same version of lens they are going to release for Nikon and Canon but just with Sony FE mount...

Yikes that 105mm lens looks gigantic, even for Sigma's standards. And I thought the 85 art is as bad as it gets.

Hey, be cool, I was just kidding and trying to think of something to do with myself, so I decided to watch two Sopranos episodes in a row.

I discovered a funny thing about myself: I hate to see scenes where young boys are trying to have it off with young girls... I must be thinking of my own kids when they were in their teens. Morality ain't no bad thing, especially for somebody else.

I get the feeling that massive thing at the front is lens hood, rather than the lens itself. Although why a 105mm lens would need a hood so much wider than the front element is another question entirely - it's not like it's a UWA.

I wonder if the Sony version will have a button on the lens to assign to eye AF, as with the Sony and Sony/Zeiss lenses. Also, will it take teleconverters? For portraits (and this is obviously a portrait lens) I always found 135mm f/2, 200mm f/2 or even 200mm f/2.8 much more useful than shorter lenses with wider apertures - you end up with the same amount of background blur (the longer focal length compensating for the smaller aperture) while the smaller aperture means you get more than one eye in focus (with the corresponding eyelashes already blurry, and the tip of the nose way out of focus) with a head or head-and-shoulders shot.

We will have to wait and see, but... the Nikon 105 f/1.4 is almost 1 kg and takes 82mm filters. Seems like the Sigma for DSLR will be even bigger, and for FE, if they do a simple adaptation, they will have to add a spacing for the converter...

Long time ago since I saw one episode of The Sopranos... so I don't remember those teen love scenes...  I will agree with you, in a series like Sopranos, losing time with young boys trying to have it off with girls... having more interesting scenes to see...

Now Sigma is going to release a new extreme lens , the 105mm f/1.4  Art,  half a year after Nikon did.

I am sure the lens will be very very good optically, but it weight 1645 grams... ! filter size 105mm
weighs more than a 70-200 f/2.8 zoom...( and has no VR)
It will make the 135mm f/1.8 Art lens look small and lightweight...
one thing i really like : it has a arca swiss tripod mount- at last ! ... kudos to Sigma.

The Nikon 105mm f1.4 was released during the summer of 2016.

I got mine in Sept 2016. ;)

I am sure the Sigma is excellent, but that level of bulk is getting unmanageable in my view.

Now, the strength of the Nikon is the combination of very high tech excellence AND look.

Cheers,
Bernard
