Sigma 50mm f/1.4 Art Gets Reviewed
« on: April 05, 2014, 03:47:32 PM »

SLRGear has completed their review of the highly anticipated Sigma 50mm f/1.4 Art series lens. We’re very happy to read that the lens just may live up to the hype created by Sigma themselves.


Says SLRGear

“The Sigma 50mm f/1.4 Art is the most exciting lens we’re likely to review this year. All competing lenses from Canon and Nikon fell short when compared to the resolving power of the 50mm Art. We haven’t (yet) tested the very best from Zeiss, but we are confident Sigma will trounce it in one key area: price. This difference is likely to be a yawning chasm. Our expectation for pricing on this lens is for something at least a bit less than Canon’s 50mm f/1.2 L, which goes for $1,700; despite a variety of rumors and no official price for the Sigma yet, we’re expecting it’ll be less than that.”


Pricing for the lens is expected to be announced on or around April 11, 2014.

A salesman at Henry's in Toronto said that the Sigma rep who was there a few days earlier said it would be around/less than 790.

The review reports a brilliant performance.
I am waiting for the critics to gather their talking points.

FINALLY a decent 50mm lens...

I will try this one...and I mean BUY it ...use it for 1/2 year...really try it out...
my 35 f1.4 is quite nice.. and the bokeh quality...
is about as good as the 35L(I sold)... sometimes a little busy..

but I am nitpicking on the 35 sigma...  a very nice lens

so,
if the bokeh on this 50mm is  reasonable...this lens will be hard to get....for a while...  IMO

---------------


now I want an 85mm f1.4 Arts lens...hurry hurry....

I am delighted... this 50mm is looking so good
I hear June availability...on the 50mm

That is awesome ... and if it is below $1000, that's even more awesome. With the way Sigma is delivering some great lenses, I wouldn't be surprised if they release a new DSLR or mirrorless, (within the next year or two), that that can take advantage of the resolving power of thise new ART lenses.

I certainly hope so, both for Sigma's sake and for my wallet. With all the stuff coming out this year I wouldn't mind if every lens they make immediately flies off the shelf until sometime next year. technically my 18-35f1.8 with a 7D2 will do everything I could want, but I'm a sucker for a good deal (and this lens is more than just a good deal).

Plus if you're shooting on crop this lens is going to be an utterly fantastic 80mm equivalent. Those chart readings with the 7D are phenomenal, at the same f/stop it's even better than the 18-35f1.8 at 35mm (though that lens does even better at the wide end).

I think a factor of 3 to a double gaussian optics is a good rule of thumb for a weight conversion into a retrofocus lens like the new sigma, 300 grams (for EF 1.4 50) x 2.5 is 900 grams. The sigma seems to use metal compared to the EF 1.4 50.

2 times the length + 1.2 times the diameter means 2 x 1.2 x 1.2 ~ 3

Sigma's famous statement: it wasn't looking to surpass Nikon and Canon, but rather the Zeiss Otus 55mm f/1.4 has a way to go judging by the graph in the review. I would have expected the FF graph to look like the 7D graph based on this bragging. The Otus' whole thing is sharp corners at f1.4. That's expensive to achieve.

I would have expected the FF graph to look like the 7D graph based on this bragging. The Otus' whole thing is sharp corners at f1.4. That's expensive to achieve.

You don't seem to know how to read the graph or what a typical graph is. This lens actually has LESS falloff in resolution between the center and corners than the Zeiss Otus, and 3 times less falloff in corner resolution than a typical competitor. On top of that it's as sharp in the corners wide as most 50mm lenses are stopped down in average resolution at f/2.8. For all intents and purposes it's tack sharp on full frame in the corners wide open. All lenses have some sharpness falloff in the corners, the Otus has significant drop, but for both lenses we are talking about being ridiculously sharp in the center and nearly ridiculously sharp in the corners. The Sigma is 2-5 times sharper than any other 50mm prime with autofocus in terms of average resolution, so the whole image is very clear.


You're also missing the point of their quote. The Sigma 50 A is not competing with canon or nikon it's competing with zeiss and makes Canon and nikon obsolete. That's the point of the quote, and that's what they accomplished.

We don't have a true side by side test yet.  Based on these results, I still expect the Otus to be sharper, corner to corner at f/1.4.  To get anything close to a side by side test, the Sigma 50 A is similar at f/1.4 to the Sigma 35 A in the SLRgear test.  I actually think the 50 A is a bit better. 

But here is a link to the Otus vs the Sigma 35 A both at f/1.4:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=917&Camera=453&Sample=0&FLI=0&API=0&LensComp=829&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0

The Otus is clearly sharper corner to corner when compared to the Sigma.

So, yes, the Sigma is blasting Canon and Nikon.  Excellent, IMO, but it likely is going to slide in slightly behind the Otus, which is nothing to sneeze at.  Considering AF, price point, etc....the Sigma will likely end up in more bags than the Otus.

EDIT---just checked Lenstip.com.  They have the Sigma 35 A and Otus 55 very similar at f/1.4. 

If the Otus is better than the Sigma 50 A, I doubt it is by much.  This review is a very good start for the Sigma 50 A.
