DXOMark Review: Sigma 20mm f/1.4 high score
DXOMark just posted their review and lab tests on the new Sigma 20mm f/1.4 Art, the world’s widest full frame f/1.4 lens.
When tested on the Canon 5DRS, it performed very well with a score of 40 points.

Read entire review at DXOMark.com

Very nice!

I'll sleep well tonight with my already excellent Nikon 20mm f/1.8G and the balance of cash in my pocket though.

Not when it comes to filters!

And then there's the difference in size and weight .

I paid much less for mine.

Sorry, the DXO scoring doesn't show a way better lens. I can see this being important to a pixel peeping forumer looking for their first 20mm or astrophotography though.

Looks like Nikon 20mm f1.8G on a D750 is equal to a Sigma 20mm f1.4 on a 5D3. I'll wait until they test these two lenses on a D8xx body before making any decisions. If it turns out the Nikon is pretty much equal, I'll just keep it because I like its light weight and compactness. If the Nikon scores 31 and the Sigma 40, I'll likely switch.

You can compare the 20/1.8G on the D800E, and the 20/1.4 A on the 5Ds R, but the results are even more distorted.

I will say though that DxO's sharpness field map for the 20/1.4 A at f/16 on the 5Ds R is particularly impressive!

what nobody is mentioning is that one is a 1.4 and one is a 1.8 lens. For astro thats ISO1600 or ISO3200. Big difference.

It's actually 2/3rds stop difference so about ISO 1600 versus about 2600.

Sigma never disappoints us. However, I have two copies of 20/2.8D and a Minolta 20/2.8...just wonder if I need another 20mm lens.

No you just need this one - the B&S board is that way...

The Adorama link is incorrect for the Canon mount. Should be http://www.adorama.com/SG2014CA.html

I think it has pretty high coma, so on FF I don't know how good it will be for astro.

Not conclusive yet. The only test out there is from Lenstip and their laser coma test is not the most reliable one. They are inexperience in wide-field astrophotography as well so I don't put much stock in their first star shot either.

I love the Sigma Art lenses but damn are they big and heavy. Plus no weather sealing. At their price points this has always been a bit of a bummer.
