Just a day after Sigma announced its 24mm f/1.4 Art lens, it has now also announced both pricing and availability of the Sigma 24mm f/1.4 Art lens. I honestly expected over $1K price for this quality of the lens, so I was a bit shocked to see that the lens will be sold at $849, which is tremendous value if you compare it to Nikon and Canon 24mm f/1.4 counterparts. Another much anticipated lens, the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary is also available for pre-order for $1,089, which is priced right around the same as the Tamron 150-600mm which we highly praised in our in-depth review. Both lenses are expected to ship around March 20, 2015.
If you are curious to see how the Sigma will do compared to the Nikon 24mm f/1.4G, just take a look at the below MTF graphs from both:
Based on the above MTF data, we can see that the Nikon definitely has less resolving power at maximum aperture, delivers less contrast and does not do as well in the corners. The Sigma 24mm f/1.4 Art is super sharp in the center and its performance drops towards the mid-frame pretty quickly, but it is no worse than the Nikkor. There seems to be a bit more pronounced field curvature, but it probably diminishes greatly as you stop down. I expect the Nikon 24mm f/1.4G to be a bit better at rendering bokeh, but at such a wide angle, bokeh characteristics are not super important anyway. If you do not know how to understand the above charts, see my detailed guide on how to read MTF graphs.
This is what I meant when I said that the lens delivers tremendous value. I can already see that the Sigma 24mm f/1.4 Art will be a super popular lens and I wouldn’t be surprised to see both Nikon and Canon drop prices on their 24mm f/1.4 lenses, or few people will be buying those. Great job Sigma, you did it again!
I expect the Sigma 24mm f/1.4 Art to be super popular for astrophotography, landscape photography, event photography, environmental portraiture and many other needs. It is a truly versatile lens – I love my Nikon 24mm f/1.4G, but might have to sell it in favor of the Sigma, or the new Nikkor 20mm f/1.8G, depending on how these lenses stack up at f/1.4-f/1.8. Wide open performance is very important for astrophotography, but I also like the extra 4mm of wider coverage on the 20mm f/1.8G. It will be a tough choice! Cannot wait to get my hands on the Sigma 24mm f/1.4 Art to put it head to head against the Nikon 20mm and 24mm lenses…
