Sigma 24mm 14 Art Nikon Vs Sigma 20mm 18
This is an in-depth review of the Sigma 24mm f/1.4 DG HSM Art lens that was appear in Feb of 2015. Being a professional-grade broad-angle lens, the Sigma 24mm f/1.4 Art was made to challenge similar offerings from both Nikon and Canon, merely at a much lower price point. Previously, Sigma had a lot of success with its Fine art-series lenses such every bit the 35mm f/1.4 Art, so it made sense that the company would go along to brand like class lenses as peachy, upkeep-friendly 3rd-party alternatives.
Without a doubt, Sigma did succeed with making the 24mm f/1.iv Art a remarkable lens with very impressive sharpness characteristics, something lenses like the Nikon 24mm f/1.4G struggle with when shooting at the wide apertures on high-resolution cameras. And with its MSRP of $850, it simply makes other similar-form lenses await expensive in comparison. However, the lens does have its weaknesses that are worth looking into, which is something we will explore in particular in this review.
I had a few encounters with this lens in 2015 and 2016 when traveling domestically and internationally, then aside from being able to utilize it for extended periods of fourth dimension, I take also been able to test a few samples of it to make sure that I did non deal with any sample variance bug, particularly when measuring the optical functioning of the lens. Sadly, I have not had a take a chance to actually review the lens due to my busy schedule until now.
It is clear that Sigma was aiming high when designing the 24mm f/i.4 Fine art lens. With its impressive optical formula comprising of a total of 15 elements in 11 groups, four of which are low dispersion, three of which are depression-dispersion (FLD) and ii of which are of aspherical blazon. That's a lot of loftier-quality glass to utilize in a lens! In comparison, the Nikon 24mm f/1.4G has a full of 12 elements in 10 groups, two aspherical and only two low dispersion glass elements. As a effect, the Sigma 24mm f/1.four Art obviously gained some size and mass – the lens is both bigger and heavier than its Nikon counterpart. However, a few millimeters and grams hither and in that location should not upset a potential heir-apparent, since the performance gain is definitely worth it. If i is interested in going for a smaller and lighter 24mm lens, the Nikon 24mm f/1.8G would be a better candidate, at almost half the weight.
Because that there are other, more versatile lens options such as the Sigma xiv-24mm f/2.8 Art, who is a lens like the Sigma 24mm f/i.4 Art aimed for? Primarily, such lenses are aimed for photographing / video recording events and portraits, where the photographer or videographer wants to capture individual or group portraits in low-light environments. The difference of ii stops between an f/1.4 and an f/2.viii lens is a pretty big deal, just like shooting at ISO 800 vs ISO 3200. Being able to shoot at such large apertures with a wide bending lens also allows photographers to isolate subjects from the background, creating pleasing images with their subjects popping out of the scene. Withal, the lens tin also exist used for other types of photography such as landscape, astro and travel photography.
In this review, I volition do my all-time to provide a thorough analysis of the Sigma 24mm f/i.iv DG HSM Fine art, along with epitome samples and comparisons to other wide-angle lenses with the aforementioned focal length, such as the Nikon 24mm f/1.4G, Nikon 24mm f/1.8G and Samyang 24mm f/1.4.

Build Quality and Treatment
The Sigma 24mm f/i.iv Fine art is built very well, similar to other Sigma Art-serial lenses – information technology has a overnice all-metal barrel and a metal mount. The lens feels solid in hands and balances nicely on both lighter and heavier DSLRs. Focusing with the Sigma 24mm f/1.4 Fine art is a breeze – the focus ring is located on the front end of the lens barrel and it is very smooth and piece of cake to rotate, making the lens a great candidate for manual focusing. The front end chemical element of the lens does not extend or rotate during focusing. Be warned though, if you have been shooting with Nikon lenses, keep in mind that all Sigma lenses rotate in the opposite direction like Canon lenses practice. Not an issue for virtually people, merely tin take some time to get used to.
The Sigma 24mm f/1.four Art features a 77mm filter thread, which is what i would usually see on all professional-grade lenses. There is a switch on the side of the lens to move betwixt Autofocus and Manual Focus, like to the switches plant on Nikkor lenses. The lens comes with a plastic petal blazon hood that stays deeply locked once mounted on the front of the lens. There is a small plate with the letter "A" on the side of the lens, indicating the "Art" category of the lens.
Unfortunately, but like some of the earlier Sigma Fine art-series lenses, the 24mm f/1.4 Fine art does not accept a rubber gasket on the rear mount. This means that you have to watch out for dust, wet and other debris betwixt the lens and the camera mount or it might make it into the photographic camera (and potentially into the lens). For this reason, I would recommend to try to go on the rear metal mount area clean at all times.
Autofocus Functioning and Accuracy
The Sigma 24mm f/i.4 Art features the same high quality "HSM" hyper-sonic motor constitute on other Sigma lenses, which provides fast and tranquility autofocus performance. I really don't take any complaints with AF speed, but when information technology comes to AF accurateness, I had some issues with the first lens sample. While the lens did well for focusing manually, I had AF accuracy problems when shooting at wider apertures. For example, accept a look at the below prototype:
That'southward a great moment, except the photo is very out of focus. I did not imagine that AF accuracies could accept been this bad – I had to punch +20 to get reasonable results, but even then there were all kinds of bug. Thankfully, the Sigma dock was a lifesaver and it did the chore, but this shows just how of import it is to have a properly calibrated lens. If yous are going to invest in Sigma lenses, the Sigma dock is a must-take, period. The second sample was much better, simply information technology also had to take some AF adjustments to it to get the best results.
Information technology is important to betoken out that these issues are not necessarily specific to Sigma lenses – any DSLR lens is prone to AF problems, due to the fashion phase detection autofocus works.
