Sigma Dg Dn 1424mm F28 Art Versus Sigma 1424 Dslr

The specifications are impressive, simply can a super-wideangle zoom with a super-fast f/2.8 aperture deliver the results pros and ardent amateurs demand?

The Sigma xiv-24mm F2.8 DG HSM Art lens has the correct combination of features to wake upward the artist in any lensman. Information technology truly is a scattering of excitement.

Technical Description
The 2018 TIPA Laurels-winning Sigma 14-24mm super-wideangle zoom is a hefty (40-ounce) technical curiosity that's available in Sigma, Canon and Nikon mounts. Designed for full-frame DSLRs, it works with APS-C sensor cameras as well. Physical dimensions measure 3.8 x 5.3 inches.

The optical formula consists of 17 elements in 11 groups, including three FLD, iii SLD and iii aspherical elements. FLD glass is known to offering outstanding optical performance equal to fluorite. The rounded aperture diaphragm uses 9 blades and delivers excellent bokeh. Antireflection and anti-ghosting lens coating is the Super Multi-Layer type. The discontinuity range is a jaw-dropping fast f/2.8 to f/22.

The maximum aperture is a constant f/2.8, so unlike typical kit-zooms, which darken as they zoom, the Sigma 14-24mm can exist used wide open up at f/two.8 at any focal length within the zoom range. Given that wideangles—particularly super wides like a 14mm—are well suited for shooting indoors in cramped confinements, this fast-fast aperture is a tremendous benefit.

Yeah—it's infrared. I used the Sigma 14-24mm on my IR-but modified Nikon D5000 body with cracking results. Exposure setting was f/8 at 1/160 2d, ISO 200 with bias of -i stop. ©Jon Sienkiewicz

Quick and quiet Autofocus is driven past a Hyper Sonic AF Motor equipped with manual override. Minimum focusing distance is 10.2-inches and that unlocks many versatile applications where you may not take considered using a super-wideangle zoom in the past.

2018 TIPA Award: Best DSLR Wide Angle Zoom Lens
Equally briefly referenced above, the Sigma 14-24mm f/2.eight zoom is the 2018 TIPA Award winner in its category. TIPA, as you probably know, stands for Technical Paradigm Printing Association and is a highly regarded, totally impartial honor.

Powerful Zoom Range
Even if we set aside the huge benefits of the constant f/ii.8 maximum aperture, the Sigma 14-24mm zoom is versatile and heady because of the useful and creative range of focal lengths it covers. It'southward a given that 24mm lenses are an important tool for whatever lensman, and extending the wideangle coverage to 14mm is cipher short of scenic. The Angle of Coverage is 114.2° to 84.1° and while near people cannot mentally visualize what that means, i expect through the viewfinder shows yous all you lot need to know.

If yous're looking for an fifty-fifty wider zoom range, Sigma also offers a 12-24mm f/4 super-wideangle zoom that I reviewed hither.  Deciding which is more important—the extra zoom range of the 12-24mm f/iv or the faster aperture of the fourteen-24mm f/2.8—is a delightful dilemma. Both lenses are superb and ideal in their own way. Having used both in a variety of situations, I lean heavily toward the faster f/finish. If I had any doubt forth the way, it immediately disappeared when I did some dark shooting at a local street carnival. The extra stop (which after all, does represent a 100% increase) led to more artistic opportunities.

Loftier Performance
If you lot're looking for pincushion or butt distortion, you won't find it here, I'm happy to say. No lens is 100% distortion free, but the Sigma fourteen-24mm f/ii.eight comes amazingly close when focused at infinity. In addition to delivering brilliant and sharp images on my full-frame Nikon D800, I plant the lens to be rectilinear—directly lines are rendered as straight lines with no visible barrel or pincushion distortion. This is particularly remarkable because of the farthermost wideangle focal length.

Historically, super wideangles tend to distort in i dimension or some other. Role of the cause of apparent distortion is frequently the mistake of the user. If you point a wideangle off-centrality and up, for case, straight lines are likely to bend and parallel lines might converge plenty to make Einstein rethink his explanation of the Infinite Time Continuum. Then proper use is important. That said, some lenses misconstrue no matter how conscientious the user is. With the Sigma fourteen-24mm you lot commencement out with goose egg distortion, so whatsoever bent lines are your responsibility.

In the field I found sharpness, color rendition and contrast to exist outstanding and consistent from shot to shot. Daytime performance in normal lighting conditions was excellent, simply the existent strength of this lens becomes obvious when shooting under depression light or even night conditions. As you tin gauge from the accompanying photos, the Sigma xiv-24mm f/two.8 zoom delivered high quality images in every respect.

Build Quality
Sigma Art Lenses and this 14-24mm f/2.8 model in detail have a solid feel and operate smoothly. Tactile feedback tells yous that you're holding a precision musical instrument. The zoom ring turns hands with only plenty resistance and the Hyper Sonic Motor (HSM) autofocus zips quietly and quickly as you etch. The lens mount is made of contumely and is weather-resistant. Overall, the build quality is excellent.

Conclusion
I tin can think of any number of applied applications for the Sigma 14-24mm f/ii.eight super wideangle zoom, from indoor real manor photography, to world travel, to close groups and weddings; but the creative possibilities are even more intriguing. The combination of a very broad 14mm focal length plus a very fast f/ii.8 discontinuity and close-focusing distance of 10.2 inches suggests almost unlimited creative pursuits, including extreme street photography, abstract architecture and environmental portraiture.

Available in Canon, Nikon and Sigma DSLR mounts, the Sigma fourteen-24mm f/2.8 comes with a 4-year warranty and has a street price of $1200.
