Review: Sigma 105mm F1.4 DG HSM Art Lens


12.24.2018 Tech

For the love of BokehThe Sigma Photo 105mm F1.4 DG HSM Art lens is part of the company’s Global Vision line of Art, Sport, and Contemporary lenses. It is a solidly constructed, large-aperture, large-bodied (for its focal length) autofocus lens designed for full-format (24x36mm) cameras. And like the other Sigma Art lenses, it delivers superb optical performance at a reasonable price. One thing about Sigma’s Art series lenses is that they make you feel as if the people who make them truly... Continue Reading >

Review: Sigma 70mm F2.8 Macro Art Camera Lens


November 2018 issue Tech

Macro photography reveals the art of the smallMacro photography is always tricky, but when done well, it reveals a world our unaided eyes cannot perceive. Macro photography is hard because it comes with its own set of problems: The depth of field is shallow (unless you use focus stacking), and the small scale makes lighting control difficult. True macro photography covers the 1X to 10X magnification range of a subject. Lenses that natively magnify greater than 1X, like Canon’s MP-E 65mm... Continue Reading >

Pro review: Sigma 16mm F1.4 DC DN Contemporary lens


8.25.2018 Tech

Good thing, small packageOnce again Sigma has produced a high-quality lens, and it’s not even part of the company’s acclaimed Art series. The Sigma 16mm F1.4 DC DN is part of the Contemporary lineup for APS-C and Micro Four Thirds system cameras.  Even though it isn’t an Art lens, it performs on the same level—sharp with excellent flare and ghost suppression and pleasing bokeh. I saw no noticeable chromatic aberrations or geometric distortion. Used with APS-C cameras, it covers the... Continue Reading >

Review: Sigma scores a home run with this lens


June 2018 issue Tech

Is it silly to even discuss the optical performance of the Sigma 24-70mm F2.8 DG OS HSM lens? Pretty much. Like all of the Art series lenses, Sigma hits an upper deck center field home run with this one. After working with it extensively for a couple of months, I’m clear on one point: This is one of the very best 24-70mm zooms you can buy. Even on the notoriously picky 50-megapixel Canon EOS 5DS it performs beautifully—sharp, virtually flare free, and masterfully corrected for both... Continue Reading >

Straightforward: Sigma SD Quattro H Review


April 2018 issue Tech

At a time when major manufacturers seem to be packing every conceivable function into their camera bodies, it’s refreshing that one company is producing a camera with extremely high resolution, simple operation, and a competitive price. The company is Sigma, and the camera is the Sigma sd Quattro H. What it does, it does extremely well, and what it does not do, you may not need. Indeed, its simplicity and ease of use remind me of the days of shooting with 35mm film.UNCONVENTIONAL... Continue Reading >

Sigma sd Quattro H delivers high image quality

March 2017 issue Tech

The Sigma sd Quattro H is the first camera to feature the newly developed APS-H size Foveon X3 Quattro direct image sensor with 51-megapixel equivalent resolution (1.3x crop factor). Three layers of photodiodes—red, green, blue—means there’s no need for a low-pass filter to correct for interference caused by a color filter array. This results in exceptional detail and nuanced color gradations. DNG raw is supported for compatibility with Lightroom and other programs, along with Sigma’s... Continue Reading >

Product review: Sigma Sport camera lens is super glass


March 2017 issue Tech

Advances in the design of super-telephoto prime and zoom lenses mean that sports, wildlife, and bird photographers have never had a better selection of glass to choose from. Sigma Corp. released its 150-600mm F5-6.3 DG OS HSM Sports lens a year ago, and I was excited to receive it for review recently so I could compare its performance to that of the AF-S Nikkor 200-500mm f/5.6E ED VR and the AF-S Nikkor 200-400mm f/4G ED VR II (“Big, Heavy, Awesome,” July 2015).Sigma Sports lenses are...

Lens trifecta


January 2016 issue Tech

Sigma 24-35MM f2 DG HSM art lensExceptional quality, short focal length range, large-aperture zoom, great price—who doesn’t yearn to find that trifecta in a lens? Sigma’s 24-35mm F2 DG HSM Art lens is a winner in all three heats. But it comes with some cost: The zoom range isn’t large, and it’s not what anyone would call a small or lightweight lens.With high-end wide-angle zoom lenses the focal length range is around 2.5X or less; anything beyond that seriously tests the limits of...
