Sigma 100 400mm F 5 6 3 DG DN OS C Review | 54 Data compared

The Sigma 100-400mm F5-6.3 DN OS Contemporary lens for Sony FE and Leica L-mount is a highly competitive, budget-friendly telephoto zoom designed for wildlife, birding, and sports photography. Weighing 1135g, it is significantly lighter and slimmer than its main competitor, the Sony 100-400mm GM, making it excellent for traveling light. Optically, the lens performs exceptionally well, delivering strong contrast and sharpness that actually optimizes at the 400mm focal length, rivaling far more expensive alternatives. Its stepping motor provides fast, quiet, and smooth autofocus tracking that supports Sony's Eye AF, a major upgrade over the sluggish autofocus found in Sigma’s older DSLR version. Additionally, it features a robust rubber lens mount gasket, effective 4-stop optical stabilization, and dual "twist" or "push-pull" zoom mechanics. However, the lens does compromise on a few features to achieve its low price point. A notable disadvantage is that the variable aperture drops very quickly, hitting F5.6 at just 113mm and reaching its dimmest F6.3 aperture by 235mm, limiting its usefulness in poor light. While the lens barrel is physically prepared to accommodate a tripod collar, the...

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary is a completely redesigned "light bazooka" engineered specifically for full-frame Sony E and Leica L-mount mirrorless cameras. Weighing just 1,135g to 1,140g depending on the mount, this compact and lightweight lens offers a powerful super-telephoto range that is highly portable compared to heavy DSLR counterparts. It delivers highly impressive sharpness across the entire image frame—even when shooting wide-open—and keeps color fringing completely negligible due to an upgraded optical path featuring a premium FLD element. Handling is excellent, boasting a rapid stepping motor autofocus system, an autofocus range limiter, a customizable AF-Lock button, 4-stop optical stabilization, and a unique dual-action mechanism that allows for both twist and push-pull zooming. Despite its stellar performance, the lens has a few notable drawbacks. Its maximum aperture rating becomes fairly narrow at f/6.3 at the longer focal lengths, making it a bit of a struggle to achieve a tightly blurred background at the short end. While Leica L-mount users enjoy teleconverter and USB Dock support, Sony E-mount shooters face the major con of having absolutely no compatible...

The Sigma 100-400mm f/5-6.3 DG DN OS for Sony E-mount offers a high-value alternative to Sony’s first-party version for less than half the price. The reviewer praises the lens for its solid, mostly metal build quality and reliable weather sealing that survives rainy conditions. Its hardware features are highly functional, including an auto-focus lock button, a focus range switch, and multiple image stabilization modes. Optically, the lens delivers competitive performance with fast autofocus that hunts less than other mid-tier zooms, making it an excellent entry point for hobbyist wildlife, street, and outdoor photographers. However, the lens has notable trade-offs when compared to the premium $2,499 Sony alternative. A key con is its slower f/5-6.3 aperture range, which loses a third-stop of light against Sony's f/4.5-5.6 range and limits low-light performance. Additionally, its minimum focusing distance grows progressively longer up to 63 inches at the 400mm end, making it less versatile for close-up macro shots. The autofocus accuracy, while good, falls slightly short of the precision needed by tracking professionals. Finally, it is heavy at 2.5 pounds, conspicuous for street photography,...

The Sigma 100-400mm f5-6.3 DG DN OS Contemporary lens for L Mount is a highly manageable, compact, and affordable long-range telephoto zoom designed specifically for full-frame mirrorless cameras. Constructed from a robust blend of polycarbonate and metal, it features a durable brass bayonet mount equipped with dust- and splash-proof sealing. Weighing 1,135 grams and measuring 197.2mm in its shortest state, the lens is exceptionally lightweight for its focal range, making it comfortable for full-day handheld photography walks. It delivers excellent overall image quality with high center sharpness, strong contrast, minimal flare due to a Super Multi-Layer Coating, and smooth bokeh from a 9-blade rounded diaphragm. Additionally, it features up to 4 stops of optical image stabilization, a quiet stepping autofocus motor, a zoom lock switch to prevent zoom creeping, and compatibility with 1.4x and 2x teleconverters exclusively on the L Mount version. The reviewer highlights several notable pros, emphasizing its high-quality construction, compact size, and effective optical stabilization. Its affordability is another major advantage; priced at $949, it serves as a budget-friendly alternative to much more expensive L-mount long zooms...

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary is a mirrorless telephoto zoom lens that offers strong value, pricing around 950 USD/EUR for Sony E and L-mounts. On the positive side, it features an upgraded metal design near the mount, a fast and noiseless stepping autofocus motor, an effective optical image stabilizer, and a unique "Dual-action" zoom mechanism allowing push/pull operation. Optically, the lens delivers decent resolution across its range, peaking with highly commendable sharpness in the low-to-mid focal lengths and low lateral chromatic aberrations. It is also highly praised for being relatively lightweight and compact for a 400mm lens.

In his review for Sigma South Africa, wildlife photographer Trevor McCall-Peat praises the Sigma 100-400mm f/5-6.3 DG DN OS Contemporary lens as a lightweight, compact option delivering sharp images, impressive contrast, and fast, quiet autofocus. The lens is lauded for its excellent image stabilization and portability, making it ideal for handheld, all-day shooting, even at 400mm. Cons noted in the review include the lack of a bundled tripod collar (requiring the optional TS-11), the absence of full weather-sealed construction found in higher-end models, and a narrower f/6.3 maximum aperture at the telephoto end that limits extreme low-light performance. Overall, the review positions it as a highly capable, budget-friendly choice for nature photography.

The PCMag review highlights the Sigma 100-400mm F5-6.3 DG DN OS Contemporary as an exceptional, budget-friendly ($949) telezoom for full-frame mirrorless cameras, boasting a lightweight, compact design and sharp image quality. It delivers fast, quiet autofocus, and effective optical stabilization, making it ideal for handheld sports and wildlife photography. However, the lens has drawbacks, including noticeable pincushion distortion, vignetting at wide apertures, and a significant physical extension when zooming. Furthermore, the lens lacks comprehensive weather sealing, omits a tripod collar in the box, and blocks the use of teleconverters for Sony E-mount users.

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary lens is a lightweight, full-frame mirrorless zoom that offers highly impressive, sharp image quality, efficient autofocus, and four stops of image stabilization. Key pros highlighted include its compact, hand-holdable design, durable construction with on-lens controls, and an affordable price point compared to competitors. Conversely, the lens has a variable f/5-6.3 aperture, which can hinder low-light performance and limit shutter speeds for action, alongside limited headroom to avoid diffraction. Additionally, while featuring a dust-and-splash-proof mount, it lacks full-body weather sealing and does not support teleconverters on E-mount versions.

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary lens for Fujifilm X-mount cameras stands out as a highly portable telephoto option, offering a 150-600mm full-frame equivalent focal length in a remarkably compact and lightweight body. Reviewer Pete Coco praises the lens for delivering sharp, high-contrast images with exceptional color rendition across all focal lengths. When tested with the Fujifilm X-T5, its autofocus tracking proved silent, fast, and highly accurate, flawlessly capturing a 15-frame-per-second sequence during a college soccer match. Additionally, handling is improved by a dual-action mechanism that allows users to adjust framing by either using the zoom ring or simply pushing and pulling the front barrel. Despite its high build quality and budget-friendly price tag, the lens does have a few drawbacks. Its slow f/5 to f/6.3 maximum aperture limits light intake, though it can still achieve pleasing bokeh separation. The reviewer noted some visible purple fringing when shooting under harsh midday sunlight and found that the color profile leaned slightly cooler compared to native Fujifilm glass. Performance also varied by camera generation; autofocus tracking was far less "sticky"...
