Overview of the Sigma 100-400mm f5-6.3 DG OS HSM Contemporary Lens – Canon EF Mount

Blending a long reach with a convenient form factor, the Sigma 100-400mm f5-6.3 DG OS HSM Contemporary Lens is a telephoto zoom within Sigma‘s Contemporary series that blends both a refined optical design with a compact and lightweight physical construction. On the optical front, this zoom utilizes four SLD glass elements to noticeably reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy, and a Super Multi-Layer Coating has also been applied to increase contrast when working in strong lighting conditions.

Balancing the optics, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. An Optical Stabilizer also benefits handheld shooting by minimizing the appearance of camera shake for sharper imagery. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments; both twist and push-pull zoom mechanisms are available for improved control over field of view; and a brass bayonet mount also offers rigidity and mounting precision.

Optical Quality

It’s a common feature on Sigma lenses that glass treatment will help you capture some beautiful imagery. This lens designed to feature stunning optical quality throughout the entire 100-400mm focal range. The large focal length is accompanied by several glass elements and coatings; it’s constructed from 21 lens elements in 15 groups, including four Special Low Dispersion (SLD) glass elements that help to reduce colour fringing and chromatic aberrations which in turn increase clarity and colour accuracy. Also, Sigma has applied a super-multi-layer coating which is designed to minimise lens flare and ghosting. These coatings also contribute to contract-rich, colour-neutral photos, even when you find yourself in backlit conditions.

OS & HSM

To accompany the beautiful optics of this lens, Sigma two features that enable smooth, fast and shake-free operation. First of all, is the addition of an integrated Hyper Sonic Motor (HSM) which allows your autofocusing to be quick and quiet; a complimentary feature for a telephoto lens such as this stealth can be key to capturing the best shot. This motor is enhanced with an updated AF algorithm that further smooths focussing, and what’s more, the HSM does allow for full-time manual control at any given moment. Sigma also has featured a redeveloped gyroscopic sensor and exclusive algorithm which together, create an all-new optical stabilisation unit. You’ll find that held in both a vertical or horizontal position, the acceleration sensor will detect camera shake in any horizontal, vertical, or diagonal direction.

User Experience

The lens has been designed in such a way that is can cater to a surprising amount of situations that you might find yourself in. From a glance, this is a telephoto lens; the 100-400m coverage will allow you to capture a wide range of faraway subjects. However, as much as it is a telephoto lens, it has a minimum focal distance of 160cm and a maximum magnification ratio of 1:3.8, allowing it to become a certified macro-ready-lens. The lens is also there when you need quick control to change your angle of view. It features an integrated push/pull zoom mechanism in addition to the standard twist zoom ring. By including this feature, it enables you to instantly change your field of view to capture that perfect shot. This will also operate when attaching the exclusive lens hood that comes with this lens, only adding to the already impressive versatility.
