The Sigma 10-20mm f3.5 EX DC HSM is an ultra wide-angle zoom lens suitable for anyone interested in Landscape Photography, Travel Photography and architecture for example.
It is worth noting however that this lens is only designed for APS-C or DX sized Nikon DSLR cameras, meaning it is not compatible with full-frame (FX) cameras such as the Nikon D850. The 10-20mm f/3.5 offers photographers extreme to wide focal lengths. Its compact and lightweight construction make it a comfortable lens to use all day, paired with a DX DSLR such as the Nikon D7500 or D3400.
The Hyper Sonic Motor (HSM) of the Sigma 10-20mm delivers fast, accurate and near-silent autofocusing. With a minimum focusing distance of 24cm, this lens will produce a near fisheye photography look with an ultra-wide field of view when taking portraits for example. It also offers manual override so that users can take over control of focusing without having to physically turn off the autofocusing function. One of the key features that sets this lens apart from its competition is that it has a constant f/3.5 aperture. This gives photographers total control over their aperture settings as they progress through the lens’ zoom range.
Both Extraordinary Low Dispersion (ELD) Super Low Dispersion (SLD) glass elements are included in the structure of this lens, as well as two hybrid Aspherical lens groups. These quality elements and specialised lens coatings combine to minimise the impact of chromatic aberrations, flares and ghosting, boosting overall image resolution and clarity. Additionally, the 7-blade aperture construction of this lens also helps to deliver attractive out-of-focus highlights as the lens creates attractive separation between the intended subject and the background when shooting at wider apertures.
A good choice for events photographers and filmmakers, the Sigma 10-20mm f/3.5 is a fantastic alternative to native lens options at this focal range and a solid investment for anyone who is keen to build their kit.
