Here's our review of the ultra wide Sigma 14mm f/1.8 DG HSM | Art...
Sigma’s Art line-up has fast become one of the most highly regarded lens ranges on the planet. That’s why we’re excited to see the world’s first 14mm f/1.8 prime, with an ultra wide-angle and fast aperture which could make it every astrophotographer’s dream.
The build quality of this glass is superb, with its tough dust and moisture resistant plastic and aluminium design housing 16 elements in 11 groups, as well as 9 rounded diaphragm blades. It features 3 premium FLD and 4 SLD Low Dispersion elements to control chromatic aberration and flare (both of which are near perfectly handled), as well as a newly designed HSM (Hypersonic Motor), which makes for a great autofocusing experience.
While this construction does come at a cost, both financial and heft – the 14mm f/1.8 weighs 1.1kg – its potential for anybody looking to shoot ultra-wide during low-light is undeniable, with the fast f/1.8 aperture, huge front element and 14mm focal length all screaming astrophotography. Despite such a wide aperture, the nature of ultra wide-angles mean you’ll still have a mammoth depth-of-field, allowing for crisp foregrounds, as well as sharp sky details.
Of course, this lens is just as at home with landscape, travel and architecture, which all benefit from such a unique perspective, as well as a large in focus area. One drawback of this lens is the lack of filter ring due to the bulging front element found in many lenses of this focal length. While companies like Lee Filters will inevitably make adaptors to allow you to use filters, these will cost hundreds.
Though it may be costly and not as versatile as Sigma’s other newest release, this lens performs spectacularly. The distortion at the edges of the frame is leagues above other lenses in this focal length, with very little distortion being evident and lines at the extremes of the frame remaining relatively straight. Sharpness is astounding, with the centre at f/1.8 blowing us away and the corners being equally impressive.
We wouldn’t hesitate to recommend this lens.
- Wide maximum aperture
- Ultra-wide focal length
- Superb sharpness
- Image quality
- Heavy and bulky
- Rather limited uses
