|Introduction | Sigma 35mm F1.4 DG HSM A Sony mounted on Sony SLT Alpha 99 | Sigma 35mm F1.4 DG HSM A Sony Versus Sony 35mm F1.4 G both mounted on Sony SLT Alpha 99 | Conclusion|
As the first model in Sigma’s high-grade ART series the 35mm f1.4 HSM A set the bar very high for image quality when measured on Canon and Nikon bodies. The lens is also available in Sony mount, and we couldn’t resist trying it on the excellent Sony A99. Read on to see how well it performs.
For most enthusiasts, whether they like the field of view of a 35mm lens or not, this model will need little or no introduction. In both Canon and Nikon mount versions, it has consistently garnered praise for its build and image quality, not just from us but from just about everyone that has had the opportunity to use one.
The optical construction consists of 13 elements arranged in 11 groups with two aspherical lenses and four SLD (low dispersion) elements. However, there’s one further element using FLD anomalous dispersion glass, that’s similar to the performance of fluorite. The lens also adopts a complex ‘floating’ element design for improved quality at close range and focuses to 30cm. With a filter size of 67mm, a length of 94mm, a sizable 77mm maximum diameter, and weighing 665g, it’s big and heavy lens. All the same, at $899, it undercuts the rival offerings from the big brand names, while few come close to matching its image quality.
