DxOMark has tested the new Tamron SP 35mm f/1.8 Di VC USD lens for Nikon F-mount (Amazon/B&H/Adorama). This lens is Tamron’s first prime lens released in September 2015. It costs $599 in US, a cheap and great lens from Tamron. According to DxOMark, when tested on Nikon D810, this lens is only one point below 35mm king: Sigma 35mm f/1.4 Art lens. See the DxOMark below:
Tamron SP 35mm F1.8 Di VC USD versus Sigma 35mm F1.4 DG HSM A versus Nikon AF-S NIKKOR 35mm f/1.8G ED
Conclusions from DxOMark:
The Tamron 35mm f1.8 comes close to matching the Sigma 35mm f1.4 in terms of sharpness, and even surpasses it in uniformity at wider apertures, and has lower distortion, vignetting and chromatic aberration. At $600, it’s comfortably more accessible than the Sigma (although you do give up three-quarters of a T-stop); indeed, it’s around the same price as the Nikon 35mm f1.8G ED that it outperforms, particularly with regard to control of chromatic aberration. Add optical stabilization, and theTamron looks like an attractive option.
