Nikon 1 Nikkor 6.7-13mm f/3.5-5.6 VR & 18.5mm f/1.8 lens reviews: best performing lenses in the rangeBy Kevin Carter - Wednesday June 26 2013 Lens Review
Nikon 1 NIKKOR 18.5mm f/1.8 mounted on Nikon 1V1 Versus Sigma 30mm F2.8 EX DN Sony E mounted on Sony NEX-7:
With a DxOMark score of 13 points, the 18.5mm doesn’t score so well against the Sigma 30mm f/2.8 EX DN, which scores a high 21 points. Like the previously tested 6.7-13mm f/3.5-5.6 model, part of this can be attributed to the lower-pixel count of the Nikon 1 V1 sensor but, in reality, the lens is no sharper than the firm’s zoom. On the plus side, the 18.5mm has low levels of chromatic aberration and good transmission, but it has quite strong distortion for a ‘standard’ or ‘normal’ lens and control of vignetting is really only average.
