Feel the width… and the qual­ity. Here’s how the lenses fared in our ex­haus­tive lab

Samyang 14mm f/2.8 IF ED UM C Sigma 20mm f/1.8 EX DG Nikon AF-S 18-35mm f/3.5-4.5G ED Sigma 12-24mm f/4.5-5.6 DG HSM II

Sharp­ness drops off at the short end of the zoom range but beats the Nikon 16-35mm at mid to long zoom set­tings.


Along with its ex­tra-wide an­gle of view comes no­tice­able bar­rel dis­tor­tion, which also has a rather ir­reg­u­lar shape.


Bar­rel dis­tor­tion at 12mm is well con­trolled, equalling the Nikon 18-35mm and bet­ter­ing the other Nikon zooms.


The 18-35mm gives less bar­rel dis­tor­tion than the other Nikon zooms at their short­est zoom set­tings.


De­spite hav­ing a shorter fo­cal length than the Nikon 24mm, this pro­duces less bar­rel dis­tor­tion, which is im­pres­sive.


There’s very lit­tle colour fring­ing, and the Samyang’s lab score for this al­most matches the very pricy Nikon 24mm f/1.4.

It’s a bit dis­ap­point­ing at f/2.8 but hits its stride at f/4 and re­tains sharp­ness well through the rest of the aper­ture range.

Cen­tre sharp­ness is very good even at wide aper­tures but there’s a real lack of any sharp­ness away from the cen­tre.

Con­sid­er­ing the an­gle of view at 12mm, sharp­ness across the frame is ex­cel­lent, as long as you nar­row the aper­ture a bit.


Per­for­mance for colour fring­ing is the best of any lens in the group, de­spite this one be­ing the least ex­pen­sive zoom.


Fring­ing can be no­tice­able to­wards the cor­ners of the frame at the short­est set­ting, but im­proves at longer lengths.


Along with the ma­jor drop in sharp­ness to­wards im­age cor­ners comes bet­ter news of min­i­mal colour fring­ing.
