Camera - - WHAT’S NEW -

OWN­ErS Of NikON D-SLrS could be for­given for think­ing they’ve been a bit ne­glected by lens-maker Samyang of late… its last few new aut­o­fo­cus mod­els be­ing ex­clu­sively for the Canon EF mount. The good news is that Samyang has just re­leased its first AF lens for full-35mm for­mat Nikon D-SLRs, an F mount ver­sion of the AF 14mm f2.8 ul­tra-wide prime. As with the Canon EF model, the F mount 14mm f2.8 pro­vides Nikon own­ers an af­ford­able al­ter­na­tive to the cam­era branded model, in this case the AF Nikkor 14mm f2.8 ED.

Ex­ter­nally, the bar­rel con­struc­tion em­ploys metal tubes with seal­ing against the in­tru­sion of dust and mois­ture, in­clud­ing a rub­ber gas­ket around the lens mount. On the in­side, the op­ti­cal con­struc­tion com­prises 15 el­e­ments in ten groups which in­cludes no fewer than seven spe­cial types – two as­pher­i­cal el­e­ments, four made from high-re­frac­tive (HR) glass and one with ex­tra-low dis­per­sion (ED) char­ac­ter­is­tics. The as­pher­i­cal types cor­rect for dis­tor­tion and also op­ti­mise the cen­tre-to-cor­ner uni­for­mity of sharp­ness while the oth­ers pri­mar­ily deal with chro­matic and spher­i­cal aber­ra­tions.

Samyang’s ‘Ul­tra Multi Coat­ing’ (UMC) anti-re­flec­tion coat­ings are ap­plied to min­imise ghost­ing and flare. Given the an­gle-of-view of 116.6 de­grees (di­ag­o­nal on a full-35mm sen­sor), the pe­tal-type hood is built-in and there’s no pro­vi­sion for fit­ting screwthread fil­ters. The fo­cus­ing group is in­ter­nal and en­ables a min­i­mum fo­cus­ing dis­tance of 20 cen­time­tres, giv­ing a max­i­mum re­pro­duc­tion ra­tio of 1:6.6. The di­aphragm com­prises seven blades to give smoother out-of-fo­cus ef­fects.

The Samyang AF 14mm f2.8 F is avail­able in Aus­tralia now. Samyang lenses are dis­trib­uted lo­cally by Maxxum Pty Ltd and for more in­for­ma­tion visit www.maxxum.
