Nikon AF-S 20mm f/1.8G ED

The long-awaited up­date to Nikon’s 20mm fixed wide-an­gle

NPhoto - - Test Team -

Nikon pro­duces a wide range of G-type zoom lenses us­ing its ‘silent wave’ aut­o­fo­cus sys­tem, but many of the company’s fixed fo­cal length lenses are older, D-type op­tics. Th­ese have aper­ture rings on the lens and rely on the older, nois­ier screw-drive aut­o­fo­cus sys­tem in the cam­era body – a fea­ture no longer of­fered on D3000or D5000-se­ries cam­eras. Although Nikon al­ready has a 20mm f/2.8 D-type lens, this new 20mm f/1.8G ED brings both faster, qui­eter aut­o­fo­cus and more than a full stop of im­prove­ment to max­i­mum aper­ture. The Nikon AF-S 20mm f/1.8G ED is a su­per­wide-an­gle lens for full-frame (FX) cam­eras but, like all Nikon’s full-frame lenses, it can also be used on DX mod­els, though the ef­fec­tive fo­cal length be­comes 30mm, so it will act like a medi­umwide-an­gle lens rather than a su­per-wide.
