Camera - - CONTENTS -

We’re start­ing the run up to this year’s Pho­tok­ina in Septem­ber, but there’s still plenty hap­pen­ing right now with Fu­ji­film’s lat­est X mount mir­ror­less cam­era, the X-T100; Panasonic’s new ruggedised Lumix FT se­ries com­pact (now with an EVF); Has­sel­blad’s widest-an­gle lens ever (it’s for the X1D mir­ror­less sys­tem); the ar­rival of Tam­ron’s first zoom for the Sony FE mount; the re­turn of Ri­coh’s GRII; and much more.

months ago, Tam­ron’s first ac­ces­sory lens for Sony’s FE mount is now avail­able in Aus­tralia. The 2875mm f2.8 RXD zoom is a Di III se­ries lens (Tam­ron’s des­ig­na­tion for lenses for ful­l35mm mir­ror­less cam­eras) and em­ploys a new aut­o­fo­cus­ing drive called ‘RXD’ which stands for Rapid eX­tra-Silent Step­ping Drive. Step­ping mo­tors are be­com­ing more fre­quently used for aut­o­fo­cus­ing sys­tems be­cause they’re not only very quiet, but pro­vide the smooth­ness which is es­pe­cially im­por­tant when shoot­ing video.

The Tam­ron lens sup­ports Sony’s ‘DMF’ (Di­rect Man­ual Fo­cus) func­tion which pro­vides a full-time man­ual over­ride of the aut­o­fo­cus­ing. It also sup­ports Sony’s in-cam­era corrections for vi­gnetting, chro­matic aber­ra­tions and dis­tor­tion.

The min­i­mum fo­cus­ing dis­tance is 19 cen­time­tres at 28mm and 39 cen­time­tres at 75mm which gives a max­i­mum re­pro­duc­tion ra­tio of 1:4. It mea­sures 117.8 mm and weighs in at 550 grams.

The FE mount 28-75mm f2.8 Di III RXD zoom (a.k.a. Model A036) fea­tures a weather-sealed ex­ter­nal con­struc­tion with a flu­o­rine coat­ing on the ex­posed sur­face of the front el­e­ment to help bet­ter re­pel mois­ture and grease. The op­ti­cal con­struc­tion com­prises 15 el­e­ments in 12 groups which in­cludes one XLD (eX­tra Low Dis­per­sion) type, one LD (Low Dis­per­sion) type and three as­pher­i­cal el­e­ments – one glass­moulded type and two hy­brid types. Col­lec­tively, th­ese spe­cial el­e­ments cor­rect for both dis­tor­tion and chro­matic aber­ra­tions. The new lens also has Tam­ron’s BBAR (Broad Band Anti Re­flec­tion) multi-coat­ing to cor­rect for both ghost­ing and flare.
