The sec­ond gen­er­a­tion of Tam­ron’s fast 70-200mm zoom is a ma­jor im­prove­ment over the orig­i­nal, with high-tech thrills aplenty

The G2 (Gen­er­a­tion 2) edi­tion of Tam­ron’s 70200mm lens is bet­ter built, with metal bar­rel parts, weather seals and a muck-re­sis­tant flu­o­rine coat­ing on the front el­e­ment. In­side, the op­tics are re­vamped with XLD (ex­tra low Dis­per­sion) and LD (low Dis­per­sion) el­e­ments to boost sharp­ness and re­duce chro­matic aber­ra­tions, along with nanos­truc­ture coat­ings to min­imise flare.

Tam­ron’s pro­pri­etary sin­gle-mode VC (Vi­bra­tion Com­pen­sa­tion) sta­bil­i­sa­tion sys­tem has al­ways been im­pres­sive for static shots but less ef­fec­tive for pan­ning. This new lens adds switch­able static and pan­ning modes, plus a third mode that only ap­plies sta­bil­i­sa­tion dur­ing the ac­tual ex­po­sure. As with nikon’s ‘sport’ mode, this avoids a jumpy viewfinder im­age when track­ing er­rat­i­cally mov­ing sub­jects. Bet­ter still, sta­bil­i­sa­tion lives up to its class-lead­ing, five-stop claims.

The aut­o­fo­cus sys­tem is faster and more ac­cu­rate than in the orig­i­nal lens, but still lacks the op­tion of man­ual-pri­or­ity aut­o­fo­cus. The Tam­ron has a shorter min­i­mum fo­cus dis­tance than any of the other lenses, at just 0.9 me­tres, and main­tains good close-fo­cus sharp­ness. elec­tro­mag­netic di­aphragm con­trol is used in both Canon and nikon fit ver­sions, mak­ing the lens in­com­pat­i­ble with the same cam­eras listed in the nikon re­view.

Colour fring­ing and dis­tor­tions are slightly bet­ter con­trolled than in the sigma lens. sharp­ness and con­trast are very sim­i­lar, but the Tam­ron’s bet­ter sta­bil­i­sa­tion sys­tem makes it eas­ier to cap­ture con­sis­tently sharp images in hand­held shoot­ing.
