Typ­i­cal of the Tam­ron lenses on test, the op­ti­cal sta­bi­lizer is very ef­fec­tive for static shots, but less ben­e­fi­cial when pan­ning. Wideaper­ture sharp­ness is pretty poor at long zoom set­tings, par­tic­u­larly to­wards the edges and cor­ners of the frame. Rep­re­sent­ing an up­grade over the orig­i­nal Tam­ron 18-270mm, this re­vamped edi­tion nev­er­the­less harks back to 2010, mak­ing it one of the old­est lenses on test. Even so, it sports an im­pres­sive 15x zoom range with an ‘ef­fec­tive’ fo­cal length of 405mm at the long end.

Im­prove­ments over the pre­vi­ous in­car­na­tion in­clude the fit­ment of a PZD (Piezo Drive) aut­o­fo­cus sys­tem. It’s es­sen­tially an ul­tra­sonic mo­tor-based sys­tem, sim­i­lar to that used in both Sigma lenses on test.

De­spite its up­sized zoom range, this lens is ac­tu­ally phys­i­cally smaller than the Tam­ron 18-200mm, although it’s 50g heav­ier – mostly down to it hav­ing a metal, rather than plas­tic, mount­ing plate. It’s the only Tam­ron on test that lacks a weather-seal ring on its mount.
