New f4.0 Speed 70210mm Tele­zoom From Tam­ron

ProPhoto - - NEWS -

For any­body who wants the tra­di­tional 70-210mm tele­zoom in a smaller, lighter and more af­ford­able pack­age, Tam­ron has just added an f4.0-speed ver­sion to its line-up of Di se­ries lenses for full-35mm D-SlRs.

The new 70-210mm f4.0 Di VC uSD (model A034) is around 175 mm in length and weighs it at a very man­age­able 850 grams. It has a weather-sealed ex­ter­nal con­struc­tion with a flu­o­rine coat­ing on the front ele­ment’s ex­posed sur­face to help bet­ter re­pel dust and grease. Hand-held shoot­ing is fur­ther en­hanced by the pro­vi­sion of Tam­ron’s ‘Vi­bra­tion Com­pen­sa­tion’ (VC) op­ti­cal im­age sta­bil­i­sa­tion which is claimed to give up to four stops of cor­rec­tion for cam­era shake.

The op­ti­cal con­struc­tion com­prises 20 el­e­ments in 14 groups and in­cludes three el­e­ments mad from low-dis­per­sion (lD) op­ti­cal glass to min­imise both ax­ial and trans­verse chro­matic aber­ra­tions and there­fore en­hance sharp­ness. Tam­ron says that its new 70-210mm f4.0 zoom de­liv­ers a “… crisp and clear im­age qual­ity across the en­tire zoom range”.

The lens’s fo­cus­ing group is in­ter­nal and is the zoom­ing group so the length of the lens does not change dur­ing ei­ther oper­a­tion. The min­i­mum fo­cus­ing dis­tance is 95 cen­time­tres which gives a max­i­mum mag­ni­fi­ca­tion ra­tio of 1:3.1 (close to onethird life­size) which Tam­ron claims this is the high­est in its class. Aut­o­fo­cus­ing is via Tam­ron’s ‘ul­tra Sonic Drive’ (uSD) and a full-time man­ual over­ride is pro­vided. Dual high-per­for­mance ‘mPu’ mi­cro­pro­ces­sors are ded­i­cated to the im­age sta­biliser and aut­o­fo­cus­ing op­er­a­tions for in­creased speed and re­spon­sive­ness.

The new 70-210mm f4.0 is com­pat­i­ble with Tam­ron’s TC-X14 1.4x and TC-X20 tele­con­vert­ers which give zoom­ing ranges of 98-294mm and 140-120mm re­spec­tively. It’s also com­pat­i­ble with the TAP-In con­sole which en­ables the cus­tomis­ing of cer­tain set­tings and the down­load­ing of firmware up­grades. A tri­pod-mount col­lar with an Arca-Swiss type mount­ing plate is avail­able as an op­tional ac­ces­sory.

The Tam­ron 70-210mm f4.0 Di VC uSD will be avail­able lo­cally from April in ei­ther Canon or Nikon mounts. lo­cal pric­ing is yet to be an­nounced. For more in­for­ma­tion visit www.tam­
