Kirk Sch­warz dis­cov­ers if this is the new go-to lens for Sony’s E-mount.

The new go-to for Sony’s E-mount.

THIS 28-75MM f/2.8 marks Tam­ron’s first out­ing for Sony’s full-frame Al­pha sys­tem. Boast­ing a slightly less tra­di­tional fo­cal length than your stan­dard 24-70mm, it of­fers a wider f/2.8 aper­ture, huge weight re­duc­tion and size­able price drop over Sony’s 24-70mm f/2.8 G Mas­ter. How­ever, less is not al­ways more, so we were in­trigued to see how well the Tam­ron man­aged to per­form out in the field.

Per­for­mance

As any­body who has bought one of the lat­est Tam­ron lenses will tell you, the com­pany is do­ing some great things. This walk­a­bout lens fea­tures a con­stant wide f/2.8 aper­ture, newly de­vel­oped RXD (Rapid ex­tra-silent step­ping Drive) AF mo­tor and weather seal­ing, all of which help give it a wide ap­peal.

The build qual­ity, while still very re­spectable, feels as though it’s been geared more to­wards light­ness than rugged­ness, which isn’t a bad thing. It fea­tures 12 el­e­ments in 15 groups and nine rounded di­aphragm blades for smooth bokeh, and weighs a very re­spectable 550g. There are two large and smooth rings for fo­cus­ing and zoom­ing, though there is a dis­tinct lack of ex­ter­nal con­trols, which keeps it very sim­ple to use. Af­ter test­ing, we have to say the sharp­ness of this lens is ex­cel­lent. Wide-open or stopped down, the cen­tre dis­plays fan­tas­tic re­sults, with the cor­ners show­ing an equal level of de­tail. There is slight vignetting at f/2.8, but this com­pletely dis­ap­pears beyond f/4. You may also no­tice very slight dis­tor­tion at ei­ther end, though this too can be over­come eas­ily with some quick post-pro­cess­ing.

Aut­o­fo­cus per­forms at a re­spectably nippy rate. The new RXD mo­tor means it’s vir­tu­ally silent and very re­spon­sive when paired with Sony’s amaz­ing phase de­tec­tion AF, and we didn’t find any­thing want­ing.

How­ever, the real al­lure comes in the 336g weight re­duc­tion against Sony’s ver­sion, not to men­tion the in­cred­i­bly at­trac­tive £1100 price dif­fer­ence.

Ver­dict

Tam­ron’s first out­ing for Sony seems to be an over­whelm­ing suc­cess. Not only is this lens

sharp and op­ti­cally very im­pres­sive, it’s also light and easy to use. Although we’d have pre­ferred a more solid build qual­ity, the sac­ri­fice for light­ness isn’t a deal breaker.

It’s also rea­son­ably priced, mak­ing it a great op­tion for bud­get con­scious users. Hope­fully this marks the be­gin­ning of a long and beau­ti­ful part­ner­ship.
