Tamron 28-75mm f/2.8
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.
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.
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.
