Lens Test: Tamron 70-200mm f/2.8 Di VC USD

Tamron stabilizes a pro favorite

The new image stabilizer seems truly improved.

Among pros, image-stabilized 70–200mm f/2.8 full-frame zooms have become must-own glass. They’re in Canon ($2,499, street), Nikon ($2,397), Sigma ($1,399), and now Tamron’s catalogs ($1,499), and we see them at weddings, sporting events, in portrait studios, and in backpacks. Tamron’s version includes four elements of low-dispersion and one of extra low-dispersion glass. Another boast: Its Vibration Control has been redesigned for better performance.

Not for the faint of wrist, this 3.32 pounder is actually several ounces lighter and about a quarter-inch shorter than the competition. Its nonrotating front ring is nice for lens-mounted filters; the 130-degree manual focus turn is just about perfect (although at a little over a half inch, the MF ring is small); the build is robust, with rubber cowling at the lens mount. There’s no depth-of-field scale, though. (The comparable Sigma has two.)

In the field, we were bowled over by the near-silent USD focusing motor. On our Canon EOS 5D Mark III, AF was rapid, silent, and sure. On our optical test bench, the lens produced Excellent-range SQF numbers for sharpness and contrast at 70mm and 135mm. Like most zooms in this category, though, it dipped to Very Good at 200mm. (Only the Nikon held onto top sharpness at 200mm.)

In our DxO Analyzer 4.1 tests, distortion control proved best in its class: it produced only Slight distortion at 70mm and 200mm (0.11% barrel and 0.18% pincushion, respectively) and Imperceptible (0.09%) pincushioning at 135mm.

In our tests, three users averaged about 3.5 stops of additional handheld sharpness. Tempted by the nonstabilized version? It is a half-pound lighter, costs half as much, offers much more subject magnification, and takes sharper images at 200mm. But you’d miss out on a whole lot of handheld shooting. For us, money aside, it’s a no-brainer.

The focus in this photo is on the purple ball ornament to the left of this frame. The light was coming from a large window to the right of the scene. We'll have to test it in the lab, of course, but right out of the box it seemed pretty sharp.

Back at Photokina, Tamron announced their intentions to release a new 70-200mm F/2.8 VC lens and they've made good on that promise. I spent some time shooting with the new lens on a fresh-out-of-the-box Canon EOS 6D. All of the images were shot in JPEG mode with standard image settings.

Sadly, the birds didn't feel like doing any flying during the 15 minutes or so I had to photograph them for a hardcore speed test, but the focusing is very quiet, which is a plus.

In this one, you can clearly see the flare happening, but I actually find it kind of appealing. The loss of contrast is a bit much, though. This was shot without the included lens hood.

Zoomed all the way out, it seems like the focal range is a bit shorter than I'd expect a 70-200mm lens to be.

We'll have to test it for sure in our lab, but it didn't have that 70-200mm feel I'm used to. Looks like the folks over at Lensrentals found the same thing.
