Tamron Tips the First 17-50mm F4 Full-Frame Zoom Lens

Today Tamron is teasing a new full-frame lens, set to be sold exclusively for Sony's full-fame mirrorless system, the 17-50mm F4 Di III VXD. The small starting focal length means it covers an extra wide angle, almost as broad as current options like the Sigma 16-28mm F2.8 Contemporary or Sony FE PZ 16-35mm F4 G, but with more zoom power than either.

Wide zooms are popular picks for subject matter like architecture and landscapes, but most zoom in just tight enough for environmental portraits. The 17-50mm's extra reach should make it a good choice for photographers who crave additional compression and background separation the 50mm angle provides. Because of the 50mm reach, the lens can do double duty as an everyday zoom for many photographers.

Tamron promises a decent, but not spectacular, close-up distance. The lens focuses to 7.5 inches at 17mm and 11.8 inches at 50mm, both measured from the front element, not the sensor, which is the more common measurement for close focus. It has not yet published a maximum magnification rating for macro work, but given those figures we expect it to be just-okay for close-ups. Other features include a linear autofocus motor, along with a weather-sealed design for outdoor use.

Tamron is billing the 17-50mm as the first lens of its kind, and it's true we've not seen any other full-frame options with the same range. The closest alternative is the Sony FE 20-70mm F4 G, and while only 3mm separates them in focal length, there's a notable difference in angle of view. Photographers who lament that the FE 20-70mm isn't wide enough will want to weigh the 17-50mm as an alternative when it comes to market.

The 17-50mm F4 Di III VXD is expected to go on sale this autumn. The exact timing and price are still to come.
