range of AT-X PRO lenses from Tokina is set to increase with the launch of a new
AT-X 28-70mm PRO SV f2.8 lens.
By using new manufacturing technology and
materials, Tokina say they have not only improved the barrel design for more comfortable
handling but also reduced the overall weight of the lens, which has resulted in
a lower cost AT-X lens to the end user.
The 28-70mm features a constant
f2.8 aperture throughout the zoom range, which is excellent for low light photography
at any focal length, while the wide aperture allows more light through for picture
taking in difficult lighting situations.
The lens can easily be switched
from auto focus to manual modes. While in manual focus, the lens has a damped
action for smooth precise focus movement. Use of filters is convenient thanks
to the non-rotating 77mm filter thread on the front lens barrel.
