Press Release
Kenko Co., Ltd. is pleased to announce that the launch and for for Canon Nikon “AT-X 14-20 F2 PRO DX” as an interchangeable lens for APS-C digital single-lens reflex camera.
Large-aperture wide-angle zoom lens of Tokina’s first open F value F2.0
When you set the ISO sensitivity low, the handheld shooting can be set to enough shutter speed. Also, shooting was taking advantage of the blur, in night photography, etc. open F value of 2.0 and delivers the preeminent power.
High precision plastic aspherical lens
essential to a wide-angle two-group zoom lens, the plastic aspherical lens further pursue the G02 of surface accuracy, it is in a strong design to ghost flare. Also, so as to obtain a clear imaging to peripheral angle of view of a wide-angle, we conducted the optimization of the anti-reflection coat.
Placement of high precision ultra-low dispersion glass mold aspherical lens
in the rear lens group, with ultra-low dispersion glass mold aspherical lens is placed two pieces of, various types of aberration correction result that is properly subjected to, open F value of 2.0 bright lens , we have realized the high resolution and low distortion throughout the zoom range.
Compact body and good operability
by a one-touch focus clutch, feeling at the time of manual focus, there is a moderate torque sense of focus ring, allowing precise focusing.
In APS-C size (DX format) of ultra-wide-angle zoom lens, provide an open F value of 2.0, also will deliver preeminent power in the moving image shooting.
Filter size C-PL filter in 82mm is also available.
Lens constitution
The power of the next generation “large-diameter F2.0 wide-angle zoom”
Tokina we have developed and released ahead of the F2.8 large-aperture ultra-wide-angle zoom to other companies. As future large aperture wide-angle zoom, achieving an open F value 2.0, it was also the challenge of Tokina planning and development. For the request of a large diameter single-focus lens from customers, the results of the examination answers as Tokina, while a zoom, AT-X was setting the optical specification that enables the equivalent imaging performance and single-focus lens 14 We started the development of -20 F2 PRO DX. As a new attempt to achieve an open F value of 2.0, sets the zoom range to the high frequency of use 14-20mm. This is, we finished the descriptive power that is comparable on the basis of the concept of “Choi and plus be a single-focus lens”, the AT-X 14-20 F2 PRO DX optical performance of a single-focus lens. This is a single-focus lens 14mm that already exists, 16mm, 18mm, 20mm (21mm in 35mm format, 24mm, 27mm, 30mm) covers the 4 duty of, and yet, exert enough imaging performance from the open F2.0 In order to, we are incorporating the optical design concept of the new development. If you set low ISO sensitivity, you can set the handheld shooting in fully possible shutter speed. Also, shooting was taking advantage of the blur, the open F value of 2.0 in nighttime shooting is quite useful.
Tokina has defeated the traditional concept, the large aperture wide-angle zoom unparalleled. Please enjoy the descriptive power.
