Dear Valued Customer,
We hope that you are enjoying a healthy and prosperous year so far. We thank you very much for the patronage you have entrusted to us. At this time Kenko Tokina Co., Ltd. (President and CEO Toru Yamanaka) is pleased to announce the release of the AT-X 12-28 PRO DX (12-28mm F/4). This lens is the successor to the popular AT-X 124 PRO DX II.
Wide-angle to semi-standard zoom lens
As the successor of the AT-X 124 PRO DX II (12-24mm F/4), which has been loved by photo enthusiasts the world over for many years, the AT-X 12-28 has an increased telephoto focal length from 24 to 28mm for greater use and versatility. We have provided a new optical design to match even the 20 mega-pixel DX sensors. In addition, we also improved factors such as color balance and blur quality, also known as Boken. This lens is designed to match the power of high-megapixel sensors in a conventional wide-angle to semi-standard zoom.
Achieves higher image definition through the use of glass-moulded aspherical lens elements and inclusion of ultra-low dispersion glass.
An aspherical P-MO lens element is positioned in the front group. This, together with a moulded glass aspherical lens placed in the rear group, ideally corrects for aberrations while also correcting distortion. The use of SD glass (ultra-low dispersion glass) FK01 and FK03, which emulate fluorite glass in performance, aims to eliminate chromatic aberration.
New auto focus mechanism
The new AF control sensor in the lens is a “GMR (magnetic precision) sensor” capable of high-resolution auto focus is mounted close to the drive unit for better efficiency. Fast AF speed is achieved through the high-precision focus control. Furthemore, adoption of a newly developed “SD-M” (Silent Drive-Module) has greatly lowered the sounds emitted by the AF drive. The Nikon mount version has an auto focus motor built-in.
Compact body design with good handing
The size of the lens is the same as the AT-X 124 PRO DX II maintaining its very compact design. Through the use of a one-touch focus clutch AF/MF mechanism, just slide the manual focus ring forward for AF or rearward for MF operation. The lens has a good manual focus feeling as though the MF operation were damped for precise operation.
