From Kenko:

Kenko is proud to announce details and availabiliy of their TELEPLUS HD pro series of teleconverters.

The TELEPLUS HD pro series replaces the previous TELEPLUS PRO300 series, with redesigned optics and multi-layer coatings, to match contemporary high-resolution DSLR cameras and lenses. The HD pro series joins the existing, new-generation TELEPLUS HD line up (1.4x and 2x types) as a superior series in terms of optical design and coating quality.

* available in Nikon F and Canon EF mounts

Optical Improvements

Optical construction has been redesigned by implementing additional optical elements and improved multi- layer, anti-reflection coatings to maintain the original performance of new-generation DSLR cameras and lenses.

Communication with the Camera

HD pro teleconverters are equipped with all electrical contacts to support communication between the camera and the lens. The focal length and aperture values are recorded in EXIF data and converted to the actual shooting values with the teleconverter attached.

High-end External Finish

The external design has been re-finished in a black leather tone to perfectly match with the latest lenses and DSLR cameras.

Compact Size

With approx. 0.79" (2 cm) in height for the 1.4x type and 1.57" (4 cm) for the 2x type these small, compact and convenient to carry tele converters will extend the focal length of the lens providing the photographer a great chance to shoot even more impressive images.

Kenko's new TELEPLUS HD Pro Teleconverters are available now at Kenko-Tokina authorized retailers.

B&H has the Kenko TELEPLUS HD pro DGX Teleconverters in stock with free expedited shipping.
