Kenko-Tokina exhibits mockup of image-stabilised 70-200mm F4 at CP+

Kenko-Tokina exhibits mockup of image-stabilised 70-200mm F4 at CP+ | Photography Gear News | Scoop.it

"Kenko-Tokina is exhibiting a mockup of a 70-200mm F4 telephoto zoom that features both a ring-type ultrasonic autofocus motor and optical image stabilization at the CP+ trade show in Japan. The AT-X Pro SD 70-200 F4 (IF) FX will be the company's first stabilized lens, and will likely be especially interesting to Nikon SLR users who currently have no option that's directly comparable to Canon's popular and highly-regarded 70-200mm F4 designs. Further details are limited, but the lens appears to feature both internal zoom and focus mechanisms, and has a usefully-close minimum focus distance of 1m."

Kenko-Tokina Reflex 300mm F6.3 compact telephoto for Micro Four Thirds

Kenko-Tokina Reflex 300mm F6.3 compact telephoto for Micro Four Thirds | Photography Gear News | Scoop.it

"enko-Tokina has added the mirrors back into mirrorless with the launch of an ultra-compact Reflex 300mm F6.3 for Micro Four Thirds. This fixed-aperture, manual focus lens revives the catadioptric lens design that was especially popular in the 1970s and '80s for producing small high-magnification telephoto lenses. With a 55mm filter diameter and weight less than 300g, this is possibly the smallest lens of this type that's ever been made for stills cameras. The spec is rounded-off with a minimum focus of 0.8m and 0.5x maximum magnification, making the lens potentially interesting for chasing insects and the like, just as long as you can hold it steadily enough.

The catadioptric design allows long effective focal lengths in small packages but does give characteristic 'doughnut bokeh' patten of sharp-edged rings in defocused areas."
