Kenko Tokina has re-announced its lightweight 300mm mirror lens for Micro Four Thirds. Now named the “Tokina Reflex 300mm f/6.3 Macro,” the lens measures only 66x66mm (length x diameter) and weighs in at a mere 300 grams - remarkable figures for a lens whose angle of view is similar to that of a 600mm optic in a 35mm system. Like the vast majority of mirror lenses, the Tokina Reflex 300mm f/6.3 Macro is a manual-focus lens with a fixed aperture. The lens takes 55mm filters, focuses down to 0.8m and offers a maximum reproduction ratio of 1:2 (hence the “macro” designation), In Japan, the Tokina Reflex 300mm f/6.3 Macro is scheduled to go on sale next month for 40,000 yen excluding taxes.
