The Micro Four Thirds system is an open standard for mirrorless interchangeable lens digital cameras and digital recorders that was created by Olympus and Panasonic back in 2008. Pick-up on the technology has been gradual, to say the least, but it looks like the system is starting to gain momentum.
Late last year, Olympus announced that they would be releasing their first electronic zoom Micro Four Thirds lenses. Sigma and Panasonic also unveiled their own lenses and systems following the MFT standard.
Now Tamron, Tokina, and Astrodesign have announced that they are joining the Micro Four Thirds group to produce lenses adhering to the MFT system.
Tamron is a company that was established in 1950 that specializes in interchangeable SLR camera lenses and lens units for surveillance. Tokina is a firm that designs and produces a variety of photographic supplies and optical products. Lastly, Astrodesign is a company that develops professional video equipment and measurement/analysis-related gear. All are based in Japan.
Aside from announcing their decisions to join the MFT group, the firms have yet to reveal their plans for future products.
