This has to be the most exciting news this year so far, and I’m not certain if it can be surpassed by anything else! Last night, it was rumored on 43rumors.com that an exciting Micro Four Thirds announcement would be made soon, and that it wouldn’t be any of the major players. Later is was also mentioned that it would be a rangefinder company, leaving only a hand full of possibilities. Today the bomb exploded, and now it’s official: Cosina not only announced to join the Micro Four Thirds consortium, they also announced production of a dedicated 25mm f/0.95 Micro Four Thirds lens – although completely manual, as with all Cosina made lenses.

The news is all over the web already, so here’s a collection of links leading to the most important information.

EDIT: According to this translation of Cosina’s original Japanese announcement, they’re going to produce even more Micro Four Thirds products (not necessarily only lenses!) in the future. Thanks to the OP on dpreview forums.
