This news falls into the category “very unlikely rumors“. CanonRumors reports that Canon may announce a new 55mm f/1.3 lens in March which he speculates to be an EOS-M mount lens. The only thing I heard (and I reported it yesterday) is that new EOS-M mount lenses will be announced in Spring 2013. But i haven’t heard about a 55mm lens yet. Anyway, would be a welcome addition to the EOS-M range! Something similar is going to be announced by Panasonic, to be more precise it is the 42,5mm f/1.2 lens. This one is not a rumor. Panasonic said it will release it in 2013.
