43 Rumors | Blog | (FT5) The new lens specs: 12-50mm f/3.5-6.3 and macro! Wow, this is certainly very disappointing if the rumored specs are correct. Not only is it 12-50mm as opposed to the 12-60mm, it's also f3.5-6.3 instead of the f2.8-4.0 or f2.8-3.5. Why the hell do we need another slow zoom lens for the micro 4/3 system?!? Thank goodness I bought the Olympus 4/3 Zuiko 14-54mm f2.8-f3.5 mkII lens on Thanksgiving. I would have lost out on shooting with for the last several weeks if I had waited around for this new lens. If this is in fact true, this is just as bad as when Nikon announced that its mirrorless camera will have a smaller sensor than the micro 43 sensor.
