Image on top: the Four Thirds Zuiko 14-35mm f/2.0. Same quality can be expected by the new f/2.8 zooms.
I am getting more and more evidence that Olympus will release a fast zoom in Spring-Summer along the new E-P5. And I now have been told that Olympus actually wants to release two f/2.8 zoom within 2013. Both will compete against the Panasonic 12-35mm and 35-100mm X lenses.
Which one is coming first I don’t know yet. I asked the sources if that wouldn’t be too redundant but they told me that Olympus zooms deliver a higher optical performance as we have on the superb Zuiko 14-35mm f/2.0 (here on eBay) and Zuiko 35-100mm f/2.0 (here on eBay) lens. Specs and Price info are yet unknown. What we can be (almost) sure of is that the constant aperture isn’t f/2.0, it will be almost certainly f/2.8 becuase of size and costs reasons.
