The E-P1 will be supplemented by more distinct Micro Four Thirds models and with more professional features, Olympus product planning manager Akira Watanabe said in the wake of the new camera launch today. He explains to DPReview that the E-P1 is just the first in a larger range and that at least one future model will have an electronic viewfinder, much as Panasonic's Lumix G1 and GH1 have now.
