Olympus 8mm f1.8 Fisheye review at CameraLabs.

Gordon from CameraLabs (Click here) posted the full Olympus 8mm PRO lens review:

Ultimately the Olympus 8mm f1.8 Fisheye may be larger and higher-priced than rivals, but it’ll out-perform them on the feature-front, particularly in terms of aperture. If you’ll exploit these features, it’s well worth spending the extra and comes highly recommended. I also commend Olympus on pushing the envelope here and producing a lens that’s truly different from anything that’s come before for any format. It’ll be a reason for some photographers to select Micro Four Thirds as their next format.
