The Olympus 45 1.8 Micro 4/3 Lens Review by Steve Huff. Okay, with Steve you always have to subtract some enthusiasm, but the 45/1.8 really sounds very exciting. The Micro 4/3 system is finally gaining momentum. Some of the latest lenses that have been announced and actually released are very interesting. The same goes for the Olympus 12/2.0 or the Panasonic 14-42 Powered Zoom (yes, yes, powered zoom sounds like a compact camera, but hey, the lens is extremely small and thus ideal for the GF1 for an always-with-you camera with a bit more flexibility than the 20mm). I'm still torn between the Sony E-Mount and the Micro 4/3 system, but in the end, it will come down to the lenses - what good is a system that is better in terms of the sensor if the lens selection is too limited. Sony is definitely releasing new bodies too quickly - and too slowly new lenses.
