Shooters committed to the Four Thirds System, take note. Here is Serious Glass. This pro-caliber 70-200mm equivalent zoom ($2,200, street) — the world’s fastest in its focal-length range — packs four elements of ED glass, one element of Super ED glass, and all-metal construction with rubber seals to keep out moisture and dust.
Conclusions:
It’s heavy and — ouch! — expensive, but it
promises optical performance that, in many circumstances (low light
with moving subjects, for example), could give a pro a significant
competitive edge.
