M.ZUIKO DIGITAL ED 100-400mm F5.0-6.3 IS. This is the initial model. I'm currently using it as my main lens for bird photography, but I'm selling it because I'm considering upgrading. There are cracks in the lens hood and exterior. The other parts are in good condition, and I've been using it for over a year and a half. However, it is a used item, so please consider purchasing it as-is. - Brand: OLYMPUS - Model: M.ZUIKO DIGITAL 100-400mm f/5.0-6.3 - Accessories: Lens hood, rear cap - Condition: Cracks in the hood and exterior, otherwise in good condition.
