It's hard to be motivated to write about this lens. It's large, overpriced for what it is, and not even designed for Micro Four Thirds.
Still, we should probably be grateful to have a 1200mm equivalent lens with IS in a native m43 mount.
The $2700 price is too much. The size and weight is arguable too much for a m43 lens.
