VERDICT

Panasonic engineers have done it again! They have produced another superb lens which will be a boon to nature and wildlife photographers. Yes, the lens is ‘slow’ but this is a compromise we have to accept in lieu of the small size and low weight. And again, with the right Micro Four Thirds body like the Panasonic GH4, one can get excellent image quality in spite of the comparatively smaller sensor. Best Buy indeed!
