Build Quality
This is not a lens for everybody; it´s big and heavy as a standard lens and because of the long focus throw it is slow to focus and therefore not made for action, but video and macro photographers will love it. Zeiss has paid a lot of attention to detail and all text and numbers on the lens barrel are engraved like in the good old days and I really like that instead of modern lenses where everything is printed and might peel off after years of intensive use. The Zeiss lenses does not have weather sealing, but the lens is not as fragile as modern lenses equipped with Image Stabilization and an autofocus motor, so I think the Zeiss lenses are very durable in the long run; I have used my Zeiss lenses in the rain, blizzards and sandstorms without any mechanical problems!
