My previous experiences with it: Top processed faster and quieter autofocus (which provides really quickly sharp and always on the spot). The lens has met my expectations fully. The imaging properties I have now not meticulously tested, when I look at my photos so, then satisfies the demands my full (mostly presentation on HD television with 55 "screen size).
Not so impressed I was of the packaging: The Objketiv was delivered in a simple cardboard box. I would have at least expected a lens-quiver. But is currently not so important, as I currently classified as "always on it" use lens. But could change times when more are added.
