I bought mine as an alternative to the Sigma 16/1.4 (a very good lens and a great value) for high quality video, specifically webinars and live calls. It has a tighter field of view and because of the increased focal length slightly more background blur and less facial distortion at 3'/1M away. It's very sharp and focuses very well on my Olympus OM-D E-M1 Mark Ii and II bodies. I think it's the perfect Zoom/webinar lens. It's also a great casual photography lens. Highly recommended. My only wish is that it had true manual focus like the 12-40/2.8 Pro.
