    Cons: A bit tiring when shooting video hand-held.

    Pros: Excellent contrast and sharpness at f/1.4 from centre to corner. Good bokeh at the background. Almost no chromatic aberration. Quiet and accurate autofocus. Do not cost you a fortune.

    Summary: Stable, reliable and it works well on my Sony α7R3. Probably one of the best Sigma lenses you can buy now.
