Congratulations to SIRUI! Its 50mm F1.8 Anamorphic lens is Videomaker’s pick for the best lens of NAB Week 2020. It was a highly anticipated lens in the community, with the announcement video racking up almost 900K views on YouTube. The lens surely delivered on all of its promise.

This lens features a 1.33x squeeze factor and can shoot 4K high-definition cinematic 2.4:1 video. Additionally, it will come with a 33% increase of the horizontal field of view. This will allow the lens’ field of view to match an APS-C 37.5 mm lens. It’s also a great lens for making your shots look a lot more cinematic. For these reasons and more, it’s our pick as the best lens of NAB Week 2020.
