The Laowa Probe Zoom improves upon their previous fixed focal length probes. This probe gives you the ability to shoot with a much wider FOV, which is very helpful especially when using this on S35 sensors. The lens also gives you the ability to zoom which can be used for some creative in camera effects as well as allowing you to reframe quickly. This lens features all of this while maintaining a T8 aperture. The Probe Zoom is the go to lens for most macro cinematography.
