This video was filmed using a set of cinematic macro lenses I designed for Lindsey Optics in 2017.
Cinemascope lenses are used in filmmaking to achieve a widescreen aspect ratio. Anamorphic lenses are used to compress and later expand the image horizontally during projection, providing the wider field of view.
Although I can’t show the designs I created for my client, I can share a reference design from Hallock Smith that I used as a starting point. This design form works best with longer EFL camera lenses and very long working distances. It needs dynamic astigmatism correction (not shown) to work well over a wider variety of use cases. Another approach is to locate the anamorphic pair between the camera body and lens.
