Transform your Canon EF-mount Laowa 12mm f/2.8 Zero-D lens into a 17mm f/4 lens with ±10 mm of shift for full-frame Sony E-mount cameras by using the Laowa Magic Shift Converter from Venus Optics. This converter works by using optics, including two Extra Refractive elements, to magnify the image circle to 60mm, providing space to make adjustments while remaining free of any vignetting. It can also rotate 360°, making it easy to switch from portrait to landscape orientation when required. When used, this setup will help users create images with straight vertical lines, which is especially useful for architectural and interior photography. Additionally it has a metal construction for durability.
