In the DSLR filmmaking world, it's always been challenging and expensive to attach a powered zoom lens onto your camera. Recently a few manufacturers have offered motorized zoom lenses at prices of $10-20,000 – a premium price that keeps these versatile lenses out of reach for most digital filmmakers. DSLR zoom still photography lenses are less than idea for dramatic zoom shots because they are rarely “parfocal” i.e. the aperture changes over the duration of the zoom, which spoils the shot.

Older ENG (Electronic News Gathering) lenses are a breed of powered zoom lenses that have many of the features that a modern digital filmmaker needs. Affordable ENG lenses are easy to find, and can create great HD video, but making them work with today's digital cameras has been an expensive and difficult challenge. Until now...

The B4 Magic Lens Adapter is an all brass adapter with built-in optics to correct your B4 lens' image to align with the Black Magic Pocket Cinema Camera's sensor. There is no vignetting, even when the lens is zoomed out all the way. The B4 Magic Lens Adapter features a built in tripod foot with an integrated Arca-Swiss quick-release compatible base. Like other teleconverters, the optics built into the B4 Magic Lens Adapter will reduce the light hitting your sensor up to 1-stop.

The adapter also comes with a B4 Magic Lens Adapter Cap; this custom all-metal cap fits on the front of the B4 Magic Lens Adapter. B4 body caps are exceedingly rare, so we created one to keep the optics of the B4 Magic Lens Adapter safe when you remove your B4 lens.
