## Overview

The Fotodiox Pro B4 Magic Adapter is a premium brass lens adapter designed to mount 2/3" B4 ENG zoom lenses onto Blackmagic Micro Four Thirds cinema cameras. It features built-in optics that correct image alignment and prevent vignetting, supports typical 15x and 20x zoom lenses, and includes an integrated Arca-Swiss tripod foot and a custom metal lens cap. This adapter offers filmmakers affordable access to professional powered zoom lenses, enhancing creative flexibility and camera placement options.

## Description

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.Compatible Cameras:Blackmagic Pocket Cinema Camera (MFT)Blackmagic Micro Cinema Camera (MFT)Blackmagic Micro Studio Camera 4K (MFT)Blackmagic Studio Camera HD (MFT)Blackmagic Studio Camera 4K (MFT)Note:Lens Technical Requirements: B4 mount designed for 2/3" sensor - look for better grade lens that resolves to HD resolutions. Impossible to list them all here. Even in the SD era, there are lenses that resolve to HD quality. A little research will uncover numerous lens bargains on the secondary market. You can easily find B4 lenses on eBay, B&H, Craigslist and practically anywhere that sells used video production gear, with prices commonly starting as low as $100.The B4 Magic Lens Adapter is designed to work with lenses set to f5.6 and greater, (most B4 lenses are optimized for best focus at f5.6 and greater). Please be aware that shooting below f/5.6 may result in soft focus depending on your lens.All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.

Review: Excellent - Good good good
Review: Has a bit of play. - I like that I got the adapter to work with the blackmagic mini studio camera. It is well built but, it does not fit snug. It has a bit of play to it . Unfortunately with the play there is some vignetting. But, if the lens is raised a bit the vignette diminishes a bit.

## Features

- Offers the creative flexibility of a powered zoom lens for a fraction of the price of similar options
- Premium quality brass construction with a smooth surface for effortless mounting
- Take advantage of the typical 15x and 20x zoom lengths to be even more flexible with camera placement
