Hands-On Review: Metabones EF-E Mount Adapter IV & EF-BMPCC Speedbooster

In the following video, Mia McCormick, from KelbyOne, discusses a new adapter and Speedbooster from Metabones. The Metabones Canon EF Lens to Sony NEX Camera Lens Mount Adapter Mark IV attaches a Canon EF lens to APS-C and full frame Sony E-mount cameras. The video explores its improved internal structure, its electronic communication with camera and lens, and the pros and cons of focusing with the adapter. McCormick also demonstrates the Metabones Canon EF Lens to Blackmagic Pocket Cinema Camera Speed Booster, which will not only attach a Canon EF lens to a Micro Four Thirds-mount Blackmagic camera, but enables an increased maximum aperture of 1-2/3 stops and a 0.58x wider angle of view.
