Metabones Speed Booster ULTRA 0.71x – Canon EF to Micro Four Thirds (MFT) The Metabones Speed Booster Ultra is the gold standard for Canon EF lens adapters on MFT cameras like the Panasonic GH4, GH5, or Blackmagic Pocket. The 0.71x focal reducer compresses the image circle, giving you a wider field of view and gaining one full stop of light — effectively turning an f/2.8 lens into an f/2.0. What it does: • Mounts any Canon EF lens on Micro Four Thirds bodies • 0.71x crop reduction — closer to full frame feel • +1 stop light gain • Retains full electronic communication (AF, aperture control, EXIF) Condition: Very Good. Minimal signs of use as seen on the pictures. Optics clean. Electronics fully functional. What’s included: • Metabones EF–MFT Speed Booster Ultra 0.71x adapter • Original box and container This adapter pairs well with the Panasonic GH4 and canon lens, which are also for sale. Shipping & Pickup: Can be shipped or picked up in person in Hasselt, Belgium.
