Metabones Nikon G To Micro 4/3 Speed Booster XL Adapter

The Metabones Nikon G to Micro 4/3 Speed Booster XL Adapter allows you to mount any Nikon F-mount lens to compatible Panasonic Micro 4/3 cameras. Key features include:

• Optimized for Panasonic GH4

• Wider focal length and increased aperture

• Eight-stop aperture ring

• Sturdy design with built-in tripod foot

Optimized for Panasonic GH4. The Speed Booster XL is targeted at , , and users. What sets it apart from the standard Nikon G to Micro 4/3 Speed Booster is its 0.64x focal-length reduction. This effectively reduces the sensor crop factor to 1.28x in still-image capture, and more importantly, 1.5x (Super 35) in 4K video capture.

Lens Compatibility. The adapter works with both G and non-G series Nikon F-mount lenses, including legacy non-AI and AI lens mounts. This allows you to use a much larger lens base. Due to the smaller Micro 4/3 sensor, you can also use DX (crop-frame) lenses.

Camera Compatibility. The Speed Booster XL isn’t compatible with all Micro 4/3 cameras. According to Metabones, the only compatible cameras are the Panasonic , , , GH3, G3, G5, G6, G10, GF3, GF5, GF6, GX1, Olympus E-PL7, BMCC Micro 4/3 Mount, and the BMPCC. If you mount this adapter to any other camera, you could damage the camera’s shutter!

Wider Focal Length and Increased Aperture. This version of the Speed Booster widens the mounted lens’s focal length by 0.64×. Additionally, the adapter increases the mounted lens’s maximum aperture by 1.3 stops to a maximum of f/0.8 when using an f/1.2 lens.

Aperture Ring. The adapter has its own eight-stop aperture ring for controlling Nikon G-series lenses without their own aperture rings.

Sturdy Design with Built-In Tripod Foot. The aluminum barrel and brass mounts give it a solid feel, with an Arca-Swiss compatible tripod foot that lets you mount the adapter itself directly to a tripod. This ensures the lens’s weight doesn’t put additional stress on the camera’s mount.

What This Adapter Doesn’t Do. This adapter provides no electronic communication with the camera, so you won’t have autofocus, and EXIF data will not be transferred. You can’t set the camera to auto and start shooting; you must make some manual exposure adjustments first.
