About Metabones

The Metabones Olympus OM Lens to Micro Four Thirds Mount Camera Speed Booster allows a full frame Olympus OM lens to be mounted to a Micro Four Thirds mount camera and in doing so, increases the angle of view and increases the maximum aperture one f/stop.

When a lens intended for full frame sensors or 35mm film is mounted to a camera with an Micro Four Thirds sized sensor, it transmits a larger area of light than the smaller sensor was built to accept and therefore the angle of view of the lens decreases and the equivalent focal length increases. The Speed Booster condenses light from the lens and projects it onto the smaller sensor allowing the sensor to utilize all of the lens' light and effectively produce a full-frame angle of view with an MFT sensor. A corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field.

Metabones Speed Boosters are quality made, using precision-machined brass with chromium plating on both the camera-body and the lens sides of the booster in order to ensure smooth mounting, quality aesthetic and durability. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins and Photo Clam ball heads.

Faster Speeds, Wider Angles


from San Jose, CA

This is a great accessory for Micro 4/3! This adapter widens the 35mm OM lenses by .7x, meaning a 50mm OM lens will equate to a 35mm m4/3 lens (Verified). The extra light gathering also increases the speed of the lens, and narrows the depth of field: claimed to be a full f-stop, but have not tested the exact figures. becomes a toss up between regular adapters for telephoto work due to the crop, but if you need the extra speed its good. Easy way to double the versatility of your OM lenses.
