#Disassembling om system lens full#

In this guide Juriaan, Phillip and I will take you through the lenses with comments about how they perform, and whether they make sense adapted to Sony full frame digital cameras. I was an OM system user back in the days of film, so you’ll see a few samples from me that are from OM film cameras, as well as digital. This makes them very tempting options for someone who wants to explore them on a modern full frame camera, or for someone who wants to experiment with film. They are all nicely engineered and a joy to use. To help determine the amount of light that enters a Micro Four Thirds-mount camera when using this adapter and a Contax/Yashica-mount lens, users should use the aperture ring found on the lens.Yoshihisa Maitani’s Olympus OM system was a remarkable achievement, with beautifully engineered smaller bodies and exquisite small lenses, often as good or better than larger lenses from the competition. The Speed Booster Ultra 0.71x Adapter for Olympus OM-Mount Lens to Micro Four Thirds-Mount Camera does not support electronic communication between an attached camera and lens. Inside are five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and a detachable tripod foot is included that features 1/4'-20 threads as well as compatibility with Arca-Swiss tripod heads. This adapter is constructed from aluminum alloy for durability while minimizing weight and its mounting rings are made with brass to further prevent wear-and-tear. This allows a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional 1 stop of light for each of the lens's f/stop settings.

Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera 'crop factor.' The Speed Booster Ultra 0.71x Adapter for Olympus OM-Mount Lens to Micro Four Thirds-Mount Camera condenses the light from a lens designed for 35mm film or 'full frame' camera sensors and projects it onto a Micro Four Thirds sensor.

If a lens intended for 35mm film or similarly-sized full-frame camera sensors is connected to a camera with a Micro Four Thirds-sized sensor, it would project an image larger than the Micro Four Thirds sensor was built to accept. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1-stop increase for the camera over the lens's aperture range.

The Speed Booster Ultra 0.71x Adapter for Olympus OM-Mount Lens to Micro Four Thirds-Mount Camera from Metabones allows a Olympus OM-mount lens to be mounted onto a Micro Four Thirds-mount camera.
