A new Micro-4/3 mount Speed Booster adapter designed exclusively for the Panasonic GH4 and other selected Micro Four Thirds cameras, with a magnification of 0.64x. The Speed Booster XL 0.64x uses an advanced 6-element optical design to achieve extraordinary optical performance at apertures up to an incredible f/0.80, a new record for Micro Four Thirds format.The new Speed Booster XL 0.64x reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x, thus effectively transforming these cameras into APS-H format. When the GH4 is used in Cinema 4k video mode the horizontal full frame crop factor is reduced from 2.34x to 1.50x, thus effectively transforming the GH4 into a super-35 format 4k cine camera. In addition, the speed of any attached lens is increased by 1 1/3 stops, with a maximum output aperture of f/0.80 when an f/1.2 lens is used. For example, a 50mm f/1.2 becomes a 32mm f/0.80, which is the fastest aperture available for full size Micro Four Thirds format. Optical Increase maximum aperture by 11/3 stop Increase MTF Makes lens 0.64x wider Patented 6-element/4-group optical design by Caldwell Photographic in the USA Supports 4k video mode with DX lenses (except on GH5).

This Lens Mount Adapter from Viltrox allows a F-Mount, D or G-Type lens to be mounted onto a Micro Four Thirds camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range. If a lens intended for larger camera sensors is connected to a Micro Four Thirds camera, it would project an image larger than the camera's sensor was built to accept. 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. This adapter condenses the light from an attached lens and projects it onto a Micro Four Thirds camera's sensor. This allows the camera 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 one stop of light for each of the lens's f/stop settings. This adapter supports manual focusing and eight stops of aperture control. It is constructed with five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and the underside of its removeable tripod foot is tapped with a 1/4-20 accessory thread, enabling direct attachment to a tripod or quick release plate that feature 1/4-20 mounts.
