Magnifies focal length to 0.7x, can convert camera lenses to focal length near 1.4x to those in 4/3 format cameras. (e.g. 50mm x 2 x 0.7 = 70mm).
Increase exposure to 1 stop, and you can use faster shutter speed to shoot an image.
Works fine, closely combined with the bayonet smooth, like the original lens.
With unique styling, the lens mount adapter maintains/ enhances professional appearance.
