EF to M4/3 adapter. Many folk on the net have remarked that this adapter with aperture wont work. Often saying \'\' you cannot defy the laws of physics\'\' . I guess I defied the laws of physics as many others do.
Truth is, the problem with this adapter, is with the ef lenses which have a recessed rear lens, it will vignette quickly when stopping down. The Macro ef100 f2.8 and ef400mm f5.6 being typical of this type of lens. But I do use it on both happily with these restraints.Lenses like the 50mm and 85 it works well.
