The Letus Micro 4/3 to PL Mount, designed to work with the Pro Camera Base, overcomes the task of setting your lens back focus via shims and serves as a simple, back focus adjustment ring. All you have to do is rotate the precision machined ring and lock it down at your desired back focus point.
Thanks to this mount, you can now attach an Angenieux zoom lens to your Panasonic AF100, GH1, or GH2. While the mount flange is carved out of high grade stainless steel, the internal housing is matte coated to eliminate internal barrel glare.
