This is a special LEE100 System adaptor ring for Olympus 7-14mm Pro f2.8 ultra-wide zoom lens.

This ring has been specifically designed to fit this popular lens. The adaptor consists of a front ring, a compressor ring and a locking ring that form a collar which remains on the lens at all times.

Please note: due to the extremely wide angle view of this lens we recommend using a minimum focal length of 10mm to avoid vignetting.
