Standard adaptor rings
The adaptor rings in our standard range are compatible with lenses of a moderate wide angle — approximately 24-28mm full-frame equivalent — and longer. They are available in the following thread sizes: 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, 86mm, 93mm, 95mm, and 105mm.
 
To avoid vignetting, we recommend using our wide angle adaptor rings when shooting with lenses wider than approximately 24mm. The crucial difference between these and the standard rings is that they sit closer to the front element of the lens. Wide angle adaptor rings are available in the following thread sizes: 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, and 82mm.
 
The wide angle adaptor ring from LEE is crucial to the LEE Filters system, allowing you to attach the LEE100 filter holder to your wide-angle lens.
The adapter ring screws on with a fluid action, thanks to the sturdy construction and aluminium screw thread.
All the LEE100 wide-angle adaptor rings are suitable for use with wide-angle lenses. They differ from the standard adaptor rings by sitting closer to the front element of the camera’s lens, dramatically reducing the likelihood of vignetting on lenses with a focal length of 16mm or more (10mm with a crop sensor)

Please check the thread size on the front of your lens before purchasing
