Wide angle adaptor rings 49mm
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.
