The Lee Seven5 Starter Kit contains a 0.6 Neutral Density Hard Grad Filter and a Lee Seven5 Filter Holder. The filter features a hard graduation from dark to light and is designed to reduce exposure by 2 stops without affecting colour balance. ND Grads enable you to balance light intensity in one part of a scene with another. For example, when photographing a landscape in which the sky is much brighter than the foreground, placing the neutral density part of the filter onto the sky in the frame will reduce the sky exposure without affecting the foreground. Adapter ring not included.
The filter slots into the Seven5 filter holder (included) and attaches onto the end of your lens using an adapter ring (not included, available separately). Please check your lens for the thread size. Adapter rings are available in the following thread sizes: 37, 37.5, 39, 40, 40.5, 43, 46, 49, 52, 55, 58, 60, 62, 67 and 72mm.
