This Dorr Variable Neutral Density 37mm Filter allows you to adjust the amount of light reaching the camera lens by as much as 8 exposure stops – without affecting the colour. The slim profile helps avoid vignetting and the matt finish means no annoying reflections which can spoil a good photo.
Each filter size, (except the 37mm size), comes with one or two stepping rings that can be used to attach the filter to different sized filter thread. For example:
49mm | 40.5mm & 46mm Variable
49mm = The thread size the filter will fit WITHOUT using a stepping ring.
40.5mm & 46mm = Two stepping rings with be provided, allowing the filter to fit a 40.5mm thread and a 46mm thread.
