Product Code: VB-DORR-VARIABLENDFILTERS
This Dorr Variable Neutral Density 77mm 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.

40.5mm & 46mm = Two stepping rings with be provided, allowing the filter to fit a 40.5mm thread and a 46mm thread.
