After reading threads about variable ND filter in this forum and watching numerous you tube video, I have decided to buy a Tiffen variable ND. But i need some advise on the size of the filter. Right now my lenses are either 62mm and 52mm filter size, should I buy a 62mm or should I buy a bigger size like 77mm to future proof? The price different is very big.
As I have no experience in buying filter, any advise is much appreciated. Thank you.
