Do all variable ND filters have a starting point of ND 2?

 

Three variable ND filters that I have recently purchased have some amount of darkness, even at the lowest possible setting.

 

It makes sense to me to have a filter that has a starting point of nothing... then have the option of going to ND 2 or more if needed.

 

To begin with ND 2 isn't going to work.

 

Am I making a mistake in purchasing moderately priced filters? Is what I am seeking even offered?

 

Could anyone advise me, I admit to being a hobbyist.

variable nd's are made by stacking two polarizers together so they always take some amount light even at "open" setting. a nd wheel similar to camera's internal nd wheels (couple of regular nd's + clear) or a graduated nd wheel would be the only option if you would like to minimize the light loss at "open" position, no polarizer based option would work
