I am looking to buy one. Is there a difference though between a 0.6 and a 0.9 filter? If there is can you tell me what it is?
Ok thanks everyone. Westside Guy... I was really talking about any specific brand but more just generally what does it mean.
There may be some rationale in the numbering system that I've just somehow managed to miss; but my impression has been that what label translates to what degree of light blockage depends on the brand. So... what brand are we talking about?
