I have listed these 2 filters.
1) B + W 77mm #110 3.0 (1000x) Neutral Density Glass Filter
2) Hoya 77mm Neutral Density ND-400 X, 9 Stop Multi-Coated Glass Filter
At Amazon B+W 77mm is selling at $99.95
Hoya 400 is selling at $158.85
I understand many people said B+W filter quality is solid and good.
Please kindly advice.... thanks...!!
