Q: 7. I have 67mm polarized filter that i want to use on lenses that are smaller then 67mm(48-67) ..... which rovering to choose ? the 67mm or the 77mm ?

Q: 10. Hi ! Video guy question ! Will this let me go f1.8 on 1/50 and 200 iso on a bright sunny day ? Or I need the other version. Thanks

A: Unfortunately, we cannot be sure exactly how much density you will need without knowing the original exposure or the ambient light level. However, I would guesstimate that, by using the Sunny-16 rule, I would recommend you would need at least a 10-stop neutral density filter for your usage needs, so the above option would not work for your usage. If you are looking for an alternative that would work, I would recommend the Aurora-Aperture 77mm Power XND Mark II Variable ND 1.5 to 3.3 Filter (5 to 11-Stop), B&H # AUVND322K77, or the Haida 77mm NanoPro Variable Neutral Density 0.9 to 3.0 Filter (3 to 10-Stop), B&H # HANPVND77, for your usage needs.
