UV protection filter for my "Fader ND" ( Thread size confusion )
 

I haven't been able to find any information about this.

I already have my fader nd coming home, and i would like
to buy a UV filter to protect it from dust and scratches.

i understand the glass is bigger than the filter thread.

the fader nd i bought is 67mm (72mm glass).
does this mean i have to buy a 72mm UV filter?
or should i buy a 67mm UV for the 67mm version ?


sorry if it's a dumb question but i don't have the filter in my hand.
the pictures don't help me much.


Thank you.

Roberto.

If it were me, I would not stack a UV filter over your ND filter for "protection".
But that is just my opinion based on over 40 years of taking pictures, 30 years professionally.


Good Luck!

Do you know if It's possible to attach another ring in the fader nd?

I would like to buy a hood or a mattebox at least,
but i don't know the filter size for the 67mm.

i found this inexpensive matte box
The CineCity*::*Matte box*::*Matte box without rod support*::*Matte box with french flag for DV and HDV cameras
and i have to choose the size of the ring to be attached to my fader nd.

i know it doesn't make any sense, cause it's a mattebox, i shouldn't have the fader nd in between if i'm going to use a 4x4 ND filters.

but i would really like to have this cute mattebox in front of my fader nd.


Thank you very much

The matte box appears to be a screw in type, that would not really work with a filter that needs to rotate.

Also this matte box does not seem to be able to rotate its filters, at least one filter should be rotatable in a decent matte box for graduated filters.

you're absolutely right.

I uderstand Vari ND have another ring after the rotating glass wich don't turn if you hold it with a screw in type ?

is this correct?

Like David mentions, there is no need to use a UV filter with an ND filter because the ND filter will protect from UV rays.

A PL filter also acts as a UV filter.

Only us a UV filter on its own and not with a second filter or stacked filters.

If you only have one lens, then buy a UV filter to fit that lens thread.

For photographing/filming static landscapes that have wide light differences between foreground and background (such as sunlit mountains and foreground flowers in the shade) it is far better to use Graduated ND - so that the whole frame is exposed to similar levels of light and easier for the film or digital sensor to cope with. The Grad filters come in varied Neutral densities to match the scene (or also in graduated colours if you need to change visual atmosphere). Square adjustable filters generally work better than round filters for Grads.

If you have many lenses it can be cheaper to buy a filter for the lens with the largest filter thread and use step-down filters so that same single filter can be used on many lenses.

However, in reality this is not always viable if you change lenses often. So to avoid the need to be constantly changing filters, I normally have separate filters for each lens.
