Using a TIFFEN POLARIZER Filter on the DVX100A

Can anyone help me out--

For the DVX100A -- should I get a

72mm Circular polarizer

or a

72mm thin wide angle Circular polarizer ????


What is the difference??

THANKS :thumbup:
 
thin polarizers are to attach to a wide angle lens/adapter, to avoid vignetting. go with the regular 72mm circular if you're attaching it to your dvx.
 
Thin polarizers are also used when you're "stacking" filters -- i.e., you already have a star filter or a UV filter or an ND filter or something like that attached, and now you're going to add a polarizer on top of it... that can lead to vignetting (where your lens actually sees the metal frame of the polarizer in the shot). So the thin polarizers do away with filter threads on the front, so they can be thinner -- i.e., they stick out less far, so they won't intrude in your shot.
 
that said.. you gotta remember there are no threads on the front of the thin polarizer, so you cant put any filter or accessories (such as the matteblox mattebox) in front of it. same goes with thin UV filters, if you know you will never put something in front of them they are fine, but if you do your SOL. Thin UV filters also can be a pain to get off because there is a little less to grab onto.
 
And also, you won't get the Vignetting if you zoom in a tad. And if you put a step up from 72mm - 77mm you can stack a few filters w/out vignetting, but at the loss of being able to use the stock sexy lens shade.
 
From my experience use a linear polarizer with the DVX100...Century optics has confirmed there were problems/complaints when using the circular polarizers on the DVX (Although I'm not sure if this applies to the A version).
On any other video camera my understanding is circular doesn't really make a difference. Definitely spend the money on a Tru-Pol (Schneider) or Ultra-Pol (Tiffen) for maximum polarization effect.
FWIW that's my 2cents,

Dear Brian:

I am a little puzzled by your post " Century Optics has confirmed there were problems/complaints when using the circular polarizer on the DVX. "

While I do remember seeing some posts about some things that the poster thought might be caused by a circular type polarizer, my posts have always been about the fact that while a circular type was techinically best on video cameras with prism type beamsplitters and some metering systems, we were not aware of anyone using a linear polarizer on the DVX complaining of problems, which is the opposite of your posts implication.

Just striving for clarity and accuracy, If a circular polar is mounted with the wrong side facing the subject that they will not work properly. This would not be possible with a screw in type filter unless the glass was put in the cell backwards. The problem is more common with a unmounted rectangular filter on round filters in unthreaded cells (series 9, 4 1/2" 138 mm etc) but the filter should be marked showing the correct orientation.
