set of filters

What's everyone's ideal set of 4x4 filters. I've limited experience with such a matte box and set-up but I know that I want more light management with the camera. Certainly some Grad and ND stuff and some softening... but from here what's necessary and what's filter masterbation and craziness. I'm hoping to get a matte box, rods and filters for 1500 or less.

I think you've just invented a new genre of porn.

I plan to get a grad ND or two and a polarizer... I plan to do my softening/ tint effects in post, for more control.
 
I filter masturebate with a Tiffen Circular Polarizer and a Schneider Enhancer filter. I like pretty colors :)

I have the Formatt matte box. It is definetly not the best, but I think it is one of the best values out there.
 
Thanks guys... Lots to fantasize and plan for here. I'm hoping to get an inexpensive matte box myself and a nice set of filters. I think there will be several options for matte box under 500.. which sounds about right. 2K for a matte box.. just seems way overpriced...
 
Having a full ND filter in front of the lens to increase DOF may at times be useful. Grad NDs and polarizers are essential. An obscure "redhancer" made from rare metals can assist in capturing intense red scenes, such as autumn leaf displays. In general, with the above exceptions, anything that equally changes all light frequencies across all points being captured will not change what is captured in any way that cannot be simulated in post.
 
While we're on the topic of matte boxes and filters, another question. Recognizing the 4x4 filter set-up will create a vignetting issue if using a wide angle, does the 4x5.65 completely solve this issue - or is vignetting still present?

This has financial impacts on filter and matte box costs...
 
The Chrosziel HVX mattebox setup has no vignetting at full wide with 4x4 filters.
 
a .6?? yeah, youd have to check on that. Call up your chrosziel dealer, they could answer it right on the spot. Personally i dont see a problem, seeing as to how far from vignetting the Chrosziel is already, but dont hold me to that i dont have a wide angle.
 
yeah, i've called a few people and i'm getting different responses depending on who i talk to - and some with admissions that they just don't know.

basically, i have some folks saying that a 4x4 won't have any more vignetting than a 4x5 with a wide angle adapter because it's a circle... you still have 2 sides that won't change and that the 16x9 aspect happens in camera - not at the lens. others say, of course you'll have less vignetting...

perhaps we can nail down an answer on this? does anyone have any direct experience or an easy to understand geometric explanation of the topic?
 
okay, so i spoke with the folks at 16x9 and they say they've tested it. that in fact you do see the corners when using a 4x4 box. i tuned into the idea of corners... not top and bottom or sides which clarifies the image for me.

she did not that this isn' the case on all cameras. it depends on the lens and it just happens to be the case on the HVX.
 
A ND will decrease DOF, not increase it. Less light forces wider (lower) aperture, resulting in less depth of field.

We sell ND.3; ND.6; ND.9 and ND Grad filters in both 4x4 and 4x5.65 sizes. You will see vignetting in the corners at the widest focal length if the rotating stage is out of its guides, otherwise your mattebox should be spaced properly from the front lens element to all but eliminate these concerns.

Our 4x5.65 16:9 mattebox will vignette on a DVX100a if you stack any filters (usually a "Clear" or "Sky") between the front element and the mattebox adapter ring. For that reason, we recommend against any stacking on the 100a/b in particular.
