ND Filter for Tokina 11-16

[Santos Ramos]

Hello everyone! I just got the scarlet but I can't use it till I get the monitor and power!

The details:
I'm planing to do a lot lot of walking/hiking to shoot stock footage.
I will be shooting during the mornings ( 6am -10am) and afternoons ( 2pm to sunset ) and keep the aperture around f5-f8 @ ISO 800.
A usual hot summer clear sky day in the DMV (the "Sunny 16" rule)
Screw-in filters would be best for my needs! or clip-on matte box would be great! I don't want to hike old rag with matte box and rails!
The lenses I plan to use - Tokina 11-16 and Canon 17-40
The questions!
Would these ND filters cover my needs? Hard question and guesstimate here.
0.6 ND (no IR filtration)
0.9 ND (no IR filtration)
1.5 ND+IR

The Tokina and Canon take 77mm filters. What I would like to know is, will they vignette at any focal?

If I get the 4x4 ND filters:

Will they vignette at any focal length with only the Lee filter holder system using the standard 77mm Lee adapter?
Will they vignette at any focal length if I use a matte box?

Here is the matte box I would get.

Thanks for the help!

I believe the 4x4 will vignette.

Dont quote me just learned that from past posts.

Im using a screw on as well as a RED MATTE BOX with the Schneider RED Essential Kit.

Thanks Eric,

Do you get any vignetting with the screw on filters?

Are these the filter you are talking about?

They look nice!

Not with a Tiffen 77mm ND.6 Filter on all my Rokinon Cines and Tokina 11-16mm.

Are you shooting 4k or 5k (video or stills)? This makes a difference because the sensor size is smaller/bigger depending on which format. I've had quite a bit of success with just using a screw-in variable ND. The problem you run into is lens hood, since the variable NDs usually step-up thread sizes (meaning the lens hood doesn't fit over, meaning matte box... meaning more weight/kit to slag around with you on the hike).

Honestly, because you're probably going for infinite focus (I presume, since 11-16 is essentially always infinite focus and/or landscape shots), you'd likely be able to get away with a bit less ND, knowing that if you need it, you can just stop down (e.g. only a 1.2+IR). I understand wanting to stay 5.6-8, but give or take a stop or two shouldn't mess things up too badly.

Conversely, if you're used to hiking with DLSRs, you might be in for a bit of a rude awakening. DSMC cameras, while their the lightest Digital Cinema cameras, are still incredibly heavy compared to even the beefiest SLR. Fortunately there are a number of guys on this forum that shoot some pretty badass nature videography that can probably give you the skinny on keeping your rig...well... skinny (hopefully they chime in, if they see this thread).

Thanks for the tips Mike!

I will be shooting 4K 16X9. I have 2 variable Tiffen but I thought there were not good for Red camera because of the color casting?
Not able to use the lens hood can be a problem so I was thinking about getting a clip on matte box.
You are right about the Tokina infinite focus, I will try it.

I usually bring the 6' motorize slider to the hikes so I may be able to handle the weight of the scarlet.

You could get a separate hot mirror filter the same size as your variable ND... also the colour cast would be diminished with a higher-end vND (although not entirely gone at anything past a ~0.9)...

HOLY crap... I didn't realize you'd be carrying a slider as well... I have a tendency to want to be as light as possible (even in studio). If you're used to lugging a slider, I don't think the camera will be what weighs you down.
