Sigma 8-16mm ND without Matte-Box

Hi Folks,

It's hard for me to decide which wide-angle lense to choose for the EF-Version I preordered.
In my opinion there are just two good options out there (at least until now).

The Tokina 11-16mm and the Sigma 8-16mm. I think there's truly a great difference between 8mm and 11mm on the bmcc (field of view). Although the Tokina stands out for it's F2.8 I kind of like the way of how wide the Sigma looks ( ) . Shooting with the Sigma on Night Shots is nearly impossible. But it's also hard on shooting day exteriors (noon - afternoon) without the use of a Mattebox with filter trays. For documentary work I don't want to use a mattebox and prefer going with a heliopan Vari-ND. Are there any options out there to help this problem out without changing the 180Degree shutter-angle?

What are your thoughts? I know there is lots of footage out there (from both lenses) but there's not a comparison.

That is a AWESOME video.

M... You don't want to use a matte box, but you want a wide angle. You want a wide angle but impossible to shot low light.

That is something all we have to deal for now. New lenses are been developed right now, the only thing we can do is to cross our fingers and hope for the best... :?

If you are gonna be using the camera in a controlled environment, get the sigma. if is not, then there is just one more choice... Tokina.

On very wide angles you'll probably get a strange triangular vignetting with a variable ND.

This is because variable ND's are actually 2 polaroid filters that rotate against reach other.

You would be better off with standard screw in NDs. You could also stack them without an issues as the BMCCs sensor is only seeing the centre of the lens.
