Cool, i'm gonna buy one.
And does anyone know a Mattebox solution(french flags) for this lens?
I know 3 filter solutions (Lee,Lucroit and this new Fotodiox) but i would need 3 flags to avoid the huge flare that this nikkor has.
 
I just ordered a Vocas 325. It should be in this week. I will let you re any fit/flare/vignette issues. However, I think I will pick up the new Fotodiox as well.

I don't believe the 14-24 will work with any mattebox without vignetting.

From Steve Gibby (but using a Ruby modified 14-24):

"We found that at 14mm the Ruby 14-24 shows a small amount of the Red matte box on the right and left edges. I simply pushed in to half way between 15mm and 16mm and the easily lost the matte box edges. The 14-24 is a full frame 35mm lens. Images from the lens are very crisp, good contrast, and clean. I expected that because I've used the stock Nikon 14-24 on Red One with excellent results."

And from from Jacek Zakowicz, at OptiTek:

"I checked the 14-24 for vignetting with filters:
It will work with Red sensor (current one) when you use 4x5 filters(ARRI LMB5 clip on?)
6x6 filters will provide full frame(24x36mm) coverage (LMB3?)
The filters were right up against the front of the lens- I haven't checked for stacking more than one.
The front of the lens is 96mm diameter so you'll need:
1. 96mm adapter plate for the mattebox (?)
2. or a bellows that steps down to 96mm for swing away
3. step down split ring to 96mm for a clip on."

I am still going to try it-w-the Vocas, but I need to get some "nuns nickers" and I will let you know how it goes. Even if I have to push to 15 or 16mm, I'll be happy with that.

I wish you a good luck with it, i hope to hear good news about you soon
 
Yes. However, I don't think that the Nikon 14-24 is a good candidate for the clip-on features on the Vocas mattebox. The lenshood appears to be made from either a plastic or composite material. I am afraid that if the mattebox was tightly clamped on the lens hood it might break or crack. It might work with rods and nun's knickers. I will play around with it tomorrow and hold the mattebox with the lens stuck through the 105mm opening to see (in a very crude and unscientific way) if there is any vignetting.

Good luck! It would be great to watch some pictures about the setup...:smile5:
 
Here are the results of the quick and dirty test of the 14-24 on the Vocas 325. Since I am waiting for the delivery of my Scarlet, I tested the 14-24 on a full frame Nikon D700. As I mentioned, I was not inclined to clip the mattebox on the lenshood for fear of damaging the hood. Instead, I removed the step-down ring from the mattebox and inserted the 14-24 into the 105mm rear opening of mattebox. However, I first put several wide produce rubber bands around the lenshood to act as a poor man's donut/gasket. With that done, the lens would fit into the rear opening without much of a gap. But, I still had to hold the mattebox with one hand in an effort to keep it centered and on axis. (Admittedly, very crude, and please keep that in mind when considering the results below.)

With both filter frames attached, and lens pushed up to the second filter frame housing, here are my observations:

14mm: Slight to moderate vignetting at lower left and right corners
15mm: Slight vignetting at lower left and right corners
16mm: Vignetting still visible but starting to diminish
17mm: Vignetting almost gone
18MM: Vignetting gone

I then removed the second filter frame, which allowed the mattebox to slide slightly closer to the lens. Here are my observations with one filter frame:

14MM: Very slight vignetting at lower left and right corners
15mm: Vignetting almost gone
16mm: Vignetting gone

I would be very reluctant to use any sort of clip-on mattebox with the 14-24. Using 15mm rods and nun knickers-w-the Vocas should result in a usable focal length of 16-24, provided only 1 filter is used. If additional filters are used, I would expect the usable focal length to begin around 18mm.

Then, just for fun, I did mount the Vocas on a CY Zeiss 21/2.8, and it clamped perfectly tight using an 82mm step-up ring on the lens. The lens and mattebox (with both filter holders) were then mounted to a Canon 5DII, another full frame sensor camera. No vignetting whatsoever. The set-up was extremely light and could be used handheld all day in my opinion.

As with most things in life, YMMV, and nothing definitively will be known with the 14-24 until the mattebox is actually used on a properly configured Scarlet (or Epic).
