Hey guys

I have a 7D + Sigma 8mm and was wondering what you thought would be a better option for vfx work (IBL), since im using the fisheye on a cropped sensor. The NN5 or the R1?
I've read suggestions to tilt up 5 degrees to cover the zenith better but obviously this means less coverage on the nadir.

I'm after something that is hopefully repeatable in PTGui and that I won't have to worry about too much when on set.
I really like the sound of both nodal ninja products, however i'm wondering what the least amount of pics I can take for time purposes. I wonder if 4 pics around at 5 degree up and then a 5th 90 degree down nadir?


Cheers!

I'd use the NN5. You can't take the down shot on the R1 unless you reset the nodal point. I've got a UK customer who is an SFX studio in London and they use the NN5 for their IBLs.

Hi Badders

Thanks for your reply. I'm leaning towards to NN5 too. I think I should look at getting the nadir adapter and a quick release plate so I can assure more repeatable results.
Do you know what the difference (if any) is between the arca style and nn quick release plates?

The Arca style is for use with Arca Swiss plates while the Nodal Ninja QRS is for use either with the supplied nodal Ninja plates or a standard Manfrotto quick release plate.
