Has this happened to you?
I just got the NN3 and I am using a Nikon D300 with 10.5mm Fisheye.
I will be shooting 360 panos for EveryScape and they recommend to shoot at 10 degrees down.
But when it's set to anything below neutral the NN frame comes into view in the bottom right hand corner of the viewfinder and since the viewfinder is not 100% I am confident it will really show...
So I am waiting to hear back from the company about what to do, so if you have any ideas please let me know so I can bring them u to EveryScape.
