I bought my NN3 in 2008, tried it a few times but was never happy with the setup.
I recently upgraded it by adding the RD3L 6-8-30 Rotator EZ Leveler II (VERY nice product that one is).
I'm trying the setup with a Canon 400D and the Canon 15mm Fisheye, have spent days trying to get the alignment right. I'm close, but just not close enough for perfection every time.
The guide at johnhpanos.com is good but I still feel I don't have it quite right.
Searching these forms I've seen others trying to figure out the setup of this camera/lens combo but never any answer.
Anyone have the numbers for this camera/lens combo?
