I am a newbie at panos. I just received my NinjaNodal 3MII.

How do I calculated the number of stops I want in order to choose the correct detent ring.

For example: If I want to shoot a 360 degree panorama using a Canon 40D with a Canon EFS 17-55mm IS USM lens set at 17mm. The 40D has a 1.6 crop factor.

1. How do I find the angle of view for this lens?

If I divide 360 by that angel I will get the number of exposures for a full cylinder without any overlap.

2. How do I calculate the number of exposures for 40% overlap?

3. Would I multiply 360 by 1.4 and then divide by the angle of view?

4. How would calculate the number of exposures for 50% overlap.
