This will depend on the lens you are using!
If you are use standard lens you should have a 18 position
If you are using fisheye (Two shot) for Panoweaver Standard Edition then 2 position detent ring. 180 degree for each shot.
If you plan to use fisheye (three shot) for Panoweaver Pro Edition then you will require 3 position detent ring (or any ring you can devide by 3, Example 18 position detent ring using position 6, 12 and 18.) 120 degree for each shot.
* The 3 position may not be listed on the Kaidan website but it is available!
I personally would buy these 3 different detent rings.
Hope this helps you out.
Kaidan told me I have to buy a 14 positions detent ring with the WC E63 converter. So I always shoot 14 photos, and I stitch them with VR-Worx.
Sometimes it is better to stich 14 photos, sometimes it is better to stictch only 7. That's the advantage of the 14 detent ring.
