Hi - I'm a professional photographer getting ready to dive into the world of HDRI for 3D for a 3D artist I work with. I've been researching different pano heads & related equipment and would just like to hear the arguments actual users might present in favor of Nodal Ninja gear over the competition. Any comments on ease of use, deflection (from weight of camera), features, etc. that you think are weak points or advantages would be greatly appreciated! I know this might seem pretty general, but I'm not looking for a comprehensive review - just pros & cons from users here.
