I currently use the NN3 and RD16 rotator for my normal 360s which works fine but i want to have a play with pole photography and I am thinking of getting the ultimate R1 with ring for my Olympus E620 and Olympus Zuiko 8mm digital lens, however i want to be sure that i will be able to get the zenith and nadirs OK. Does anyone envisage any problems using this setup for this as i have seen some comments on this forum about issues with taking the zeniths and nadirs and the cameras fitting or knocking against the support with other brands, any help would be greatly appreciated as it an investment and I want to make sure I am getting the right kit.
