I am using NN3 with canon 350d and 18-55mm lens. I thought the settings provided in the table on the website were incorrect for my camera and lens combination as I still saw stitching errors. After working out the settings for myself I realised I have arrived at the same settings as those listed in the table (51mm for the lower rail and 89mm for the upper rail). However when i stitch the photos together in photostudio I still see significant parallax error. I would be very grateful if anybody has any thoughts as to what is going rong. I'm off to croatia in a week and would like to have it up and running by then if possible!!
