So for the last 3 day's I've search this form & spent countless hours trying to get the setting correct for this combination of len & Camera Canon 7D with 17-55mm 2.8 EF-S
reading the form & with my own testing the lower arm is set between 56-58mm
upper arm is where I'm having the issues. no matter where I set it I always get the same results
upper arm set at 60mm
upper arm set at 90mm
upper arm set at 120mm
panoramic software I used was Hugin
is there any other adjustment I can try?
