I'm having some difficulty with my RT Motion Latitude. I'm trying to use EF lenses (internal motors.) I have a thumbwheel setup, but no wireless hand unit. I'm unable to control either the focus or the iris using the thumbwheel, but have no trouble doing so using Foolcontrol. I'd like to be able to check to see if it's as simple as a faulty cable. I'm in L.A. is there anyone who might be able to help me troubleshoot? Ablecine, a REDuser with a similar setup? (Or a hand controller?) Any thoughts? Thanks in advance.
