Looking up 3.5 mm audio jack to lightning adapter I find they are available.

Got it. Thank you Catherine.

Should I be able to use Helicon Remote to see LiveView on my iPad Mini 4 from my Nikon D7100 when using FB Tube? As I understand it, FB Tube doesn't communicate with the camera, it just receives a shutter signal and steps the lens. So I would expect I should still be able to use Helicon Remote to se...

Instructions say to plug FB Tube cable into headphone jack. iPhones from 7 to more recent don't have a headphone jack. They only have a lightning jack. Does that mean iPhone 7 on up can't use the cable? How do we configure the tube?
