Does anyone know of any 175mm lens I can use on the Inspire2? with the X5s

Smith, sorry to tell you that X5S does not support 175mm lens. It may make it lose balance. Here are some recommended lens:
Panasonic Lumix 15mm/1.7
Panasonic Lumix 14-42mm/3.5-5.6 HD Power O.I.S.
Olympus M.Zuiko 12mm/2.0
Olympus M.Zuiko 17mm/1.8
Olympus M.Zuiko 25mm/1.8
Olympus M.Zuiko 45mm/1.8
Olympus M.Zuiko 9-18mm/4.0-5.6
Thanks for your support.
