Where can I buy the Inspire 1 Pro with the X5 camera body? I don't want the stock 15mm DJI lens. I've looked everywhere and can only find the package that contains the stock lens. Also, I currently own the Inspire 1 version "D". Do you think it's necessary to upgrade to the Pro version (v2) to support the heavier X5 camera? I know DJI has said that it can simply be added to the D version, but I'm worried about reduced flight times due to the heavier weight. I apologize if this topic has already been discussed. If so, please direct me to the appropriate thread.
