I have added in several related "add-ons" to enhance your experience with your new camera.  I've included a battery charger and six batteries($60 each - Canon LP-E17). The EOS RP  extension grip ($80.00)  seamlessly attaches to the main body of the camera and provides great control and comfort while you adjust the beautiful pictures you are about to shoot.  Several of my pictures show how this fits together.  I also included a wide and comfortable PEAK DESIGN shoulder strap ($80.00) and a couple CUFF hand straps ($40.00) to comfortably tether you to your artistic tool.  The last of the add-ons is a lens mount adapter ($99.00) which enables older Canon EF lenses to fit and work seamlessly on your RP.  This adds only an inch to your old lens length, but saves you from condemning your old lenses to obsolescence.

I hope you will find these additional items useful in your transition to using the RP.
