Fully functional. Purchased 1 year ago and am the original owner. 

***Please note the scratches on the plastic casing around the sensor. Those scratches were accidentally created while using focal reducers, but the sensor is free of any damage whatsoever as you can see in the pictures. It perfectly retains its original image quality. 

Comes with: original battery, charger+usb cable, box/documentations, tempered glass screen protector (installed immediately after initial purchase and never taken off), & body cap.
