I have performed basic operational checks such as taking pictures, using the flash, and reading cards, but as this was done by an amateur, there may be oversights. Please be aware of this. The battery is included, but as it is a consumable item, its condition is unknown. Please replace it at your own expense. Due to the age of the item, there is no warranty of any kind. It is sold as-is. Please check the condition in the images. Thank you.
