A holding assembly for a camera system comprises a first pair of support rods connected to the camera system and extending from the camera system and at least one functional device. A first support element having at least a first pair of recesses on a side of the support element pointing towards the pair of support rods and at least a pair of noses is attached to the first pair of support rods by inserting the first pair of support rods into the first of pair of recesses. A second support element with at least a second pair of recesses on a side pointing towards the first support element holds the at least one functional device and is attached to the first support element by inserting the pair of noses on the first support element into the second pair of recesses in the second support element. The invention, thus, provides a holding assembly which allows an easy attachment and detachment of a functional device to and from a camera system, is convenient in its handling and reliable in its operation.
