4. The device according to claim 1 , wherein the spring corresponds to an extension spring or a compression spring.

5. The device according to claim 1 , wherein the second point and/or the third point of the lever arm are configured to be movable via one or more threads.

6. The device according to claim 1 , wherein the second point and/or the third point of the lever arm is configured to be movable based on the lever arm comprising a threaded rod and the second or third point of the lever arm having corresponding threads.

7. The device according to claim 1 , wherein the one or more instruments comprise a camera.

8. The device according to claim 1 , wherein the harness comprises shoulder straps and a waist belt.

9. A method of using an optical instrument holding device, the method comprising:

fastening the optical instrument to a first portion of a string, wherein a second portion of the string is attached to an adjustable counter force device in order to provide a counter force on the string; and

utilizing a harness, wherein the harness is operally connected to an arm, the arm comprises a first portion being fixed in relation to the harness, and a second portion for supporting of the string,

adjusting the counter force applied to the string by moving a lever arm of the counter force device such that the lever arm pivots relative to a support via at least a second point attached to a first point of the string and a third point attached to a second point of a spring, wherein a first point of the spring pivots relative to the support, and the second point and/or the third point of the lever arm moves along the lever arm.

10. The method according to claim 9 , wherein adjusting the counter force is performed using pulley system comprising at least one wheel through which the string is pulled.

11. The method according to claim 9 , wherein the second point and/or the third point of the lever arm are moved using one or more threads.

12. The device according to claim 1 , wherein the second point and/or the third point of the lever arm are moved via the lever arm comprising a threaded rod and the second or third point of the lever arm having corresponding threads.

13. A camera system, the system comprising:

a camera;

a harness;

an arm;

a string, wherein the arm comprises a first portion being fixed in relation to the harness, and a second portion for supporting of the string, and the string comprises a first portion and a second portion, the first portion of the string being arranged to fasten to the camera; and

an adjustable counter force device, wherein the second portion of the string is attached to the adjustable counter force device in order to provide a counter force on the string, and the adjustable counter force device comprises:

a spring,

a support,

a lever arm, wherein the lever arm comprises a first point pivotably attached to the support, a second point attached to a first point of the string, and a third point attached to a second point of the spring, wherein a first point of the spring is pivotably attached to the support, and the second point and/or the third point of the lever arm is configured to be movable along the lever arm such that a counter force exerted by the counter force device on the string is adjustable.

14. The system according to claim 13 , wherein the adjustable counter force device further comprises a pulley system comprising at least one wheel through which the string is positioned.

15. The system according to claim 13 , wherein the spring corresponds to a gas spring.

16. The system according to claim 13 , wherein the spring corresponds to an extension spring or a compression spring.

17. The system according to claim 13 , wherein the second point and/or the third point of the lever arm are configured to be movable via one or more threads.

18. The system according to claim 13 , wherein the second point and/or the third point of the lever arm is configured to be movable based on the lever arm comprising a threaded rod and the second or third point of the lever arm having corresponding threads.

19. The system according to claim 13 , wherein the harness comprises shoulder straps and a waist belt.
