You could use several of these scenarios:
1. Operational conditions such as: wind load, camera weight? [this should be very small]
2. Impact load because falling from your grip (assumed 6ft?) [this more likely to govern]
3. Pressure (the pole fell to ground and got crushed by a person) from 200 lb loading?
Another interesting analysis to run would be to establish the natural frequencies. If these turn out to be fairly low, then you are going to have lots of trouble taking good pictures.
