There is always a possibility that the drone will crash while you are learning to fly it, so it is better to buy a cheaper version first. Photographers who are well-versed in piloting a drone by themselves can opt to buy more advanced drones that have the capability of carrying a larger camera.
Some of the most popular models of drones that are currently being used for commercial photography include the DJI Phantom series. If you are confident about your drone flying skills then you can even go for the Iris by 3D Robotics. These drones may cost you around $800, but they are worth the cost. The quality of photos that you get from these drones is amazing.
