ASSESSING PAYLOAD FOR DJI RONIN CAMERA STABILIZERS July 17, 2019 Version 1.
A key parameter for camera stabilizers is the weight of the camera and lens, otherwise known as the payload. A stabilizer’s rated payload alone can roughly indicate the overall performance of the product. Rated payload is subject to multiple factors and has complex evaluation criteria. This article will elaborate on DJI’s definition of payload. 1.
carry the load effectively or operate normally. There are also specialized lenses on the market that cannot be used on stabilizers even of moderate weight, such as the Sony E PZ 18-200mm f/3.5-6.3 OSS. d G Motor torque = downward orce on the lens (G) × distance from the lens to the axis of the motor (d) SPACE FOR BALANCING The heavier the camera and lens, the more movement space the configuration needs for stabilization.
STABILIZATION PERFORMANCE Even if the above two conditions are met, it is still necessary to observe whether the gimbal can provide sufficient stabilization, which is usually judged by subjective experience. DJI calculates the actual stabilization performance by tracking and modeling a feature point in test footage and calculating its offset frame by frame.
4. CONCLUSION The rated payload of a camera stabilizer must take into account the center of gravity of the camera and lens, whether there is enough space for balancing, and whether it can provide sufficient stabilization. The heavier the rated payload, the better the compatibility and anti-disturbance of equipment combinations. However, a heavier payload also requires more space within the gimbal for the different combinations to achieve balance.
