• A practice cage with a compact camera such as a Sony A7S in Super-35 mode paired with an 18–50 power zoom is a proven configuration for training, with 50 mm focal length considered an ideal middle ground.
• Alternative setups include a practice cage with a camcorder, or used professional cameras such as a Sony F350 or RED Scarlet.
• One operator built a custom dummy housing based on a broadcast camera using 3D printing, fitted with a 15 mm rod at the front to mount a camcorder and weights that simulate the balance and mass of a broadcast lens.
• The total weight of the rig is more important than the specific camera model when training.
