What the thread found

• A DSR-570 can be mounted on a Flyer sled with wireless follow focus and iris control, though weight and power distribution require careful consideration.
• The Flyer sled comes with a 2-pin Lemo to 4-pin Canon XLR power cable for the camera.
• The camera's Hirose connector is limited to 1 amp output and should not power larger motor drivers; use the Anton Bauer tap on the camera handle instead, which provides 50 watts.
• Removing the camera viewfinder and routing on-screen displays to monitoring outputs helps reduce weight on the sled.
• Using PAG C-50 or NiMH batteries rather than lithium batteries may help achieve better balance.
• Heavy lenses like the Canon J11 can push the total weight over acceptable limits for the sled.
• A custom Y-cable with XLR4 connectors can split power to simultaneously feed both the follow focus unit and other accessories.
• The Flyer dovetail plate does not fit certain aftermarket Sony plates like the Baer Bel model.
• Direct mounting the Flyer dovetail to the bottom of the DSR-570 using a high-quality screw is possible.

Depends on

• Weight balance depends heavily on the specific lens model used.
• The power solution described assumes standard wireless follow focus and iris control systems; different kits may have different power requirements.
• No definitive confirmation provided that all wireless follow focus and iris systems will work reliably on the Flyer sled.
• Discussion does not address all potential power management scenarios or confirm maximum usable accessory payload.
