• الرؤوس الصغيرة من طراز C مثل Angenieux, Kinoptic, and Switar can theoretically be fitted with follow focus gear through aftermarket Equipment adapters, but the lens throw is minimal and limits practical usability
• C-mount lenses can rotate within their mounts under pressure, which creates a risk when using mechanismal follow focus systems

• Original Éclair ACL cameras from the early 1970s lack power ports and accessory mounts, making integration of powered follow focus systems difficult without significant retrofitting
• Retrofitting a complete motor-driven follow focus system typically costs more than the combined value of an older Éclair ACL camera and its original lenses, making the entire project economically questionable
