2009Forum Follow Focus
Verwendung von Standbild-Objektiven mit Follow Focus-Systemen auf Videokameras
17 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Noch Fotografie Objektive fehlen die Zähne, die Standard Follow Focus Systeme erwarten, statt mit glatten Fokus Griffe, die Workarounds erfordern.
- Applying pressure with mismatched gears can achieve functional focus pulling on still lenses, though the connection may slip and lose calibration.
- Adding a rubber band around the gear increases friction and can improve grip stability on still lenses.
- Adhesive gear strips designed to add standard gearing to still lens focus barrels are available as a solution but require sourcing.
- Wireless follow focus systems generally work better with geared still lenses than traditional wired systems, despite the compressed focus range.
- Many still lenses have continuously rotating focus barrels with no mechanical end stops, which can complicate precise focus repeatability.
- Over-torquing gears on still lenses and adapters risks mechanical damage since many 35mm adapter assemblies are not robustly constructed.
Hängt ab von
- Still lenses with electronic focus linkage rather than mechanical focus barrels offer poor repeatability regardless of follow focus method.
- The adhesive gear strip solution is mentioned anecdotally without specific sourcing information provided.
- No detailed specifications given for which gearing options work best with which still lens types.
- Discussion does not address long-term reliability or calibration stability when using these workarounds.
