Objektivadapter ist Teil meiner visuellen Sprache. Ich setze es bewusst ein, um Emotionen zu transportieren und die Geschichte zu unterstützen. Die technische Beherrschung ist Voraussetzung für kreative Freiheit.
Lens adapter enables use of lenses on camera bodies with different mounts or flange focal distances.
Definition
An adapter (lens adapter) is a mechanical or electro-mechanical intermediate piece that allows the mounting of lenses onto cameras with different bayonet systems. Depending on the flange distance difference, an adapter can be purely mechanical or contain optical elements.
Principle of Operation
Flange Distance
The distance between the lens mount and the sensor plane is crucial:
Lens Flange Distance > Camera Flange Distance
→ Simple Adapter (mechanical only)
Lens Flange Distance < Camera Flange Distance
→ Adapter with optics or not possibleExample Flange Distances
| Mount | Flange Distance |
|---|---|
| PL | 52.00mm |
| Canon EF | 44.00mm |
| Sony E | 18.00mm |
| MFT | 19.25mm |
| Leica M | 27.80mm |
Adapter Types
Mechanical Adapters (Dumb Adapters)
- Mechanical connection only
- No electronic communication
- Manual aperture required
- Affordable, reliable
Electronic Adapters (Smart Adapters)
- Transmits aperture values
- Autofocus (partial)
- EXIF data
- More expensive, software updates needed
Optical Adapters
Speed Booster / Focal Reducer
- Reduces crop factor
- Increases light sensitivity (approx. +1 stop)
- Contains a converging lens
Teleconverters
- Extends focal length
- Reduces light sensitivity
- For telephoto applications
Popular Combinations
For Cinema Cameras
| Adapter | From → To |

Perspectives
Director
Bei Objektivadapter arbeite ich eng mit meinem DoP zusammen. Es beeinflusst, wie der Zuschauer die Szene emotional erlebt. Die Entscheidung treffen wir gemeinsam in der Vorproduktion.
Editor
Objektivadapter beeinflusst meine Schnittmöglichkeiten direkt. Ich brauche Material, das im Rhythmus funktioniert und mir Spielraum für die finale Erzählung lässt.
Producer
Objektivadapter hat Zeit- und Budgetimplikationen. Ich plane die Ressourcen so, dass das kreative Team seine Vision umsetzen kann, ohne den Rahmen zu sprengen.
