Der 90-Grad-Adapter ist eine günstige Alternative zu echten Periskop-Objektiven. Für bestimmte Shots ausreichend, aber mit optischen Kompromissen.
Optical adapter for 90-degree light path deflection—between lens and camera or for EVF. Enables periscope-like effects or ergonomic viewfinder positions.
What is a 90 Degree Adapter?
The 90 Degree Adapter is an optical accessory that redirects the image path by 90 degrees. It is mounted either between the lens and camera (for periscope effects) or on the EVF (for ergonomic work). A budget alternative to professional periscope systems.
