Camera converter explained – How to use telephoto & wide-angle lenses

Converter – greater range, greater flexibility

🔧 Function & Types

What is a converter?

A converter (also called a teleconverter or adapter) is an accessory that is placed between the camera and the lens. Depending on the type, it extends the focal length, establishes a connection to a different lens mount, or changes the distance to the sensor (e.g., macro).

What does a teleconverter do?

A teleconverter multiplies the focal length of your lens – for example, a 100 mm lens becomes 200 mm with a 2× converter. This usually reduces the aperture (e.g., by 1–2 f-stops).

What is an adapter?

An adapter allows you to combine lenses and cameras with different mounts – for example, a Canon lens on a mirrorless camera. There are simple mechanical adapters and those with electronic signal transmission.

📌 Compatibility & Limitations

Do all converters fit all cameras?

No – the connections and distances (flange focal distance) must be exact. Adapters for, e.g., M42, Nikon F, or Canon FD often only work manually. If you have any questions about compatibility, please feel free to contact us.

What does loss of automatic functions mean?

With simple adapters, autofocus, aperture control, or image stabilization are lost. Exposure and focus are then set manually.

Are there quality differences between converters?

Yes – especially with teleconverters. Good models largely preserve the optical quality, while simpler versions can lead to image defects.

🧠 Tips for use

What are macro extension tubes used for?

Extension tubes increase the distance between the lens and the sensor, thus reducing the minimum focusing distance. Ideal for macro photography with a standard lens.

How can I safely mount adapters?

Carefully attach the adapter to the camera and lens, without force. Some adapters require a release pin or alignment with markings.
