Due to space constraints, it may be necessary to configure the camera and lens in a compact manner.

In such cases, compactness can be achieved by choosing an S-mount lens that is smaller than a C-mount or CS-mount lens.

 

 

In order to use S-mount lenses, you need to attach a conversion adapter to the camera.

 

 

However, there is a caveat.

With S-mount lenses, the focus is adjusted depending on how well it is inserted into the camera.

Cameras usually have an infrared cut filter or a protective filter in front of the sensor.

In some cameras, the distance between the filter and the lens mount is close, and the lens may interfere with the filter when focusing, resulting in a lack of focus.

 

 

 

It is necessary to actually try and check whether the S-mount lens can be attached and used with the camera.
