[Description]
- This instrument measures field exposure volume and effective exposure time and contact point’s aperture value for the conventional lens shutter camera and the digital camera, and it simultaneously displays 3 results. In addition, it is possible to transfer measurement data and remotely control the instrument by connecting with computer on the RS-232C interface.
[Features]
Object to be measured:
- 35mm lens shutter camera（LS）or only the shutter part
