The DLC SensorVu™ Loupe is an innovative product that allows you to check the condition of your sensor cell (CCD/CMOS) using the built-in superbright LEDs with 5X magnification. If you need to clean the sensor, simply raise the loupe to the elevated position using the 2X magnification lens. This will give you enough room to clean the sensor cell surface and see exactly what you are cleaning. Fits all DSLR cameras, including Sony.
