The SensorScope® DSLR Camera Sensor Inspection Device is a specialized tool that allows you to thoroughly inspect your digital SLR with the most precise eye. Although avoiding the need to clean your image sensor altogether would be ideal, excessive environmental exposure will eventually result in discoloration & streaking in your photos. Built to resemble and fit perfectly on top of any standard SLR lens, the portable SensorScope Inspection unit is equipped with 5x magnification and 4 ultra bright LEDs to illuminate the surface of your image sensor and expose even the most minuscule particles. With the quick switch of a button, the SensorScope magnification unit optimizes user visibility so that you can proceed with caution in cleaning of your camera. If it isn't dirty, simply don't clean it!
