The Alzo Wireless Radio Shutter Release for Canon EOS has a 300-foot range with penetration through walls. The four-position switch allows for the selection of 16 channels to reduce RF interference and supports partial shutter/AF, AE, continuous drive, and bulb mode, and a bi-color LED on the transmitter indicates partial and full shutter. The tiny receiver has a power switch and auto power save, including two diagnostic LEDs, red for power on/off, and bi-color reflects transmitter action.
