This SR-2 remote switch is fully compatible with Canon RS-80N3. It prevents camera shake for super telephoto shots, macro photography and bulb exposures. Handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure. The remote switch works just like a shutter button, enabling halfway or complete pressing. It also has a shutter-release lock. With the EOS-3's Custom Function No. 12 (mirror lockup), camera shake can be further reduced.

• EOS 1V, 1V HS
• EOS 1D X, 1D X Mark II, 1D X Mark III
