PROMASTER offers a complete line of Remote Release Cables to cover almost every popular DSLR and film SLR. The innovative modular design allows the maximum flexibility in working distances. Many cameras offer built-in infrared remote capability but limit the use of your remote to standing in front of the camera. A wired remote allows more freedom to work from any position. The PROMASTER Professional Remote Shutter Release Cable is fully compatible with all shutter release functions including prefocus and timed exposure.
