ProMaster offers a complete line of wired remote shutter release cables to cover almost every popular DSLR and film SLR. The innovative modular design allows 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 cable allows more freedom to work from any position. The ProMaster Wired Remote Shutter Release Cable is fully compatible with all shutter release functions including prefocus and timed exposure.
