The RFN-4s Wireless Remote Shutter Release for Select Fujifilm cameras from SMDV is a reliable remote control and wired shutter release that will work with your Fujifilm cameras from up to 260 feet away. Ideal for sports, wildlife photos or self-portraits, the kit contains a transmitter and receiver that are small enough to easily fit in a shirt pocket. The system works on the 2.4 GHz frequency for reduced radio interference and extended operating range, and since radio signals pass through obstructions you don't need to position them in line-of-sight.
