The cable release works perfectly, the workmanship is alright. The "JCC" brand seems to be a store brand of enjoyyourcamera.com, is likely to get even with this provider. Is photographed as the camera shutter: half press - focus, full-press - trigger. Also can be in Bulb mode (hiding in M mode: the trip time to be longer than 60 s Set) button of notice to allow long exposures. The cable release is a total useful to easily trigger on the tripod and reduce especially in Nachtaufnahhmen the shake, the mirror lock the camera should also be enabled. Have decided against an infrared trigger, but since I'm rather behind the camera. Conclusion: good and cheap for night and tripod
