The newly designed JJC SRB Series Deluxe Soft Release Button is made of pure copper and features a microfiber leather surface that ensures a soft and pleasant feel on the top of your camera. Simply screw the SRB Soft Release Button into the thread of the shutter release to enjoy a gentle and stable release operation. It also enhances the appearance of your camera, giving it a stylish and elegant look. Once mounted, you can feel the soft and pleasant surface with every photo you take. Additionally, this Deluxe Soft Release Button is available in 16 models. Two rubber rings are included in each package, primarily for Fujifilm X-series cameras, to ensure a secure attachment. If your flat camera shutter button does not have an internal thread, you can use the JJC SRB-M (optional) to facilitate the mounting of the JJC SRB.
