The LC-35X5 from Portabrace is very popular for most small handheld cameras (fits lens shades 3 1/2" x 5" approx). The lens caps feature a quick-connect buckle and tether to keep them securely fastened to your camera, bag, or belt-loop. The exterior of the Lens Cap is made using waterproof Nylon Taslan material that keeps out unwanted rain, splashes, or dust and debris. The elastic opening provides a secure grip around the lens shade.
There is a built-in White Balance Card that provides both structure to the Lens Cap and a convenient focal point for white-balancing. There is also a small interior pocket that can be used for carrying lens-cleaning tissue or as a convenient business card holder.
