JJC ALC-LX100 AUTO LENS CAP is a creative product designed by JJC company. This lens cap is designed for Panasonic LUMIX DMC-LX100 and LEICA D-LUX(Typ 109) Camera. This auto lens cap adopts an ultra-slim design and easily screws onto the lens. The three leaves will open automatically with the extension of the lens, so you will not need to remove it from the camera when you want to take photos. You don’t need to worry about losing your lens cap any more. In addition, the auto lens cap will not cause vignetting. The three leaves will automatically close with the retraction of the lens. At this time it protects your valuable investment from dust, moisture and scratches. When a filter is attached to the camera lens, JJC ALC-LX100 is able to close perfectly, while the Panasonic DMW-LFAC1 is not. With its easy installation feature, the auto lens cap is approachable for both new camera users or professional photographers. JJC ALC-LX100 replaces Panasonic DMW-LFAC1 auto lens cap.
