The Tough E-Mount LT Replacement Lens Mount for Sony NEX/E-Mount Cameras from Fotodiox updates their previous Tough E-Mount by incorporating extra flanges to reduce light leaks. The Tough E-Mount LT, which stands for Light Tight, works just like the original in that it replaces the manufacturer's two-piece NEX mount with a sturdy one-piece brass mount that eliminates wiggling, especially when using heavy telephoto lenses, and prevents damage to the camera's mount.
The all-metal Tough E-mount LT is designed to be more durable than mounts that have plastic components, reduce possible light leaks, and provide a tight and secure connection between the camera and lens. The Tough E-Mount LT is made from chromed brass and retains infinity focus.
