Lightweight, high-strength, and resistant to rust and heat. The titanium density is 4.54g/cm3, which is about half the density of steel of the same weight, but twice the strength of aluminum, and can perform well even in high and low temperature environments. The inside of the frame is matte black plated to prevent light reflection. Enhanced CPL allows for shooting with higher saturation than the standard CPL filter.
