>>4033093>>4033155The Z fc's body is constructed from lightweight magnesium alloy covered in a high-quality metal-effect plastic
The top and front plates are magnesium alloy painted with a satin silver paint that gives the impression of plastic. Nikon are trying to emulate the finish of chromed brass that was typical of cameras from the '50s to the '70s. The rear and bottom plates are plastic. The bottom plate in particular is a shame, as it feels flimsy and doesn't look quite like the top. The rear is fine, it was never going to feel 'genuine' anyway, especially with the flippy screen (which has to be made of plastic). The shell itself is amazing, made of a heavy magnesium alloy, but its plastic parts are pretty dingy.
