Third party affordable lens maker Yongnuo’s finally making lens for Nikon DSLRs, few months ago the Yongnuo announced 50mm F1.8 lens @ $50, but the problem for Canon 50mm F1.8 lens contact mount t is also made up plastic.
Yongnuo improved the mount material of 50mm for Nikon and now they added metal mount instead of plastic mount.
