Mum bought me this but i could not figure out how to use it. she bought it used, but i myself have not used it. i’m new to cameras and photography, and she bought me the wrong lens, which is too difficult for me to use. good quality and contains two lens caps, and a 2x adaptor. i will ship the instructions the seller gave with the lens, but i do not know anything about this lens, how to mount it or how to use it.
