First off....I know NOTHING about cameras.
Ok so I've been reading blah blah and I found the screw onto the end of the lens macro addition screw onto where the filter would.. Are the helpful? Would it increase photo grade? Or is it more of a outdoor look..the seller posted a picture of some piece of jewelery and then a downtown picture kinda gave it...what I would call walleye vision? Or fish look? If we knew what fish see..thoughts
