Does anyone know what are the advantages of a macro lens over a macro filter (e.g. X6, X7, X10)? I heard that an actual macro lens is supposed to give better quality than a simple macro filter but since I haven't tried both, I am not so convinced.
Also, I have seen very good pics taken with a macro filter so I am wondering why people would still want to buy an expensive macro lens. Apologies for the ignorant question but any thoughts on this are welcome.
