Just wondering if anyone has used close up filters in combination with a dedicated macro lens.
Yes I understand there will be some reduction in image quality, but I am thinking it would be a easy way of obtaining greater than 1:1 without using extension tubes (which I don't really like!), plus the lens is extremely sharp to start with.

Current lens is a Vivitar series 1 105mm macro, and thinking about getting a set of Hoya filters (+1,+2,+4)

Any information appreciated.

Cheers,

Matt
