Hi all I have the 60mm Macro, which is amazing but I am not using it that much - only once in a while do I want to get that close. The rest of the time i get close enough with the 12-40mm. My main subjects are not macro but I do like to get up close occasionally. I don't like having unused equipment lying around so was wondering should i get a close up lens instead to add on to my 12-40 to get that bit more magnification when i need it? What would the disadvantages be with this? Would I lose quality and how will it effect DOF? Sorry if these are obvious questions! Thanks in advance.
