What do you do when you want to do macro photograhy, but don't have the budget to buy a proper macro lens? You buy a cheap macro filter kit from Ebay! A kit with 4 filters cost about 12$, and is a great way of trying out some macro photograhy.
The result is of course not to be compared against using a real macro lens, but still OK for some experimenting at home.
The following is a picture I took with a Nikon D60 using a Nikkor 18-55 VR lens with a +4 and +10 macro filter mounted:
What you see here is a Musca domestica, or simply a housefly, which was sitting on the wall in my mothers house. The fly was probably meditating or something, because it was not moving that much. The picture is taken handheld using the pop-up flash, which, together with the cheap macro filters, also speak against a better quality of the picture.
