Here is how the macro picture without macro lens.
A macro lens is too expensive. With a single lens 18-55mm, it is possible to make very nice macro picture.
He obviously need an SLR camera and a basic 18-55mm lens.
You just have to ride the upside, a fat ring inversion that easily less than 10 euros.
All setting will then manually. We must open up the diaphragm for maximum brightness.
the focal distance is very small by cons, we must bring near the subject to photograph.
With good lighting, you can do macro shots at a ratio of 3: 1, which is excelent in macro.
Here is the diagram of the assembly, and some of my macro picture.
Good shot at you
