If you have a DSLR or a camera with removable lenses then one does not need to go out and buy a macro lens. What I hear you say you don’t need to go out and buy a macro lens. Yes thats right. Save your money until buying a macro is really worth while.
So what do you do in the mean time, well it is simple. Take the lens off your camera and turn it around so that the front of the lens rest against the camera body. It will serve as a nice macro, most likely produce great bokeh and is cheap. Of course the down side is that one can drop the lens, dust can get into the camera body or one may touch the lens rear elements or control contacts. Which is why sooner or later one really does need to buy a specific purpose macro lens. However until that time one can make do with turning the lens around.
Just to show you what one can produce I have added in a quick shot of a flanders poppy that I took this morning using this technique. It is a bit soft but that is more from foreground objects blurring the focus area. Give it a go and see what success you have..
