WOW!what do you mean by an extension tube?

It is a tube that fits between the lens and the camera body - which allows much greater magnification at close focus distances (but you cannot focus any more at longer distances). Very cheap alternative to a proper macro lens.

Lovely shot, almost abstract.

I see... so can I also use an extension tube with pentax k-x and an 18-55mm lens kit for better macro shot? I'm really new to photography, any advice is very much appreciated... Thank you!

Lowela - it would be possible to do this but you will not be able to change the aperture in the lens without buying an expensive extension tube that has all the connections that allow you to do this from the camera body. You can use cheap tubes with old lenses that have their own aperture ring.

With the kit lens, your cheapest option would be to buy a close up filter to screw into the front. You can buy them off EBay in sets of three (different strengths) very cheaply, or look for brands like Kood, Hoya or Marumi for reasonably priced filters from reputable shops.
