If at any time you want to shoot macro but do not want to buy a special macro lens, there are several inexpensive alternative scenarios that can be used:
Install the extension tube between the lens and the camera body
Install the filter in front of the lens close-up
Reversing the lens (reverse ring)
Photo above was taken with a 50mm f/1.4 lens plus 36mm Kenko extension tube
Gradually we will discuss each of the options, but for this article we focus on the use of extension tubes. Okay on with it:
Extension tubes are mounted between the camera body and lens, thus effectively increasing the distance between the front element of the lens and the sensor field, which in turn will increase the magnification of the lens and change the minimum focusing distance.
Extension tube is a cylindrical metal ring and has no optical elements, so the image quality is not affected by the optical, but we also do not expect the quality can match the quality of the special macro lens. We can pile up some extension tubes as well as to be able get more magnification levels.
We can buy a single extension tube or buy the set, most of the extension tube length extension effective between 8 mm and 35 mm, and we can combine multiple extension tube as well, but the effect of information and electronic settings sometimes do not “connect” with the camera while we accumulate some extension tubes.
Pictured above, Left: Taken with a 85mm lens with a 12mm extension tube. Right: with a 85mm lens mounted 25mm extension tube. See the difference in magnification effect of the two different extension tube 13 mm.
The main advantage is that the extension tube enough to buy one we can use it in all the lenses. But the most ideal type of lens is a lens with a focal length range between 24 mm to 90 mm, so if you have a 18-55mm kit lens or 50mm prime lenses, they are an ideal match for the extension tube.
Canon, Nikon or other camera and lens manufacturers often produce their own extension tube, but for a cheaper option we can buy branded third party kinds of Kenko. The important thing to note is make sure that the electronic connection between the camera and the lens is still disconnected, because if it is not compatible then the sort feature autofocus or auto exposure will not work. Without electronic connections, we also can not set the aperture of the camera (and lens kit or prime lenses often do not have the lens aperture ring). So check connectivity before you pay.
For canon you can buy a Canon EF12 II and EF25 II, each of which has an extension length of 12 mm and 25 mm, or you could combine the two. If you can find an old edition is the second tube (EF12 and EF 25) under the condition that the former is much cheaper.
Nikon sells PK-11A, PK-12, PK-13 and PN-11, each of which has an extension length of 8 mm, 14 mm, 27.5 mm and 52.5 mm.
Olympus makes EX-25 for four-third cameras and 25 mm in length extensions.
If you want a cheap extension tube, you can buy a tube of brand Kenko extension tube made compatible with Canon, Nikon and Sony. In Indonesia Kenko many outstanding brands and sold a lot cheaper than you have to buy a special macro lens. So, congratulations macro shooting without having to drain the pouch.nbmnjmnmnmnmbbnmmnbnbm
