Macro lenses can get really expensive, especially if you’re just using them for hobby shooting. A rather inexpensive alternative to purchasing more glass are Macro extension tubes. These tubes move the lens farther from camera sensor. The farther away the lens is, the closer the minimum focal distance and the greater the magnification. This metal extension tube kit does not affect image quality as there are no optics inside. You can see how it changed the basic stock Panasonic 14-42mm Lens into a super macro lens.
There are no electrical contacts in the extension tubes so exposure has to be adjusted manually. Aperture control is not available if you use an electronic lens. The lens will default to it’s widest aperture. This works well with the Panasonic 14-42mm because we can default it to a max aperture value of F/5.6 and have more in focus than a lens that would default to say F/1.2. (Yes you can adapt manual lenses with aperture controls on the lens if needed). When shooting at high magnification macro or zoom, you should use a tripod and also a remote shutter release to prevent camera movement when forcefully pressing the shutter button. Another way to get sharp images is to just use the built in Timer feature. To focus with Macro you would move the camera closer or further from the object. We mounted our camera on an adjustable macro rail system which is geared to move the camera forward or backwards very minutely for easier focusing.
This extension tube consists of 5 parts: Camera Body Mount Adapter, Lens Mount Adapter, 9mm tube (Tube 1), 16mm tube (Tube 2), 30mm tube (Tube 3). You can use the camera mount coupling adapter and lens mount coupling adapter alone or combine of any or use all three extension tubes for extreme Macro photography. Since no other optical components have been added, the image preserves the original optical property of the lens. These tubes can be fitted to any lens and any camera so long as you purchase the correct extension tubes or optional adapters for your gear.
