Make A Zoom Lens

Detailed close-up shots can be taken with a DIY macro lens.


There are many possible ways to create a macro lens for your camera. The trick is to find the right combination of lenses in order to create one super macro lens. The created lens works best when a medium focal-length lens is attached to the camera and a fast secondary lens is held at the end of the primary lens. You will have to experiment with the lenses that you already own to see which combination works best for your camera.


Instructions


1. Attach an18 to 55 mm lens to your camera, as usual. To eliminate creating a photograph with a vignette, you will need to zoom this lens to 55 mm.


2. Turn on the camera and switch the setting to manual focus. Dial in compatible shutter speed and aperture settings and a positive exposure compensation.


3. Invert the secondary lens so that the side that usually connects to the camera is facing outward. You will have to hold this lens steadily in place while you take photographs. Because there will be an incredibly small depth of field, any movement will create the possibility of throwing off the picture completely. To focus your shots, you will have to press the shutter button halfway down and move the camera closer and further away until the subject in the frame is fully focused.


4. Place the ISO at a setting of about 800 so that you will be able to use a somewhat quicker shutter speed. You should then be able to set your shutter speed at 1/100 or higher.


5. Use a tripod to gain more stability and to decrease any chance of blur while taking your shots. While a tripod can help, holding the secondary lens in place while setting up your shots can become tiring to some people. It is more of a personal preference of how you want to set up your shot.


6. Start shooting and experiment with the settings on your camera until you find the one that works best for the lighting you are in and the subject you are shooting.
