Product Name: Macro Extension Tube Ring for M39 Product Code:LC8313 Description: A macro extension tube is a wonderful substitution to expensive macro lenses. It maintains the original optical quality while transforming the lens into a macro lens. It is far more desired then the add-on close-up lenses, which will alter the optical quality. Material: Metal Color: Black Suitable For: all camera with 39mm lens How to use 1) set your lens to maximum aperture (recommend); 2) set-up camera and lens to manual mode, switch off and detach the lens; 3) attach extension tube between the camera and lens (look for red dots and align on mount collars; attach same way as lens); 4) put your camera on tripod, or better on rail system; 5) put an object very close to the lens and use lot of light (1-3 flashguns, or 3x 500w lamps, or at least 1 strobe-light, or take pictures outside in bright sun); 6) if the photos is underexposed, please increase ISO and decrease shutter speed; 7) focus by moving camera further or closer (if on rail system), or use manual focus ring on lens mm by mm (very slow) until object in focus. If you use all set of tubes together, the focusing object usually need to be no more than 1 or few cm from the lens! Please remember that DOF (depth of field) is very small. You don't need to use all tubes together - you can combine tubes - shorter length you use, in viewfinder becomes lighter, but again not as high magnification as with all tubes together.
