Products Instructions:
-The Auto Extension Tube Set for Micro 4/3 (Micro Four Thirds) Lenses is a set of two extension tubes for mirrorless interchangeable lens cameras. This set has tubes of 10mm and 16mm. The tubes can be used individually (10mm, 16mm) or in combination (10mm+16mm) to botain the desired magnification.
-Extension tubes are hollow cylinders without optics designed to enable a camera's lens to focus closer than its minimum focusing distance and therefore provide more magnification. They are placed between the lens and body and are particularly. They offer increased magnification for whatever need.
-An extension tube increases lens magnification by an mount equal to the extension distance divided by the lens focal length. For exmple, adding a 25mm extension tube to a 50mm lens will give a magnification gain of 0.5X. Therefore, if the lens's original magnification was 0.15X. then the new magnification will be 0.15X + 0.5X =0.65X.
-This Auto Focus Extension Tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with Micro 4/3 (Micro Four Thirds) lenses. Compatible with Panasonic Lumix GH3 G5 GF5 GX1GK GF3GK G3 G2 GF2GK G1 GF1 G10
Kindly Note:
1)When using extension tubes the lens will not focus to infinity. The focus range will be greatly limited to a very close focusing distance.
2)There is light fall off when using any extension tube, Sometimes the equivalent of 3 f-stops of light is lost when using multiple extension tubes together. This light lost can affect the camera's ability to auto focus. Manual focusing is recommended should the lens begin to "hunt" (not lock onto the subject).
