Meike Extension Tube Set Eco Nikon
The Meike Extension Tube Set consists of three extension tubes that significantly improve the macro capabilities of your lenses without sacrificing quality. When using the metering system, no exposure compensation is needed. Also the auto focus will still work, when using the new AF drive.
Ideal for macro photography
This three part intermediary ring set makes the small world big. A spacer ring is placed between your lens and the camera. This allows you to get closer to the subject and makes the subject appear larger on the photo. A spacer ring is hollow, so it does not contain a lens system. It does not change the quality of your lens. Intermediate rings work best with telephoto lenses. All automatic functions of your camera are maintained. The set consists of three separate parts that can be used independently or together. The more rings you have, the closer you can get to your subject.
How does an intermediary ring work?
A spacer ring increases the distance between the image sensor of the camera and the rear lens of the camera objective. This shortens the focusing distance of the lens, making it possible to focus closer on the subject. As a result, the subject is projected onto the sensor larger than it would be without a spacer ring. A spacer ring therefore increases the magnification factor of a lens. This can be calculated using the following formula.
Please note
Please note that when using all 3 stacked spacer rings there is a loss of light of approximately 2 stops! ,

Maximum magnification with a spacer ring = lens magnification factor + (mm spacer ring / focal length)
Suppose you have an 85mm lens with a magnification factor of 0.13. With the 12mm ring the magnification of the lens becomes as follows.
Maximum magnification with 12mm ring = 0.13 + (12 / 85) = 0.13 + 0.14 = 0.27
With the 20mm ring, the magnification of the lens becomes as follows.
Maximum magnification with 20mm ring = 0.13 + (20 / 85) = 0.13 + 0.24 = 0.37
With the 36mm ring, the magnification of the lens becomes as follows.
Maximum magnification with 36mm intermediate ring = 0.13 + (36 / 85) = 0.13 + 0.42 = 0.55
You can also combine the spacer rings, with all three spacer rings the magnification factor of the lens becomes as follows.
Maximum magnification with 68mm spacer ring = 0.13 + (68 / 85) = 0.13 + 0.80 = 0.93
