Kenko Extension Tube 10+16mm Set DG for MFT

With Kenko Extension Tube Set DG for Micro 4/3 mount you can conveniently turn your regular lens into a macro lens.

When attached between your lens and your camera body, it minimizes the distance from your camera and the objects you want to shoot at.

Kenko Extension Tube Set DG for Micro Four Thirds (MFT) mount comes with a set of 2 rings, in 10mm and 16mm, that can be used together for a longer focal length.

Enjoy macro photography with Kenko Extension Tube Set DG any time you want without needing a special lens.

DG EXTENSION TUBE SET (10mm & 16mm) for Micro Four Thirds mount Full Frame

Instructions

DG EXTENSION TUBE for MFT-mount Full Frame is an accessory designed for use with MFT-mount lenses to shoot at closer distance with higher magnification.
Since the magnification changes according to the focal length of the lens. you can easily make close-up shots of small subjects, insect: or flowers. Furthermore. electronic signals between the camera and lens are transferred through the electronic contacts of the Kenko DG EXTENSION TUBE for MFT-mount Full Frame , enabling you to use all of the camera's shooting modes. But depending on the shooting conditions. exposure compensation is required.

Specification

Size/Weight: Dia. 57 x l0mm / 48g
Size Weight: Dia. 57 x 16mm / 70g

Precautions

When using the extension TUBES alone (10 mm or 16 mm), or combination (10mm 16mm = 26mm), the focal length of lens should be greater than the length (10mm, 16mm or 26mm)of the TUBE/TUBES used.
Suitable lenses are from standard to telephoto as well as macro (micro) lenses. Wide-angle zoom lenses are also usable, but depending on how the lens is combined with the TUBE the distance between lens front and subject may become extremely close.

Mounting the DG EXTENSION TUBE for Micro Four Thirds Mount (MFT)

1. Mount the TUBE onto the lens first. Align the TUBE's dot (for the lens) with the lens's dot. Then turn the TUBE clockwise until it stops with a click. Be sure to keep the electronic contacts clean to ensure proper connection.
2. Mount this combination to camera body in the same way as mounting the lens on the camera.
3. When using 1 or 2 TUBES in combination, they can be combined freely.
4. To dismount the TUBE and lens from the camera, hold in the lens release button on the camera and turn the TUBE counterclockwise.
5. To dismount the lens from the TUBE, depress the release button on the TUBE and turn the lens counterclockwise.

OTHER PRECAUTIONS

• (1) In close-up shooting, as the subject's depth of field becomes shallow, never forget to stop down the lens.
• (2) Take care that when image magnification ratio increases camera shake is also liable to increase. (The use of tripod is advisable.)

IMAGE MAGNIFICATION RATIOS AND EXPOSURE FACTORS (50mm Standard Lens)

Extension Tube	Distance Reading of Master Lens	Image Magnification Ratio	Field Coverage (cm) (in case of APS-C)	Exposure Factor
10 mm	inf	0.2	6.5 x 8.7	1.44
	0,5	0.31	4,2 x 5.6	1.72
16mm	inf	0.32	4.1 x 5.4	1.74
	0,5	0.43	3.0 x 4.0	2.04
10 + 16 mm	inf	0.52	2.5 x 3.3	2.31
	0,5	0.63	2.1 x 2.7	2.66

• The above table shows general values for 50mm standard lenses. Even with standard lenses individual lenses may have actual values slightly different from these.
• Image Magnification Ratio is the ratio in size (lengths) between the subject and the image formed on the film surface. For example, Image Magnification Ratio 0.24X means that a 1 cm subject becomes 1 x 0.24 = 0.24 or makes a picture of 0.24 cm size on the film surface.
• When using an extension tube of same length, the image magnification ratio becomes smaller as the focal length of master lens becomes longer and the larger as the focal length becomes shorter. Also, the distance to the subject becomes further away as the focal length of master lens becomes longer and closer when it becomes shorter.
• For other than standard lenses calculate according to the following formulas:

Image Magnification Ratio = (Lenght of Ex-Tube + Master Lense Advance Volume) / Mater Lens Focal Length

Exposure Factor = (1+ Image Magnification Ratio)²

Mater Lens Advance Volume = (Master Lens Focal Lenght)² / (Mater Lens Distance Reading - Mater Lens Focal Length)

Field Coverage = Image Size on Film Surface / Image Magnification Ratio
