The Kenko Auto Extension Tube Set DG contains three tubes of different length - 12mm, 20mm, and 36mm - which can be used individually or in any combination to obtain the desired magnification. Actual magnification effect changes with each specific lens.

This DG Extension tube set has upgraded "Gate-Array IC" circuitry to work better with digital SLR's and some of the digital SLR lenses, like the Nikon DX (e.g. 17-55mm, 10.5mm) digital-only lenses.

Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.

The extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens farther away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.

When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters).

Enables Closer Focusing/Macro Capability    12mm, 20mm, 36mm Tubes    Works Individually or Combined    Retains Auto Focus Capability    Metal Mounts    Fits Nikon F-Mount Lenses and Cameras

The Kenko Auto Extension Tube Set DG is compatible with Nikon DSLR cameras and F-mount lenses and is optimized to work with Autofocus lenses.

Kenko's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Nikon lenses given there is enough light (at f/5.6 or brighter) to activate the cameras AF system properly.

A: The tube body is hard plastic, but the actual mount mechanism is metal. It is a good product for the price and I have not had any issues with durability or performance.

Q: 4. Do these tubes work on the Z9 with or without the adapter for Nikon F ?

A: These Extension Tubes will fit on the Nikon Z9 with the Nikon FTZ adapter. In terms of compatibility it would need to be tested since it was not designed fore this use.

Q: 5. Do they affect the image the same way as cropping the image in post processing? My macro lens has a minimal focal length 250mm, if I put on 7 of the 36mm tubes will it reduce my minimal focal length to 0?

A: No, extension tubes will maintain the resolution, unlike when you crop an image in post processing. 3 tubes will bring you to about 25mm close focus distance

Q: 6. Will this work with d3400 ? Thanks

A: My set of Kenko extension tubes works very well with my Nikon D3400. Depending on which lens I use, I sometimes prefer auto focusing and sometime prefer manual focusing.Have fun discovering which technique works best for you !

Q: 7. Are these tubes made of metal or plastic ? My thanks to you in advance.

A: The tube itself is plastic, but high quality. The coupling surface, the surface that comes in contact with your camera and lense, is metal. The complete set appears to be of very high quality and if you need extension tubes, I can recommend this set.

Q: 8. Has anyone used these extension tubes with Nikon 300 mm f 4 or 600 mm f4 VR lenses?

A: Most use extension tubes with shorter lenses. Usually lenses around 100mm or so at the most.One issue is that the focus will be critical in general and very difficult to focus with such long focal length lenses.

Q: 9. Will these work with my Nikon D60?

A: Yes, this extenstion tube set is compatible with the Nikon D60 camera.

Q: 10. Will this work with Nikon D3300?

A: Yes, they are compatible with the D3300.
