Kooka KK-N68 Extension tube set
The Kooka KK-N68 Extension tube set was designed for macro photography with both Nikon SLR cameras and Nikon F-mount lenses. The set enables you to focus much closer to small objects, so your subject will be bigger on your photo. All the capabilities of your camera and lens, such as autofocus and light metering, remain available.
The set consists of 3 extension tubes of 12 mm, 20 mm and 36 mm. They can be used both individually and together. The extension tubes are made of chromium and of course there is no loss in image quality because they contain no optical elements.
The extension tubes come with lens caps to prevent dust from eventually entering your camera or lens.
