Upgraded "Gate-Array IC" circuitry to work professionally with digital SLR's and some of the digital SLR lenses, such as the Nikon DX digital-only lenses. By simply inserting between your camera and lens, the tubes create more distance between the lens and film plane to magnify your subject. No exposure compensation is required when using the camera's TTL metering system, and the tubes activate the cameras AF system properly by maintaining autofocus and TTL auto exposure with most Nikon lenses, given there is enough light (at f/5.6 or brighter).
Designed for macro photography, the extension tubes allow you to convert almost any lens into a macro lens without the expense of a new one. You can capture stunning close-ups with the professional optical quality of your original lens. This Tube Set is compatible with Nikon DSLR cameras and F mount lenses and is optimized to work with Autofocus lenses.
Keep a couple of 'em in your gig bag so you'll always ready for that breathtaking macro shot!
