AF "Dandelion" Chip for Nikon F, programmable

Purpose and Features

The Dandelion is designed to be installed on adapter rings and manual lenses so that they could then be used on Nikon AF digital and film cameras.

Thanks to it small size, it can be fitted to any existing adapter ring or lens with Nikon F bayonet mount. Lenses with such bayonet mounts have been produced since 1959.

With the Dandelion fixed on the ring, a camera obtains exposure metering function. If your camera has a 3D matrix meter, it will function as well.

Precision focus will be acknowledged by a sound and light signal. You will also find highlighted spots on the screen, that got into focus area. Entry level digital cameras will provide a confirmation beep.

With the Dandelion installed on a lens with an automatic AI-S aperture, the aperture will be controlled through the camera similar to autofocus lenses. This is one of Nikon's strongest points: you don't have to care about the aperture when using an old manual lens.

The Dandelion has another peculiar feature of "hard" shutter block before the confirmation signal. When pressing the shutter release button down to the stop, the shot is made immediately in response to the signal. This is useful when shooting fast-moving objects.

The Dandelion's most important feature for eager photographers is the possibility to change its parameters without taking it off the camera. You can alter focal length and other parameters pre-set in the Dandelion. See programming instructions.

Dandelion is compatible with the most digital and film Nikon AF cameras.
