DANDELION IV: Programmable AF confirm chip

There are a lot of great old world lenses out there but unfortunately you would not get auto focus and other information to work as there is no way for the modern camera to communicate with such "dumb" lenses. That is unless you use an AF confirm chip. Suddenly you get a wider range of glass available to you and at a more affordable price too. Enter the Dandelion IV, that works on modern digital camera bodies from Canon, Nikon and even the M4/3 brands like Panasonic and Olympus with the use of adapters.

Today's 4th generation Dandelion chip consists of an integrated circuit connected to a series of exposed electrical contacts, in a curved package which matches the lens mount. It is designed to be affixed in a particular position on the mount, in order to mate with matching contacts on the camera body. The contacts on both sides of the mount are commonly known as CPU contacts. Camera functions enabled by the chip may include exposure metering, aperture display and control, focus confirmation and fine-tuning and Exif metadata recording. In addition, the new AF emulator chip has calibration function that makes focus confirmation more accurate. Lastly, the most important advantage of this new version is the ability to change settings of AF emulator chip using the Camera itself.

Another benefit,; you can glue it to your existing camera adapters without having to purchase a new adapter. The product includes the IC chip, the back support plastic, and an alignment template.
