AF Chip "Dandelion" for Canon EOS. Origin EMF chip. SAMYANG (ROKINOR) VERSION

Description

Programmable Chip of
4 Generation
Original AF chip "Dandelion"
by Victor Lushnikov
Made in Europe
One of the problems of using manual focus lenses on Canon EOS bodies is that focus confirmation is disabled. When AF lenses are used - even in manual focus mode - all Canon EOS bodies confirm focus with a green dot in the viewfinder and an (optional) audible beep.
However when non-EF compatible lenses are used via an adapter, the focus conformation is disabled. Canon didn't have to do this, but they chose to. Unless the camera thinks that an EF compatible lens is attached to it, it switches off both visual and audible focus indication.
If the camera could somehow be tricked into thinking an EF lens was attached, then the focus confirmation indicators should work with any lens attached. Well, this is just what the developer of this special AF chip has done.

Evolution of AF confirmation chip
From autumn 2008 the new AF emulator chip generation 4 are produced. Externally the new AF emulator chip looks exactly like the previous version, but internally it’s completely revamped. As from Spring 2009, this emulator chip has improvement to the quality of metal contacts (i.e. the gold plated contacts are much more shiny and therefore quality of contact to the camera pins are better!)
The new version has the
programming option
, that is, you can change AF emulator chip’s aperture and focal length settings without removing it from the camera. In addition, the new AF emulator chip has
calibration function
that makes focus confirmation more accurate.
The new AF emulator
chip doesn't use the MF mode (at default setting) because now focusing works with AF (autofocus) mode. Firstly, this improves focusing accuracy. Secondly, this enables the user to calibrate AF emulator chip for different kinds of lenses. Thirdly, the AF confirmation beep is now available for all cameras (e.g., for film camera EOS 3000N). Focusing sensor is much more sensitive in this mode.
Another new feature is the "hard" blocking of shutter release until you get the confirmation signal. If you hold the shutter release when fully depressed, the shot will be taken immediately when you get the AF confirmation signal. This allows taking fast-moving subjects.
Lastly, the most important advantage of this new version is the ability to change settings of AF emulator chip using the Camera itself. See programming instructions.
This AF emulator chip is suitable for all
Canon EOS
digital and film cameras.

Comparing original AF Chip with China chips
AF Chip "Dandelion" was developed by Victor Lushnikov in 2005. But after some time guys from china made a copy from chip of first generation. (Like they make copies of iPhone or Nokia phones).Sure these copy is chipper, but it still not original!
