AF “Dandelion” Chip for Canon EOS, 4th generation, programmable

This is the latest (4th) generation of this chip. Genuine product from inventor, not a cheap copy.

Narrow, slim (3.4mm thickness), corrosion-resistant contacts. It can be programmed from the Canon camera.

Delivery set included the chip itself, installation guiding bracket, optional support pieces for narrow mounts.

Specifications:

• Aperture – From F1.0 to F64
• Focal length – From 1 mm to 65535 mm
• Correction of focus confirmation dot (calibration of front / back focusing) – 17 levels
• Focus mode – AF / MF
• Entering program mode – Delay from 1 sec to 99 sec (with each step of 1 sec)

The new version has the programming option, that is, you can change AF emulator chips 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.

This AF emulator chip is suitable for all Canon EOS digital and film cameras.
