There are standalone chip makers who provide standalone chips. Just attach it with any lens and these chips start acting as CPU for that lens. feature are
1. AF confirmation beep.
2. EXIF data
but chip i am using also provides
3. Trap focus (As when camera achieves autofocus it automatically fires shutter)
If anybody can help in software like linking ML and any of these chips, an external motorized focusing rig for all these manual focus lenses can be done. This rig will make all manual focus lenses autofocusing mechanically....aperture controls can also be done.
