PRONTO Mk2 Autofocus Adapter Manual/Firmware– Leica M Lens to Sony E-Mount CamerasUpdated 2 years ago

Adapter Firmware Updates

Ver .03

2021/03/31

• Recalibrated focusing to accommodate smaller, lighter lenses and improve speed
• Manual Mode can be activated. When in AF mode change the aperture value to f/29, then take one image. The helicoid in the adapter will fully retract so that proper manual focus can be used. To switch back to AF mode, change the aperture value to f/2.0 and take one image.
• Macro Manual Mode can be activated. When in AF mode, change the aperture value to f/32, then take one image. The helicoid in the adapter will fully extend, essentially creating an extension tube. To switch back to AF mode, change the aperture value to f/2.0 and take on image.
**You cannot switch from Manual to Macro or Macro to Manual directly; you much change back to AF mode first.
• A full range of aperture values has been added for two purposes: 1. To prevent accidental changes to manual mode from AF mode (previous firmware only had f/2, f/29 and f/32). 2. To provide accurate EXIF data for users that would like it; this has is NOT automated and must be set with the dials on the camera.
