  1. A third party zoom lens may need to be registered with the Speed Booster/Smart Adapter first in order to detect its maximum aperture.

  2. Some improperly-made M42 screw mount adapters may short the electronic contacts of the Smart Adapter and cause damage to the Smart Adapter and/or camera body.

  3. Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Smart Adapter. They need to be modified before they can be safely used on Smart Adapter. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Smart Adapter. Scratches and damages caused by rear protrusions on Smart Adapter are not covered by warranty.

  4. For those passive (without electronic pin or without power supply from the camcorder) MFT camcorders, this Smart Adapter can also be powered by third-party 5 Volt MicroUSB power supply*.

  • *third-party 5 Volt MicroUSB power suppliy is not provided in the box. The compability of 3rd party power supply can't be guaranteed.
