Canon EF Lens to Micro Four Thirds Speed Booster S lisää EF objektiiviin aukonsäädön kamerasta. Firmware päivitettävä.
|Features and Benefits|| |
Autofocus with an Optimum Balance of Accuracy, Speed, Consistency and Reliability
Starting from firmware V1.7, autofocus is enabled on Panasonic camera bodies, subject to certain limitations (see table below for details). We are pleased to report that Panasonic Micro Four Thirds camera bodies are capable of autofocusing fast (large maximum aperture) lenses accurately. Although our first and foremost priority is accuracy, we are able to make great strides in autofocus speed as well, which is significantly faster than a DSLR Four Thirds lens on a Panasonic Micro Four Thirds camera (with adapter), or our E-mount offerings on Sony cameras prior to Alpha 7R II.

Manual Focus Lens Compatibility
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.
Focus confirmation “chips” such as Dandelion are incompatible.
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 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.
List of manual focus lenses which REQUIRE MODIFICATION to be used on Smart Adapter

Elmarit R 35/2.8
Summicron R 50/2
Every Pentax K-mount lens has a protruding fin and an aperture lever. It does NOT fit.
