Note:

1. Requires lenses supporting distance information.
2. Autofocus disabled for Contax N and Contax 645 lenses.
3. A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
4. This Speed Booster™ is designed to cover an APS-C image circle which is not big enough to cover a full-size 36mm x 24mm sensor.
5. Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with Speed Booster™, the resulting aperture is f/0.9 but the camera body displays f/1.0.
6. Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster™ and cause damage to the Speed Booster™ and/or camera body.
7. 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 Speed Booster™. They need to be modified before they can be safely used on Speed Booster™. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed Booster™ are not covered by warranty.
8. Super-telephoto lenses such as the Leica-R Telyt 560/5.6 may have significant vignetting in the corners.
