Limitations • No autofocus support for JVC and Olympus• AFC (continuous AF) and AFF (flexible AF) modes are not supported• No 24p video AF• Video AF may hunt more than a native lens• No support for in-camera correction such as peripheral shading, CA and distortion 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). They are pleased to report that Panasonic Micro Four Thirds camera bodies are capable of autofocusing fast (large maximum aperture) lenses accurately. Although Metabones first and foremost priority is accuracy, they 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 their E-mount offerings on Sony cameras prior to Alpha 7R II.Autofocus Lens Compatibility List Accurate • Canon EF-S17-55mm f/2.8 IS USM• Canon EF-S18-55mm f/3.5-5.6 IS II• Canon EF20-35mm f/3.5-4.5 USM• Canon EF24-105mm f/4L IS USM• Canon EF35-80mm f/4-5.6• Canon EF40mm f/2.8 STM• Canon EF50mm f/1.2L USM• Canon EF50mm f/1.4 USM• Canon EF70-200mm f/2.8L IS II USM• Canon EF70-300mm f/4-5.6L IS USM• Canon EF85mm f/1.2L II USM• Canon EF100mm f/2.8 USM macro• Sigma 18-35mm f/1.8 DC Art• Sigma 18-125mm f/3.8-5.6 DC HSM• Tamron SP 24-70mm f/2.8 Di VC USD A007• Tamron SP 70-200mm f/2.8 Di VC USD A009• Tokina AT-x PRO 11-16mm f/2.8 DXII Accurate only on newer cameras such as Panasonic G7 • Canon EF70-200mm f/4L USM• Canon EF135mm f/2L USM• Canon EF200mm f/2.8L II USM Inaccurate • Canon EF50mm f/1.8 II• Sigma 50mm f/1.4 Ex HSM Manual focus only • Contax N lenses modified by Conurus• Tamron SP 17-50mm f/2.8 VC B005• Zeiss ZE lenses 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.

Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, they instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of their adapters, in order to ensure smooth mounting, great appearance and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing. Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Metabones new Smart Adapter series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.• Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.• Satin surface finish - just like your OEM lens and camera mounts.• Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.• Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.• Metabones Smart Adapter series adapters have the following additional features• True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes or dial in yourself on the camera body in A or M modes.• EXIF data such as lens identification, focal length and aperture.
