Metabones’ Upgraded EF-MFT Adapters

Adapter maker Metabones has announced a new feature called TruePDAF Technology, which the company says improves autofocus and image stabilisation performance when adapting Canon EF lenses to Micro Four Thirds cameras. The update is arriving for the company’s newer Speed Booster Mark II and Smart Adapter Mark II products and is essentially a firmware-based upgrade that takes advantage of newer hardware inside the updated adapters.

TruePDAF works by using additional lens profile data from more than 100 supported EF lenses and sending more detailed metadata directly to the camera body. According to Metabones, compatible lenses can transmit information similar to what native lenses already provide, allowing cameras to make better autofocus calculations. The company says improvements are most noticeable in more difficult situations, including low light, low-contrast scenes, autofocus near the edges of the frame, and focusing close to minimum focus distance. Compatible lenses can be identified through the adapter itself, supported combinations cause the adapter LED to glow pink instead of white.

There are still quite a few limitations, though. Metabones says the best results currently require either the Panasonic GH7or Panasonic G9 II, noting that other cameras will not achieve the same near-native performance. The company later added that cameras like the Olympus E-M1 and OM-1 series still show improvements, although results appear less consistent. The supported lens list is fairly broad and includes both full-frame and APS-C EF lenses from Canon, along with third-party lenses from Sigma, Tamron, and Samyang. The new Metabones EF-MFT Mark II adapters start at $399.
