Common Issues and Resolutions

Auto-Magnify works only with some of my lenses

Note that auto-magnify requires a lens which transmits distance information to work.

I cannot turn-off Auto-Magnify!

Problem: I want to use Focus Peaking alone without Auto-Magnify getting in my way. If MF Assist is turned off using the camera's Setup menu, it cannot be activated altogether. What I want is to activate MF Assist only when I manually press a button.

Resolution: see “Focus Peaking” section in the Metabones Smart Adapter/Speed Booster Operation Manual. In a nutshell, there are 2 possible solutions.

  1. MF Assist and Focus Peaking are turned on in Setup Menu, camera body set to MF in Camera menu, and AF/MF switch of lens set to AF (only possible with lenses supporting full-time manual focus), or

  2. configure the Metabones Smart Adapter in Green Mode.

Image Stabilization remains activated even when I am just browsing the camera's Setup menu.

Resolution: put the Metabones Smart Adapter in Green Mode.

Incorrect Maximum Aperture is displayed on the camera

Resolution: some third-party zoom lenses require registration with the Metabones Smart Adapter before their maximum aperture will be displayed correctly. See “Lens Registration” section in the Metabones Smart Adapter/Speed Booster Operation Manual.
