What it goes on
Metabones EF-E Smart Adapter · Sigma MC-11. Iris control and IS work; autofocus works on most lenses but is slower than native, and continuous video AF is hit-and-miss.
Canon Mount Adapter EF-EOS R · Canon Drop-In Filter Adapter (VND). Canon's own adapter: EF lenses behave natively, and the drop-in version adds a variable ND behind the lens.
Sigma MC-21. Iris and single-shot AF work; no continuous AF in video.

Metabones EF-MFT Smart Adapter · Viltrox EF-M1. Iris control works; AF is slow. Remember the 2x crop — or use a Speed Booster.
Fringer EF-NZ · Techart TZC-01. Third-party electronic adapters — iris and AF work with most lenses, firmware dependent.
