I’ve recently made the jump to a Canon EOS R6, but I’m still holding onto a few of my favorite Sigma Art and Tamron G2 lenses. I’m torn on which EF to RF adapter to pick up. While the official Canon ones are the obvious choice, I’ve heard conflicting reports about how well third-party glass handles autofocus speed and eye-tracking through them. Some users mention firmware glitches with brands like Viltrox or Meike, while others say they work perfectly. I’m really looking for stability without breaking the bank. Has anyone here tested third-party lenses specifically? Which adapter has given you the most seamless, native-like performance for non-Canon glass?
