If you already own a lot of Canon lenses, switching systems “just because” usually isn’t the best value. Your lenses are a major investment, and adapting them to Sony can be inconsistent: some lenses work well, while others—especially older or third-party designs—may have autofocus or compatibility issues.

Adapters can make sense as a temporary bridge or if you only need a few specific Canon lenses that are known to behave well on Sony. But if you rely on a wide range of lenses, you may run into a wide range of issues.

Sony bodies do have real strengths, and some photographers find features like the autofocus system genuinely helpful. But don’t base a system change on hype alone.

The most practical advice is to rent a Sony body and adapter for a weekend and test your own lenses in your own shooting scenarios. That small cost can save you from an expensive mistake.

If mirrorless is the goal, it may also be worth staying in the Canon ecosystem and waiting for or moving into Canon’s mirrorless system as it matures, especially if keeping strong lens compatibility matters to you.
