Our Take

Best for: Photographers with Canon EF lenses moving to an RF body.

The SIRUI EF-RF Adapter is a solid, no-frills mechanical adapter for using Canon EF-mount lenses on Canon RF cameras. Its aluminum alloy body is lightweight yet durable, and the built-in 1/4-inch tripod mount helps stabilize heavier lenses. The red dot alignment makes attaching lenses quick. Since it lacks electronic contacts, you'll need to focus manually and control aperture via the lens ring if available. It works with any EF lens but is specifically optimized for SIRUI's Jupiter series. 44, it's a great value for photographers who already own EF glass and want to experiment with RF bodies without investing in native lenses.

Price Analysis

At $55.44, this adapter is 44% off its original $98.30. It's currently below both the 90-day average of $71.86 and the 180-day average of $60.92, making it one of the best prices observed.
