Canon EF to RF adapter watch before buying . EF to RF adapter .Canon EF lenses can be used on their new mirror less RF cameras is great …Except for one issue that no one else is talking about . The adapter can cause the batteries to Drain FAST on their new RF mount cameras when using an older EF style lense with the adapter . I tried 3 different adapters and all but 1 drained the battery overnight .
I hope this video helps some folks who may be experiencing the same issues . I know , I know , I’m not a camera or lense reviewer but nobody else even mentioned this potential problem . It’s not a deal breaker . But it’s worth noting I think . Thanks for Watching
