Greetings,

Please tell us the exact model of the lens you are using? If you are using an adapter, we'll need the brand and model of it as well.

The error message you're receiving has to do with a function that can't be completed. We're happy to investigate this further with you, If you want to tell us the shooting mode you are using, etc.

However, it might just be easier for you to reset the camera's settings to defaults and retest. This should rule out a software or settings issue (user error) vs a hardware (lens, accessory or memory card) problem.

Yes to full reset. First thing.

What "800mm" lens?
