R8 With RF-50 1.8 Auto Focus Inoperative In Manual Modes

[elmo]

I have a new R8 and when I first installed a new RF-50, the AF wasn't working in any Manual camera modes. Only MF is displayed when I tried switching focus modes. But the AF was working fine when I switched to Auto mode or in to Video mode. I rechecked AF with my other lenses and they all worked fine in all modes. I did a camera reset and AF started working in any Manual modes. But when I made any changes to the camera settings like dial functions, AF stops working on the RF-50 again in any Manual modes. There doesn't seem to be firmware updates for either the lens or the R8 at this time.

Is there and AF/MF switch on the front of the camera body?

[elmo]

No, there's a Focus/Control switch for the ring on the lens. It doesn't matter which position it is in until I performed a camera reset.

[elmo]

Sorry, the switch is on the lens.

[deebatman316]

For lenses WITHOUT an AF/MF on them. The focus mode must be changed via the camera menu. Not lens itself. 

[elmo]

Oh, I mentioned it in the OP. When AF is not working, only MF is the option.

Reset the camera and custom functions back to factory default.

[elmo]

Yes, that's what I did. But if I make changes to settings, AF is inop again until I reset. But none of the other RF lenses have any issues.

[deebatman316]

Do those lenses have an AF/MF switch on them.

[elmo]

The RF 100-400 has an AF/MF switch. The RF 24-50 has an AF/Control/MF switch.
