Noob question I can't believe I'm even asking

but I'm having a brain float and can't figure it out! I apologize in advance.

I want to be able to manually set my ISO, f stop and shutter speed, but I want to have the lens autofocus. How do I do that with my 50D? (I know - stupid question!) TV and AV settings only let me control one or the other, manual won't autofocus.

I want to try autofocus for lunar shots, because I'm blind and can't get manual focus quite sharp enough. And I want to check my lenses autofucus using a chart, so need to control the other settings.

Help, please!

have u checked the lens itself? it should be in the AF position.

If you have the AF turned on on your lens, your camera should still autofocus in Manual mode.

Duh! See, I told you I was having a brain float! Thanks.

Also, to get full control on the 50D for some things, you have to have the On switch in the full on position.

Good luck

This forum is great when suffering from brain floats.

I wondered when someone would make a joke at the OP's expense

Hey man, we all have to start somewhere. Learning what buttons do what on your camera is one step in the process, no less important than learning about aperture and the like. This forum is here when you need it! Good luck.

It's not a joke. The switch has three positions: "off"; "on"; and "fully on." As was said, it must be fully on for certain functions to work properly, specifically, those functions associated with the control wheel on the back of the camera.

That reminds me of the time last week when I complained that I couldn't change the EC on my friend's 40D. I had forgotten to make sure that the wheel was turned on.

lol, we all go through it, some more than others

Well I'll be damned. We learn something new everyday

It helps to read the manual, too.
