HELP!! AF wont work on either lens

Hi there.... I hope someone can help me... I hope my camera is not broken. I was trying to shoot my girls for Christmas today and my 50 1.8 would not auto focus... I thought maybe it was the lens motor not working.... but then I put my Tamron on and the same thing happens.

I do have the lens switched to AF.... I can manual focus and take pictures. I have a photoshoot later today and it's going to be no fun if I have to manual focus everything.....

Is it a camera problem, or maybe there is a setting I can check?? I removed and replaced the battery, but no change.

maybe you have activated custum function cf4??? than the ae lock button will function as AF lock.

just a guess.

I would have ventured this guess too given that both your lenses do not work... If not, you might have to live with MF till the holidays are over

Cheers!

Okay that makes sense since I just discovered that the AF works in the full manual modes. Now Keep in mind that I am still learning to use the camera and do not know for sure what all these things mean.

What setting should I set cf4 at to be make the af work?

Okay.... WOO HOO!! I'm all clear! THANK YOU, THANK YOU, THANK YOU!! I changed the cf4 setting to zero and waaa-lah-ah Focus happens! I was so afraid there was something wrong with my camera.... I wonder how it got changed in the first place.

Now that this is done, can either of you direct me towards a manual that will be more helpful than the less-than-helpful one that came with my camera?

Thanks again.....I could just kiss both of you!

if you know you haven't set any Custom Functions, you should have a menu choice that allows you to reset them all. That will undo any CF that may have been inadvertently set.

Good luck. I don't think you have broken camera.

Damn, why am I always late?!

Glad it worked out for you.

Okie dokie!! Thanks again.... As I am learning the only cf I have set is the fill flash in a/v mode to 250.... I'm not sure what exactly that means, but it is supposed to decrease the amount of flash, I think.

That happened to my 50 1.8, but I just took the lens off and put it back on. It still happens sometimes.

Yeah, I was reading that it happens to the 50 1.8 which is what I was using at the time, that's why I put my Tamron on. I was glad to know it was just the custom function problem.

glad i could help

That won't affect the flash at all. But it will keep the Av shutter speed at 1/250 sec. when you use the flash. The default setting lets the shutter speed vary so the background gets a proper exposure, but that can be too slow for hand-holdability.
