Manual focus not functional when zoomed out

[Ron Pestes]

This may sound obvious but are you sure your depth of field isn’t so deep that you can’t see a change? When the lens is wide it is hard to see any change in focus because everything is in focus from close to far if you have good light.

Thanks Ron.

Ya I thought about that but even when I’m 10, 5 or even 2 feet away from the subject turning the focus ring has no effect on focus. In fact it seems to be auto focussing.

I should be able to take a subject in and out of focus at mid to close range when in full manual right?

Make sure you don’t have the FULL AUTO button pressed.

Good Luck

There is a possibility that you might have a problem with the back flange adjustment. Here are some instructions on how to adjust that;

Try doing a focus adjustment from the menu. On the Ex-1 this is hidden in the maintenance menu, which you can access by pressing menu/set/cancel simultaneously. This will open the regular menu with 2 new categories, ‘Maintenance’ and ‘Information.’ Under ‘Maintenance’ you’ll see “Auto FB Adjust.” This is the flange-back adjustment for the backfocus. Put the camera on a tripod, in a well lit room 3-5 meters from the wall and run this.

You will want to use a test pattern and MAKE SURE to do this indoors, under constant light.

Here is a link to some test patterns;

It’s been recommended to use the “star” pattern.

If this doesn’t fix it, then you are in for a visit to the mothership. Good Luck.

Thanks for the feedback Michael and Marvin.

Auto\manual focus slider is in the Manual position. Ring pulled back. Is there another auto setting I’m missing?

Under ‘Maintenance’ you’ll see “Auto FB Adjust.”

I removed and reinstalled the lense and did the FB adjust twice per the Vortex field manual. Is there another flange adjustment on my EX3?

I should be able to take a subject in and out of focus at 2 to 10 feet away when in full manual right?

It depends on your F stop.

At F1.9 yes you should be able too. But at F8 or more probably not.

Are you using ND’s to keep aperture open?

Did you follow Michael Palmer’s suggestion and re check the ‘full auto’ button? This overrides all other focus, aperture settings.

Yep checked that too.

Dropped it off at the Sony service center this afternoon.
