Auto+manual focus ranges on the 850Z

The auto-focus system in Kodak slide projectors is really an auto-measurement system: One set manually, the system is supposed to maintain that distance on all subsequent slides. Correct orientation of the slides is that they are all placed in the slide tray in the SAME direction (the matte side of the transparency facing toward the screen). The measurement is from the FRONT of the slide transparency to the BACK of the projection lens. REPAIR calibration of the system requires 2 special tools: a RANGE SLIDE and a TARGET SLIDE. These tool slides and the calibration procedure SHOULD be available from: www.micro-tools.com They purchased all remaining repair parts from Kodak when Kodak stopped supporting slide projectors. Good Luck !! Jim

You may have put the camera on manual focus. Two ways to do that.
1. There is a switch on the lens which allows you to select auto or manual focus. Be sure the switch is set on A or A/M. If it's on M, you are on manual focus.

2. In you menus, there might be a mode which is manual focus. Look in your manual index under Focus, manual. There might be a setting in the Focus Mode menu.

You can also try resetting your camera. This will put most things back to factory default mode, including the focus mode.

When playing around with controls, go step by step through the manual and try things out. Be sure to set the control you were playing with back to default unless you really understand that setting.

Seems possible that the servo control /main processor control is faulty and will need help from Nikon service , It will be better to get a evaluation for the fault and so we can have a consenses on the fault.
get estimate and decide.

try cleaning the lens.

Also set the focus range in the camera to average both vertically and horizontally. That is when you press the shutter button thos red squares in the look through a;; ;light up rather than just the centre square.

I suspect it is getting feedback from something on the lens that it reads and tries to focus on that is closer than the object you want to photograph. Make sure there is no mold growth inside lens as that will do it too

You can ususally find a repair manual for you vehicle at Auto Zone, O'Reilly's Auto Parts, or Advance Auto Parts, for about $20 - $25. If they don't have what you are looking for, just ask, they would probably be able to order it for you.

any auto parts store sells a chiltons manual on your ford focus!!! i think they are around $12 dollars it will explain step by step instructions..........................

Change from auto focus to manual focus or focus using only one focal square and change the setting to One Shot. You may need to shoot in Manual (M) mode though. Any of the "auto" modes will not let you.

re you sure the out of focus condition is due to the actually focus or do to motion blur? I think the 3100Z in auto and flash on will set the shutter speed fairly low like 1/30th of a second for wide angle and 1/90th for full telephoto. This may not be fast enough to avoid motion blur. I would suggest using manual mode and shutter priority and set the shutter speed to 1/100th of a second. This won't effect the flash output but will reduce the amount of ambient light being captured which could cause long range shots to become darker in the distance. Name of the game, don't be afraid to take it off auto mode and experiment with manual setting.

AF/MF (Auto Focus/Manual Focus) * The AF/MF function works in CAMERA, M.REC mode only. * In most situations, it is better to use the automatic focus feature, as it enables you to concentrate on the creative side of your recording. * Manual focusing may be necessary under certain conditions that make automatic focusing difficult and/or unreliable. Auto Focusing * If you are inexperienced in the use of camcorders, we recommend that you make use of Auto Focus. Manual Focusing In the following situations, you may obtain better results by adjusting the focus manually: * A picture containing several objects, some close to the camcorder, others further away. * A person enveloped in fog or surrounded by snow. * Very shiny or glossy surfaces like a car. * People or objects moving constantly or quickly like an athlete or a crowd. Follow These Simple Steps To Set The Manual Focus 1. Set the power switch to CAMERA mode. 2. Turn the MENU DIAL up or down until the FOCUS is highlighted and then press the ENTER button. M. FOCUS(MF) will display. 3. Turn the MENU DIAL up or down until the object is in focus. Zoom out a little if focusing is difficult. 4. To return to AF (Auto Focus: ), press the ENTER button again.
