Make sure you have not set a dial control to say manual focus or Macro focus. Run through the menu's on the screen to see if you have inadvertantly changed sometihg. As you are computing - give Pentax Technical Support Team a a go on their website

Auto Focus won't work

Another cause of auto focus failure is the circuit connecting the moving parts inside the lens. These "Flexi circuits" move with the lens components and wear out after a while. They are cheap enough to find on ebay and easy to replace.

Hello, while vacationing in Hawaii I my camera would not auto focus. I was using my 18-135 lens. It will go in and out of focus rapidly but never stop to focus. Upon my return home I tried another lens...

I do not think your lens is out of order.
Sometimes this happens.
If your lens is not out of order then lets think the problem is another thing according to the user.
Autofocusing is great but under some conditions such as below you may consider.
Shooting in dimly lit environments can be difficult for some cameras and lenses when it comes to focusing.
You’ll know when your camera is struggling in Auto mode when every time you go to take a shot the lens will whirl from one end of it’s focusing options to the other and back again before deciding on where to focus.
This can really lengthen your shooting process and make taking quick candid shots quite frustrating.
Switch to manual mode and you can quickly find your focusing point and get the shot you’re after.

Shutter frame rate drops to about 1 per sec on CH with MB D10 while using any auto focus lens. 14-24,24-70 or 70-200 and an older 20mm auto focus. With no lens or a manual focus, very old 55mm Micro, lens...

Wow, that's weird. Does it do it with the auto-focus switch on the body turned to manual? I shoot a D300 and know pretty much everything about it there is to know and the D700 is basically the same camera with a full frame sensor. The only things I know of that drop CH frame rate are shooting in 16-bit raw and it shouldn't kill it like that, using full-auto with tracking will also cause a lag in auto-focus but that still doesn't seem right here. If it only does it with the auto focus on then it may have trash on the AF screen in the camera and needs to be cleaned. Try setting the body switch to manual focus, remove the grip and shoot jpeg and see if it still happens. If it does, reset the menu settings and try again. If it still does it than you probably need to give it a trip to Nikon. If it quits than start putting things back one at a time until you figure out what is doing it.
Somebody told me that Nikon will clean the pro cameras for free once a year while under warranty, I haven't looked into it yet to make sure.

Canon Rebel xti - auto focus problem

AI should be focusing. You really can't change many settings when you are shooting in auto mode. Is the lens in AF mode?

I'm sure you have long since returned from vacation!

Hope this helps!

Auto focus not working properly

I have the same problem with my camera. What did you do about your autofocus mess?

Focus Problem

Low light focus lock can be a problem with this camera. But in normal or bright light there should be no problem with auto focus lock. If this is a new problem, you should check to see if a setting has been changed. With so many options, it is easy to accidently set something that causes unusual results (been there, done that). First ... Go to the Setup Menu and see that the "All Reset" option is selected. This will cause everything to be reset to factory default each time you power-on the camera. Turn the camera off and then turn the camera on. Then take some test photos to see if your auto-focus-lock is improved. If that works, there is no need to check the items below. If that does not work, here are some control changes to try. Remember if you turn off the camera everything gets reset. That camera uses contrast detection for auto focus and it is normally set to "Multi-Area Auto Focus". Try changing it to "Spot Auto Focus" and do some tests, including with the camera set to one of the programs or manual mode. There is another setting called "Autofocus Area", you should investigate. Check your manual to determine what you can do with this control. There is another control called something like "continuous auto focus". Check the manual for further information. If none of the above help, it is time to see about some camera repairs.
