When the Camera Is In Manual Mode, It will not Change Focus... I spin the wheel and nothing happens. Also i have just discovered in this mode, if i take a photo without the flash on, it will come out...


I don't know about your camera, but when mine is in manual mode, it allows me to set the aperture and shutter speed but does not affect the autofocus. To make the focus manual, I have to move a switch next to the lens. When in manual mode, are you setting the aperture and shutter and what are you using to determine correct exposure?

I have a vivitar vivicam t027 and there is a slidding button on the side with a flower and I don't know how to describe it maybe a triangle. What does that switch do?


That's the macro switch. In the flower position the camera only focus on subjects close to the lens. This lets you take pictures of flowers and insects, for example. The other symbol is a mountain and in this position the camera focus on objects farther away. You want to use this setting for most subjects, like people and scenery.

You cannot use the flash in macro mode. It's all described on page 12 of the manual. If you need a manual, you can download one from the manufacturer's web site at

Hi Ref: Digital Camera - Pentax K200 model It keeps auto focusing when in manual mode. Regards Chris


Putting the camera in manual mode still doesn't change the focus routine. If you want manual focus, there is a switch near the lens on the left allowing AF (auto focus) and MF(manual focus).

All the pictures are blurry the auto focus isn't working


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.

Hi I bought my canon 1000d on september 2009 and a year later the autofocus doesnt want to work. In the viewfinder on the far right a number 9 has a green dot flashing next to it. Please help!! Ruthven...


The 9 you see is the maximum "burst" which is (pictures made in rapid succession) and is not an issue with your problem at this time the flashing green dot is the in focus confirmation light and it's good that you are seeing this as we will use it to remedy the problem.

Manual focus switch

What I want you to do is put the AF-MF switch in the manual mode if it's already in manual mode then that was your problem switch to AF and go take some pictures. If it's in AF mode switch to MF make sure teh camera is on and look through the viewfinder at a subject say 15 feet (4.5 meters) away something that has contrast then turn the manual focus ring on the camera slowly until it appears to your ey that it's coming into focus when it's in focus the green light will come on solid, now you know what you are looking for focus an several different objects at different distances and focus manually. Now switch the lens over to AF (auto focus) and focus on the same thing but let the camera do the focusing What auto focus will not focus on in something with little or no contrast like water clear blue sky a painted wall mirror chrome glass and a few other things.
Here is another diagram to check make sure you are in the correct mode.

Now for the focus point in the viewfinder make sure it's in the center position.

To adjust the focus point do this

Once you have the camera set to the center focus point and the correct AF mode (one shot) auto focus should return to your camera. Have fun Robert from London Ontario Canada

After taken photos the image out of focus


On the front of the camera body, below the lens release button you should find a two position switch labeled "AF" & "M" This is the "Auto Focus - Manual" selector switch. Make sure the selector is set to "AF" for auto focusing.

Your lens may have a similar focus selector switch on its barrel. There are two types of switches used - depending on the lens. The first is labeled "M/A" and "M" The "M/A" position indicates it is in "Auto Focus" mode with a "Manual" focus over ride capability. You can simply twist the focus ring to change the focus to a point other than that chosen by the camera's auto focus system. The "M" position is Manual Focus mode. No focusing operations will be performed by the D80 auto focus system - focusing must be done by the photographer.

The second type has "A" & "M" positions. These represent Auto and Manual focus. The difference between this type switch and the "A/M & "M" switch is that when in "A", the camera will no allow the focus to be changed manually. There will be opposition to twisting the focus ring in the position. Forcing it will likely result in damage. The selector switch must be changed to "M" to change the focus.

If either switch is set to manual, the auto focus system will be disabled, so it is very important to have them both set to "A" or "A/M".

I hope this helps. Please rate my reply - thanks!

I have a sony syber shot dsc - H50 i don't know how to get the cam in "manual focus" mode. I want to shoot 1 cm far images.


One problem with most point&shoot cameras is that they are designed to be pointed and shot. The camera takes care of things automatically, including focus.

The H50 doesn't have a manual focus mode. The best you can do for close-ups is to switch to one of the Macro modes. Press left on the control button (marked with a blooming flower) repeatedly to select the desired mode. See page 18 in your manual for full details.

The lens cannot automatically focus


Hi pablo_cornel, One simple question, is the camera in manual focus mode. On the right of the lens mount, as you look at the camera is a switch that reads AF and M. If that switch is set to M you are in manual focus mode. Also, does the 18-55 mm lens have a manual override switch?
