Question about Toshiba PDR-M700 Digital Camera

2 Answers

Focus There is one problem that I have with this camera - Auto Focus in low lighting and it has really limited manual focus. Outdoors this camera is outstanding, I haven't found any pitfalls outdoors yet. 10x optical zoom plus 2.5" LCD WOW. Although the LCD is littly choppy, but I don't care about that, pictures turn out really gooood. Anyways back to Auto Focus problem. Do any of you have the same problem? Or this is my ability problem? That limited manual focus really bugs me! I'd like to hear your thoughts about this camera. Cheers.

Re: Focus

I have similar problem. So I use manual focus (1m,3m,inf) & move camera for finest pix. On AF, the adjustment seem to go past sharpest image point but settles on a fuzzier setting. Is there any place that can make a repair?

Re: Focus

I suppose you really can't do much when camera is set to Auto Focus? All you do is aim and shoot? Everything is set up for you. Not so sure about limitations on manual focus. Don't you have different setting when shooting indoors? Good luck.

The reason the camera has the green light is not to warn that the flash is off. The green light is used to help the camera auto-focus in low light situations. If you disable auto-focus and use manual focus the green light should not flash when taking the picture. Let me know if that helps!

Will not take pictures


Does your lens try to focus or it doesn't try at all? You will have to understand that for the camera to autofocus successfully, theere should be adequate light and contrast. That means, autofocus often fail to focus even colored walls or objects under dim light. If you tried all this in daylight, outdoors, then the autofocus sensor is faulty. Please reply with details of how you tried the af.

Lens will not auto focus with flash up


Not sure of you camera model, but the flash will fire momentarily when you try to focus indoors as there is not enough light for the auto focus to work. This is so the camera can determine a distance from the subject to the camera. This is called focus assist (ref to your manual). It will work outdoors as there is enough light and contrast for the focus to work.

Kit lenses included with the camera are notoriously known not to focus well in dark conditions.

Try removing any filters, if you have any on the lens. Check the front and rear lens elements for dust/fingerprints and clean if necessary. Check the mirror (remove lens and take a look) and very carefully clean if dirty. Remove the lens and gently clean the gold contacts on the back of the lens and in the lens opening of the body with a pencil eraser. Don't let the bits fall inside the body. Try the focus outdoors in good light of a scene with lots of clutter in the frame to see if the problem only occurs in low light. Check the menus and make sure the focus assist lamp is in the on position. Let me know if these solve your problems.

Hi, there are many reasons why a camera may produce less then sharp pictures.

1) Dirty, oily or damaged lens: Check for dust and fingerprints.
Clean lenses with extreme caution, using dry lens paper.
Use only minimal pressure and gently wipe from the center
outwards, NEVER in circles.

If the lens is really dirty, ask a professional photo dealer to
clean it for you as a free courtesy.

2) Check to see if the auto-focus is working correctly, this could
be an electronic or mechanical problem requiring servicing.
Focus the camera on sharp image at various distances,
to see if it responds by moving the lens.

3) Can you focus the camera manually?

4) Can you focus by moving the camera back and forth
in regards to the object of interest?

5) Is the auto-focus feature somehow disabled in the menus ?

6) Are the batteries up to snuff, they may be strong enough to
turn on the camera, but too weak to move the focus motor.

7) Is the subject you are trying to focus on out of the
focus range of the lens: i.e. too close ?

8) Is the subject you are focusing on too bland, with insufficient
detail to activate and lock the auto-focus.

9) Do you have enough light for the auto-focus to operate.

10) Does the flash unit project an red pattern to help with
focusing.

11) Are you mistaking sharpness (focus) for depth of field.
In low light conditions, the lens iris opens wide, just
like your eye, to let more light in.

This results in a loss of focussed depth of field. This
means that focusing becomes much more sensitive
and critical, such that (when) the main subject is in focus,
everything behind and in front of the subject is not.

This is a theoretical limitation of all optical lenses:
The greater the focal length and the greater the aperture,
the shorter the depth of field.

This can actually be very beneficial when shooting a
portrait: Focus on the eyebrows, blur the background,

or it can be very detrimental: When trying to magnify
a butterfly on a tulip in low light conditions, getting
everything in focus is impossible.

12) Are you mistaking motion blur with lack of focus,
due to slow shutter speeds.

13) Are you shooting in very low light conditions,
causing the picture to become more noisy,
due to the way the digital camera sensor works.

14) I you come up empty on all these suggestions,
you probably have a defective camera and it is
warranty time:

a) Defective electronics
b) Defective auto-focus mechanism
c) Defective lens, loose internal elements
d) Detached sensor chip
.... etc

Try to isolate the problem. Try to manually and
automatically focus on a wide range of subjects,
at various distances, in bright daylight conditions.

If you are still unable to focus the camera,
it is probably defective and requires replacement
or servicing

BTW
Quick review of the internet, indicates that
this particular model is notorious for high battery drain
and battery connection problems. This may be the cause
of poor auto focus as indicated above.

Also this camera has insufficient internal memory, and
and an add-on memory card is required. It is possible
that without the memory card, the camera is defaulting
to a very low pixel resolution, in order to save memory
space, thus creating the appearance of poor focus.

The nominal resolution of the camera = 7.2 Mega Pixels
is respectable for such a low cost camera, but the
reliability reviews are not good.

This is the camera trying to give itself enough light to focus with.

As it uses contrast to focus with you will get problems in low light conditions. There's no way round this I'm afraid except to light the subject better. As it's a digital camera and you're not wasting film, try manual focus and see what results you get.

Flash problem


That is normal operation, if poped up, the flash fires rapidily in low light to assist the auto focus, on a plain white wall, it can't focus, see the manual on AUto Focus limitations.

The subject is very blury or out of the picture


You are expecting too much for any auto mode. When shooting under low light conditions, the camera may take longer to achieve focus lock. If the subject is moving too, it will take even longer to lock focus. Try using manual focus for the conditions you described.

Low light with auto-focus


All auto-focus systems need a fair amount of light or contrast to work efficiently. If possible, raise the ambient light if indoors. Search for an area within the desired focusing point with contrast to focus on.
