Focus problem. Coolpix 5000 mounted on Nikon microsocope for photographing tissue slides. Perfect digital images for years; now 90% poorly focused. Image viewed through microscope in perfect focus, image...


If you are initiating the shutter manually, it is quite possible that the camera has become very slightly loose at the F-mount. So, when you press the shutter button, the movement though it may be extremely slight, is shaking the camera at the exact moment you are taking the picture.
Make sure that the camera is tight to the F mount and that the F mount is secure to the microscope.

If you are initiating exposure via software, it is still possible that there is still some slight movement on your desk.
Remember, the slightest movement is magnified many, many times to the camera.

Canon Digital Rebel autofocus problem (EOS 300 and 350)


Hi.

A number of complaints from Digital Rebel EOS owners reported that the auto focus feature suddenly stopped working. In some case the picture was showing a dark shadow on the lower side.

The problem is a factory defect caused by a factory defective autofocus sub mirror. The problem is known to most repairers ( and sadly to users ). Although the defect due to design problem, Canon never acknowledge that this is a factory defect, and never issued a recall and free repair notice for Digital Rebel defective autofocus.

THe repair is done replacing the mirror. The cost ranges between $120 and $180.

As first line of action, check any of the links below, and call Canon. Complain, and see if you can get discounted repair.

If that does not work, the alternatives are using the camera with no AF, or having the camera repaired at own expenses. Often the sub mirror may get even more stuck, and pictures start showing the black shadow from mirror on lower part of the picture.

This is the cause of your troubles:

Here one of several repair websites dealing with the problem. I quote:

"Most autofocus repairs are related to problems with the small mirror under the main mirror (known as the sub-mirror). There is a plastic post that operated this mirror which sometimes breaks. We replace this post with a brass pin so that the problem will not recur. "

Here one of the many forums on the problem. Please read the testimonial from other users, it is quite instructive.

Other forum.

Here replacement pin.

Here how to do the repair.

Here Canon contact:Canon technical support phone number.

Good luck.

Video instruction manual for a AGFA ePhoto


Most any user manual can be found on the NET. Search for your camera name and model for a user manual.
You may have to pay for certain ones. Sometimes you may have to join for free a manual site. They may not charge, but may expect you to give them some manuals sometime...still free.'
