This page lists known limitations of Cam2Com and work around them.

• Some cameras may not work with Cam2Com even though they are said to be supported.

  One example - C-4040Z with firmware version v552u-A78. Upgrade firmware to v552u-A79 and it should work. To upgrade the firmware, send the camera in to a service center. The Firmware Compatibility Chart lists known working firmware and upgrades.

  How to check the firmware version:
  You will need any picture file that had been taken with your camera. If you have a utility that can read the EXIF header information, check the value of the 'Software' tag. If you don't have such a utility, open the file in a text editor like Notepad and search for a string beginning with "v552," "v553," or similar. This string is the firmware version. The whole string looks like v553u-77, v552u-A79, etc.

• At least in some cases, when the media card is full, Cam2Com may show the error, "Bad response received from camera(0x0D)". When the camera is disconnected, the error may be "Invalid parameter range(0x02)".

• Some cameras produce a "CAM_DC1_RESPONSE" error when opening the "Capture Properties" dialog and under some other circumstances. This error has been reported for the following cameras:

  Camera	Firmware producing the error	Firmware that works
  C3030Z	v351u-75	v351u-78, v351u-80
  C3000Z	v353p-73	v353u-74
  C700UZ	v352p-75	There is some, but I do not know the version

  Cam2Com tries to ignore this error, but this means that it cannot get the current exposure, aperture, and program mode settings from the camera so you will have to set desired values by hand before taking picture..

• Working with "Wheat" cameras, never try to access the camera from multiple applications at the same time, like beginning downloading pictures in Camedia Master and taking a picture using Cam2Com. This reliably produces a blue screen on Windows 2000. Also, when my "Wheat" camera ran out of batteries and Cam2Com tried to access it, my Windows 2000 computer rebooted. I believe this is an Olympus USB driver problem. It seems "Rye" cameras do not have these problems.

• I made all possible precautions to prevent you from doing several different tasks with the camera at the same time in Cam2Com; it just does not work and produces funny errors. However, it is certainly safer to wait until one task is over (like picture is completely taken, downloaded and displayed) before pressing any buttons in Cam2Com again.

• You can turn LCD on and off using Cam2Com. Make sure that the LCD is OFF when you disconnect camera cable from the computer. Otherwise you may not be able to turn the camera off. In this case either briefly remove batteries from the camera or turn the camera back on, connect it to the computer, turn LCD off using Cam2Com, and then disconnect the camera again.

• Sometimes a camera can get stuck in some strange state and becomes completely unresponsive, so that even turning it off does not help. Briefly disconnecting the batteries always helps in these cases.

• Some Capture settings, when set to the camera, take effect on the picture, but settings as the camera reports them have different values when the picture is downloaded to the computer. These different values are written into the EXIF header of the picture file. This is by Olympus design, do not ask me why. If a setting read from the camera differs from what was set by Cam2Com, it is displayed in parenthesis under the picture in the Cam2Com window. If the meaning of this value is not known, then it is displayed as a number with a # before it.

• When Cam2Com writes a zoom value into the camera, the camera does not necessarily set zoom to that exact value but to one close to it, which the camera selects by itself. Normally, that value is slightly less than the desired value. Because of this, Optical Zoom is not restored exactly to the previous value after canceling the Adjust Optical Zoom dialog or loading camera settings from a file.

• After changing zoom, the camera sometimes goes out of auto focus. You can fix this by setting the camera to manual focus and then back to auto focus (or macro mode). This usually helps.

• You can set zoom using camera controls connect it to the computer and only after that. In this case, be sure to turn off the LCD before connecting the camera to the computer. Otherwise, the lens resets. After connecting the camera to the computer, you can continue controlling the LCD and zoom from Cam2Com.

• When focusing your camera manually, it is not possible to programmatically enlarge the image on the LCD as when manually focusing the camera using its own controls. This is a hardware limitation. Cam2Com allows using Digital Zoom to achieve practically the same result.

• While copying images to clipboard is supported, doing so is not advisable because multiple conversions from JPEG to bitmap will take place so image quality will suffer and extra information in the image file will be lost. Just save the file and load it into an editor or viewer.

• When rotating TIFF images, Cam2Com has to re-create the whole TIFF file. During this process some proprietary tags may not be copied into the new file, but the image itself, camera information, EXIF header, thumbnail, etc. are copied and are compatible with all TIFF viewers and editors. The thumbnail inside the TIFF file is not rotated when the main image is rotated.

• For some reason, "Wheat" cameras (at least C-3030 Zoom) can only be accessed by the computer to on the second attempt on Windows XP SP2. The first attempt produces a long delay (about 30 sec) and returns "unknown error." I automated that second attempt, so usually Cam2Com can connect to the camera (after the delay). However, if it still does not connect and the camera window displays "Disconnected," refreshing cameras in the Tools menu usually helps.
