Need manual for Olympus Stylus 850 sw camera

Perhaps you (accidentally) switched the card to lock? or pressed the write protect button for some pictures?
Make sure the lock switch on the card is in the up position like on the picture:

you can format the internal card, see Manual
Olympus Stylus 770 SW Instruction Manual

Search for internal Memory

You have used it 100 time or took 100 photos?
If the camera is still within the warranty period Olympus will repair or replace it.

i don't have the solution but i experienced the same problem on my olympus 850sw

never see this kind of error ever a camera had

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

same thing happens to mine. olympus wants to charge me more than the camera cost to fix it. It started doing it one month after the warranty expired. The problem does go away for weeks at a time sometimes but always comes back so camera is not dependable. If you shake/hit the camera repeatedly it sometimes fixes itself. Olympus sucks.

Well it might be waterproof, but it may not include saltwater proof. I think that is the case. If so, then the salt got into your camera and caused something to not work. I would take it in Olympus and let them look at it. It could just be a bad camera.

My guess the lcd screen was faulty or the water leaked in there and shortcircit it.

go to page 38 of the operators manual if you dont have it send blankemail with 850 manual in subject line and ai will send it to you

This camera has a fixed lens and there is no way to change the aperture for the camera. It is a simple point and shoot model camera. The camera whether in Auto or Program mode will determine the best aperture and shutter speed to use based on the lighting conditions you are shooting in.
