Having problems with your Canon Rebel XT / EOS 350D Digital Camera ?

Extremely long time writing to CF card

\015 I shoot mostly at night. \302\240Long exposures, star trails, etc. \302\240 When I shoot anything longer than half a second, the camera takes just as long as the exposure took to show up on my preview screen. \302\240\015\012\015\012\015\012\015\012Ex. I shoot a 5 minute exposure at f/4.5. \302\240From the moment the shutter closes, it takes 5 minutes to write. \302\240Same goes if the exposure is 5 seconds or 5 hours. \302\240It always takes the same amount of time.\015\012\015\012I know this isn't supposed to happen because other when I've shot with other canon digital rebels, they do not have this problem. \302\240It isn't the speed of the card, either.\015

Answers :

IIRC these cameras support a noise reduction feature through a custom function. The camera will take a second exposure with the shutter closed (i.e. against something pure black) to see which pixels in the camera are "hot", and then will use that information to remove that hot pixel noise from the original image. "hot" pixels depend on temperature and exposure length so the camera would need to do this on every shot.

Epson 750Z won't take pictures with new 2gb Sandisk ultra II compact flash card. When I press the button to take a picture, the green light turns to orange for a long time. With the Ultra card in the camera, the lens takes a long time to return to the Off position after turning off the camera. It will still take pictures using a Lexmar 32mb card.

Was loading pictures from SD card and frame appeared to lock up. It went blank and will not respond even after turning on and off and unplugging for a long period of time. Tried a different card -- nothing -- no response. Called technical support for Smartparts and she had me connect it to my computer -- computer did not recognize any new hardware. Warranty is only 90 days and I've had it six months. Smartparts tech support says there is no repair available. HELP!! Thank you. Barbara

Hi. I have some pictures on my camera memory card which I want to download, but when I connect the camera to my computer, it only displays one picture old picture which should have been deleted long ago and none of the pictures currently on the memory card. I have just run the anti-virus program when I connected the camera, but no threats were detected, although I previously downloaded pictures on the same computers which did indicate a threat or virus at the time.


Instead of connecting the camera to the computer, use a card reader to directly transfer the pictures from your camera's memory card. It is easier and the card reader is a cheap device. It will work just like a USB flash device. ... Samsung Digimax S500 Digital Camera
