I noticed that when shooting outdoors specifically, there is a lighter band going across the top of the frame of my 1Ds (mark I). This occurs especially under bright sun. With an overcast sky, it's either unnoticeable or not there. In shade or indoors, it's non- existant. Occurs with fill flash and without. Occurs at different ISO's as well as different appertures. It stands out particularly when the frame is underexposed and it almost seems like the lighter band is properly exposed versus the rest of the frame. Anyone familiar with this or can give me a clue??

It's a shutter problem--it's not the amount of light per se that causes it, it's the shutter speed. This issue often only shows up at a few shutter speeds.
My 1dsII does it around 1/125, although not nearly as badly. Apparently the shutter is bouncing or hanging up at the end of its travel. Sorry, it's either send it to Canon or learn to live with it.

You most likely have a defective cartridge. It is also possible that your Charge and/or Transfer rollers have become defective.
Inspect the cartridge for any band of remaining toner.
You should notice one or two long thin rollers, with the cartridge removed. There will be a dark roller that should appear textured, but not dull. And they may also be a lighter colored roller with no marks.
These are the three common problems that create lines.
Lastly If the band is mostly straight, it is most likely the cartridge
If the band is wavy or broken in anyway, it is probably the roller(s)
If your watch band have UV sensitive pigmentation in it, there is nothing you can do, but buy the new band. Find your nearest jeweller and ask to clean watch band in ultrasonic cleaner for 1 hour. If this kind of cleaning doesn't help, that means your watch band is UV sensitive and is and will be discolouring more and more by the time. Alternatively you can try to clean it with the lighter fluid (ZIPPO). Soak a soft cloth in to lighter fluid and clean the band. Start with a small area inside band to make sure the fluid is not reacting as dissolver, as some resins react quite vigorously and tend to transform into chewing gum sort of state. And again- if this cleaning doesn't help, the band is UV sensitive and discolouring is taking place. That discolouring is happening becouse some of the colour pigments used in resin manufacture are sensitive to ultraviolet light and when exposed to sunlight or daylight, they react in a chemical way, changing molecular structure, wich we see as the colour change.This process can not be reversed and this is why the band can not be cleaned. Do not forget to rate please.
The Digimax A7 Doesn't work outdoors, because on top of the camera, try taking a picture, but hold your hand on the top of your camera (Cover it) it's light sensitive. On top their is a built in sensor, the Darker it is the darker the picture is, the lighter, the lighter. If you cover it, (Usually on top) It should work fine outdoor, just don' t cover it indoor. Hope this helped. -CA
