I would not be suprised if it did that. Unfortunately, especially if you are using the Canonlite D, I use mine with out a battery & with a non-Canon flash so it is not going to do that.

For what it is worth, I have found that mine meters close enough for negative film with an alkaline battery in it, but not for slide film. I tried air cells at one time. Wound up using one air cell per roll of film, because I do not use the camera that much any more, and then lost the adapter.
