Could one of you kind people who have been testing the F5 battery consumption answer a question for me. I have *heard* that the 1005 pixel matrix meter uses a lot of power, compared to centre weighted or spot and may contribute to heavy battery drain. Could anyone confirm or refute this for me? On a related note, if you are getting 15 rolls from lithiums, you have a problem. Since switching from alkalines to lithiums in my F5, I've pretty much forgotten how to change batteries. Many thanks, Stewart
