ok, this is my question: When you look at the lens, it says: EF-S 18-55mm 1:3.5-5.6, does this mean that these are the lowest aperature settings the lens will accept or is that the largest? The reason I am asking the question is because, when I look through my viewfinder, it's very dark. When I was playing with it earlier it was fine. I think I might have a stuck aperature but I want to make sure there isn't anything that I can do to fix it or understand it. When I went to manual mode and set it aperature priority, it will not take anything more than 3.5 @ 18mm or 5.6 @ 55mm. Whenever I set the the aperature higher than that, it gives me ERR 99. I have taken the battery out and replaced it after charging it and it still doesn't work. I am lost! Someone please help me.
