Hi guys, this should be an easy question. I was playing with my 35 1.8 and a dog recently. I don't have any of the shots because I'm at work, but I can easily explain the problem. I have understood that your DoF should be centered on the focal plane of the lens. In other words, if your DoF is 12", DoF should extend 6" to the front and beyond of your focus point. Well it seems as though the DoF is actually 100% behind my focal point; that is to say the focal point is actually the back of the DoF. Everything beyond that point is OOF. Is this normal? Do I just have to work around it?
