I used to have a Nikon FE which I use my manual focus lens with. Manual Focussing is by using the split half circle method.
I have since upgraded to a F80D and there is no such half circles. When I want to focus, I have to just rely on seeing wherther the image looks sharp to me.
Although the most of my photos have turned out ok, but I am wondering if there is an easier and more spot on method to know if I've got the focussing right.
