I see manual focus as an 'option' now; it's available if I want it. But it is extremely rare that I personally use MF. The servo-focus on today's DSLRs is extremely fast and accurate, far more so than manually focusing. This is especially true for BIF photography.

I am hoping this new focusing screen will allow that...that it will show more contrast. I agree that auto focus is great, but the lens I am using or birding is manual only. It is a nice lens, and I do not mind manual focus, but when I look through my view finder, I will see a nice bright focused image....just need to be able to fine tune it and right now there is no way to do that! One day I will invest in a new lens for birding.
I'm using a plain matte focussing screen in my camera (if it were glass instead of plastic it would be called ground glass). The technique that has worked best for me and was used for many years before autofocus is to train yourself to recognize maximum contrast. It coincides with optimum focus but our eyes are much more sensitive to contrast than to the detail our lenses can produce.

Last week I found a nesting box where tree swallows were "fighting" each other constantly in mid-air (male and female, so I guess it was some sort of mating thing). With trees in the bg, it was impossible to get a good shot, so I focussed on the box, switched to manual to lock the focus, turned my camera to get the box at the edge of the frame, then fired away every time they got near - eventually I got some good shots in the area of focus.
Before digital I had a Minolta X-700, and it had a split ring surrounded by a ring of diamond-shaped thingies. Made focusing SO easy!
