i use MF mostly when i am doing macro of high depth objects where i need to control what is in focus and in landscapes when i am setting focus at the hyperfocal distance. flowers tend to be done with AF because it's the pistils and stamens that need to be in focus and AF is good at locking in on them. insects tend to be done using MF because the eyes don't tend to be easily found by AF unless i am at very large magnifications. virtually all of my bird photos are done using a hybrid AF/MF because i'm using the 1.7X AF extender on the A* 400/2.8. i have to manually focus at least approximately just to be within the AF range of the extender and then lock in by half pressing the shutter. if it's not exactly where i want it, i can touch up with the focus ring on the lens. if i happen to be tracking a moving bird as it flits from branch to branch, the camera is on continuous AF mode. my camera is on a tripod virtually all of the time and the notion of focusing and them composing is weird to me. that's what many AF sensors spread out over most of the FOV is for.
