To some this is a easy choice, why would anyone ever want to use manual focus when you just need to press a button and the image is on focus?
I prefer manual focus because it allows me to slow down and spend more time on the composition, i still use autofocus lenses when the subject is moving way to fast and i dont have a chance to set the focus manually but since those moments only happen now and then its not a issue for me.
The choice of manual focus does requires me to do some extra calculating but other then that i dont feel disadvantaged compared to using autofocus.
Here is two example shots from the first of may demonstrations were i only used a manual focus lens to cover the whole event and got excellent results:
With that said i do plan to get the excellent canon 24-70 2.8 L USM lens for when i need autofocus, but for now i am very happy with my Nikkor 1970:s tele lenses that cover everything i need for taking the photos i want :)
What do you prefer auto or manual focus?
Have their been a moment when autofocus was a disadvantage for you?
