I use autofocus. While shooting indoors I usually only use the center focus point since it's more likely to correctly lock the focus due to its higher sensitivity than the outer focusing points. Aim at what you want to be in focus, half press the shutter to lock the focus, recompose and take the photo.
ok great! thanks for this tip... and as for regular photography? I usually use manual focus, than half-press the shutter and then regulate the focus manually until the focus-dots become red. is that correct? thanks a lot!
