Might be a silly question but what is the most effective way to get better at focusing manually? I know all purists will say just keep shooting but in this day and age I would think we would have found a more effective way to practice. I've read online some people use a measuring tape to practice (shooting wide open and randomly picking spots on the measuring tape to practice). Are there any better ways out there to train? However silly this might sound but...are there are any software/hardware out there to help you train?
