Do’s and Don’ts Using manual focus
Some simple tips to increase sharpness when you take full control of focusing
Focus before zooming
Once you’ve set your focus distance, avoid zooming the lens as this can cause the focus to shift and you may end with blurred results.
Forget your rotation
Knowing which way to turn the focus ring to move the focus point can mean you don’t miss shots in the heat of the moment.
Consider getting a loupe
It can be hard to see a Live View display in daylight. An LCD screen viewer or loupe can both shield the screen and magnify the image.
Focus too quickly
Focusing steadily back and forth across the detail you want in focus makes it easier to see where the image snaps into sharp focus.
