    How to use manual focus in Live View

     

    The Depth of Field Preview button on your DSLR stops the lens down to the selected aperture to allow you to see the area of sharp focus. However, the image in the viewfinder becomes so dark you can hardly see it.

    Many photographers now use Live View to examine this depth of field in detail. Another option is to simply capture an image, play it back, and zoom in to check that everything is in focus.

    Here is a quick guide to how to use manual focus in Live View.

    How to use manual focus for macro photography

     

    Although most macro lenses have autofocus, manual focus is the best technique for close-ups of small subjects. You’ll quickly get frustrated trying to autofocus on a butterfly or bee because even the slightest movement, by you or your subject, will cause the lens to go off on a slow hunt for focus – and by that time the subject is long gone!

    Manual Focus: everything you need to know to get sharp pictures

    Instead, set your lens to manual focus for the distance that your subject will be when at the desired size on the sensor (often 1:1). Now slowly rock back and forth with your DSLR until the subject is at its sharpest in the viewfinder.

    Then gently squeeze off a few shots to maximise your chances of a sharp image (check out these great examples of insect macro photography to see how it’s done!).

    If you do insist on using AF for your macro photography, however, here is our quick guide to how to set your autofocus for macro photography.
