Depth of field is inherently shallow at higher magnifications, so there is no room for error when focusing. The slightest movement wi ll throw your subject out of the focal plane.

Use a tripod to keep your camera in a fixed position – it is the perfect focusing aid, and will also enable you to take advantage of your camera’s Live View function. The latter will allow you to zoom in on a small area of your subject in order to check critical sharpness and make fine adjustments to your focusing. I recommend using Live View focusing for close-ups; nothing else allows you to position your point of focus so precisely.
Also, it allows you to see how the aperture you set affects depth of field. By adjusting the aperture while you’re viewing the subject on the LCD you can visualise how much of it will be recorded in sharp focus.
