macro shooting, you need to start from the smallest - macro lens. Macro lens is dedicated lenses for close-ups with a magnification of 1: 1 (in other words, 1.0x magnification) and at the ideal focal length range of 85 - 105mm. But if your lens is not in the ideal focal length, 40mm or 60mm example is, you do not worry, because the focal length affects only you can easily observe, easy to focus the subject or not.

Select the appropriate macro lens deviceFor the selection of technical equipment, the selection ratio of macro lens magnification factor is extremely important. Macro lens magnification ratio standard is 1: 1, if the ratio is less than 1: 1 lens mean it is not a macro lens. Also, you need to select the lens focal length to suit each type of entity. For example, the lens has a focal range of 50 - 65mm, you can capture fabric, wool, jewelry or small mechanical parts, electronic. But if lens focal length of 85 - 180mm lens, this is great for you to take flowers and insects.

2.Manual focus adjustmentA beautiful photos always must have clear criteria and photos are sharp. Criteria for macro photos and also to distinguish them from other types of images are external factors there are two other criteria such as depth of field (DOF). To increase the depth of field you need to be as small as possible aperture and autofocus by hand - technology used to sharpen the region where the object.
Recipes for you to get a "
soi cau" easy focus is not enabled automatic mode of the machine that is the pose. You try to put the machine back, who poured forward direction, there must be more easy to focus not it?
