Tips for Using Micro Lenses

We often use micro lenses to shoot some flowers, plants, insects and e-commerce products, and occasionally use micro lenses to shoot common subjects such as portraits. It can be said that there are still many uses of micro lenses, so what are the tips for using micro lenses?

1. Use micro lenses: When shooting small objects, pay attention to properly narrowing the aperture and control the depth of field

Micro lenses usually have a maximum aperture of f2.8, for example, some big brands have such an aperture design. However, the method of using a micro-lens is not the same as the fixed focus of portraits. When shooting portraits, the subject is prominent and the background is blurred with a large aperture, while for macro subjects, because the shooting distance is short and the focal length is long, it already has a very shallow depth of field. , If you open the aperture again, the clear imaging range will be very small, so when shooting macro subjects, the aperture should be appropriately reduced, usually below f8, to obtain a relatively large depth of field range.

2. Using micro lenses: Choose the Correct Focus Range

There is usually a switch on the micro-lens to select the focus range, which can be the entire focus range from infinity focus to the closest focus distance, or it can be limited to a short or far focus distance range. Because the focusing stroke of the micro lens is relatively long, the focusing range is set to improve the focusing efficiency. When shooting non-macro subjects, you can choose the farther focus distance switch gear, and when shooting macro subjects at close range, you can select the close focus position.

3. Use micro lenses: choose the appropriate focus mode

The micro-lens can focus automatically, but as mentioned above, it has a long focusing stroke, and it is difficult to control the depth of field when it is close to the subject, so it may be necessary to manually focus when shooting macro subjects. The manual focus ring of the micro lens is very wide, and the focus damping and feel are very good. It is a lens suitable for manual focus. However, it should be noted that manual focusing is not a commonly used optical viewfinder, but after selecting the lens focusing mode as manual, open the live view of the LV screen of the SLR camera, and zoom in on the focus for fine focusing, so that the focusing can be completed more accurately.

When shooting with a microlens, carry a tripod with you. Shooting macro subjects, because the shooting distance is very close, even if the light is guaranteed, turn on the lens anti-shake function, and the hand-shake effect may still be magnified. Don't be lazy in this regard, a macro tripod is a standing device.
