How to focus on SLR macro shooting

Lead: With the popularity of digital SLR, more and more consumers directly regard SLR as the first choice to buy cameras, and more DC users have begun to upgrade their machines to SLR. But a problem that puzzles novices comes one after another: how to focus the SLR macro shooting? Let's have a look.

What is a macro? Why use macros?

Simply put, macro is the closest focal length of a lens. In other words, when we shoot something with the closest focal length of the lens, it can be called macro photography in a broad sense.

Why use macros? Because many times we need to shoot some small things, such as flowers, birds, fish and insects, such as close-ups of some objects, etc., we need to use macro photography at this time.

After knowing what macros and macros are, let's go back to the original question:? What's the difference between digital SLR and DC macro?

What's the difference between digital SLR and DC macro?

Those users who transition from DC to SLR will find that DC has a button to turn on macro, but SLR is gone; The macro-enabled DC can achieve the near focus of 1- 10cm, while the nearest SLR focal length of standard zoom lenses like 18-55 and 18-200 is usually between 20 and 45 cm. Does this mean that the macro capability of SLR is not as good as that of DC?

With the macro switch of DC, after the macro function is turned on, the nearest focus distance can usually reach 1- 10cm.

Canon 18-200 IS lens, the closest focus distance is 45cm.

In fact, the key to macro photography is not only the nearest focal length, but also the magnification. Magnification is the ratio between the actual size of the object and the imaging size. With the same recent focus distance, the larger the magnification, the better the macro capability of the lens. The magnification of non-macro SLR lens is usually between 1:2- 1:4. The magnification of macro lens can reach 1: 1, while the magnification of DC is much smaller than that of SLR, because the size of image sensor is much smaller. Therefore, although the short-term focusing distance of non-macro SLR lens is less than DC, the actual performance is even better under the concept of magnification.

How to shoot macro with digital SLR?

Then, how can a digital SLR shoot a macro without a macro start key?

As mentioned earlier, macro is the closest focal length of the lens. Broadly speaking, shooting with the closest focal length of the lens is called macro photography. Therefore, when we need to use a non-macro SLR lens for macro photography, we only need to move the lens to its nearest focal length to shoot.

Non-macro lens macro photography: move the lens to the nearest focal length to shoot.

In addition to this method, a better method is to choose a macro lens specially used for macro photography.

Macro lens specially designed for macro photography

Macro lens has inherent advantages in macro photography, because its magnification is larger (the magnification of most macro lenses is 1: 1, which means that the subject can be imaged in a camera in equal proportion) and the focusing distance is shorter. If you really want to play macro photography, there is no doubt that you must choose a macro lens.

How to use the macro of digital SLR?

Macro photography is characterized by a very small depth of field, which can obtain a very beautiful Jiao Wai effect. Many friends who like macro photography are attracted by this special effect.
