Photo Tutorial: The n Reasons for 35mm fixed-focus practice

For new photography, in finding their best and favorite shooting subject, often experience a long time confused: "Everything wants to shoot", but it seems that "nothing to shoot." At this stage most people will choose the manufacturer's big variable Giope as their own hanging nose, because it can meet the need to pull far, but this is really a good choice?

There may be some doubt that the novice to use fixed Jiaozuo hanging camera is not climbing first go, not conducive to basic learning, more just loaded with X components. It is considered that the lens of the fixed focal segment of the Novice not only limits the subject matter, but before the stable shooting technique and the lens sense, the use of fixed focus makes the composition limited, the focus is blurred, and there is no shallow depth of field. But today I will tell you, using 35mm fixed-focus as the advantage of hanging nose. From another point of view, the bad shot is only you do not choose a good set of Coke practice head, use zoom convenient, but absolutely no use of fixed coke progress quickly.

　　One, 35mm is to shoot people with a view can be guarded by the focal segment

If only one set of Coke can be selected, 35mm focal segment is the ideal choice for the fixed focal lens of the hanging machine. As a small wide angle type of fixed-focus lens, it covers a wide range of pictures, both can shoot people, but also the performance of the majority of the surrounding environment to film.

The most recent focus distance of 35mm fixed-focus is usually 0.25-0.3m, a few steps forward can be taken close-up, food, product of still life close-up can have more detail performance; Take a few steps back to the environment description, pure scenery, or even people can, very flexible, this focal section can give the photographer enough space to practice lens sense.

The sense of lens is formed by enough practice, when using 35mm to cope with scenery, portrait, humanities, Night view of various themes of the fixed-focus, the use of frequency and efficiency are very high for beginners, the speed of progress naturally faster, and 35mm, fixed-focus optical structure has a wide perspective and a short range of recent features, It also serves as a useful macro-head function when paired with a high pixel model.

　　Second, fixed-focus high quality 35mm out of the noble

Fixed focus lenses used, use zoom do not have too big obstacles, but the habit of using the zoom after the fixed focus is not necessarily used, because in addition to the difference between the focal segment, fixed focus lens quality and large aperture features are ordinary zoom lens envy does not come. At the same price of the same focal segment lens selection, the quality of the fixed focus is higher than the zoom lens.

The reason is still caused by the structure of the Mirror Group. In general, the fixed Coke will use more high-quality lenses such as fluorite, ultra-low dispersion lenses and nano-coating to improve the light and refraction performance, and fixed-focus lens structure is simple, less lenses, virtually reduce the internal refraction produced by the color problem, high contrast when the purple edge is not easy to appear. By contrast, zooming is not only easy to color, but sharpness can also be compromised by multiple lenses. So the idea of fixed-focus high quality is universal, especially when compared with a zoom with a little difference in price.

In 35mm this gold focal section, each brand has its own signboard fixed focal, like Canon EF 35mm f1.4l II USM, suitable horse 35mm F1.4 DG HSM Art, Carl Zeiss 35mm F1.4 and so on are the typical representatives.

The limitation of the focal section forces the new thought of Meng to be more excellent composition

When you are using a zoom lens, the framing operation may be standing in place, do not need to think much of the rotation of the ring to get to the appropriate scene, and selected the fixed focus, as a result of the focal section limit only a scene, to obtain favorable elements into the screen, to avoid the adverse elements of interference screen, Meng new need to move around, eyes at any time composition observation , and subtract the elements until you find the best angle.

And, after such high-speed movement and observation exercises, you will develop a habit of simplifying the picture and thinking. Over time, when you raise your camera next time, you are familiar with the range of vision of the lens, and with the addition of quick thinking, the brain has naturally formed a picture, and the composition intuition forces you to press the shutter. In other words, with a 35mm-like fixed focal segment, a good picture is automatically present in your mind as you move around the frame, and the composition becomes intuitive.

　　Four, fixed Gio circle makes weak light shooting more favorable

Limited by volume and weight, the zoom lens cannot do a larger aperture. But the aperture of fixed focal lens is generally bigger, common also is f1.4,f2.8 such big aperture, each brand also will attack 35mm big aperture lens, like homebred Han card, even out F0.95 such inverse day aperture value.

With large aperture, in the night or weak light environment, can give the photographer faster shutter and shoot freedom, but also conducive to hand-held photography and maintain lower sensitivity. However, starting from the fixed focus of the new technology is easy to rely on the big aperture, in addition to the big aperture in addition to the night and weak light filming effect attraction, can obtain the milk of the coke outside and the level of the coke outside the transition is also a major reason.

However, although the large aperture is easy to take a virtual soft, large depth of the picture, but if the pursuit of large aperture, will also fall into the same, no characteristics of the big imaginary film circle, this we need to pay special attention to.

　Fixed coke structure simple weight relatively portable

Because the lens group of fixed focal lenses is relatively small and simple in structure, with less concern for volume and weight, the weight of large aperture lenses is not exaggerated. Take 35mm F1.4 lens For example, Nikon Af-s Nikkor 35mm f/1.4g heavy 600g, suitable horse 35mm F1.4 DG HSM Art Heavy 665g, Sony Distagon t* FE 35mm F1.4 za heavy 630g, although the above weight is not small, But even though the Canon EF 35mm f1.4l II USM, which has been criticized for volume control, does not weigh more than 800g (760g), the fixed-focus lens still has a lot of advantages over most advanced zoom lenses, compared to the >800g imaging good zoom lenses such as 24-70mm.

Moreover, as the famous sweep Street lens focal segment, 35mm fixed focal lens with a single sweep street, not only the camera's weight control is perfect, using fixed-focus shooting is not cumbersome, but also to get you close to the crowd, see the use of zoom or telephoto and other large volume lenses can not see the details.

Summary: Hanging nose is always hanging on the fuselage of the lens, it can meet the needs of most of our scene shooting, although the focal segment of the fixed-focus lens is limited, but relatively, it has a higher quality and production process, the weight is relatively more portable. and 35mm of focal segment can be guarded, whether it is shooting humanities or sketches, the use of artificial walking can be used to get the right frame, limit the focus section can also give people more time to think about composition, how to use 35mm focal paragraph to express themes and emotions.
