Large aperture lens better or small aperture?

At present, many entry-level users in choosing the lens will follow veteran said: choosing large aperture to, the bigger the better. Admittedly, large aperture lens in some ways indeed has a normal lens incomparable advantages, but small series of the view that the primary players, in many cases do not require large aperture lens, and there is no need to spend more than ordinary lenses for several times the price at the moment, many entry-level users in choosing the lens will follow veteran said: choosing large aperture to, the bigger the better. Admittedly, large aperture lens in some ways indeed has a normal lens incomparable advantages, but small series of the view that the primary players, in many cases do not require large aperture lens, and there is no need to spend more than ordinary lenses for several times the price to buy a large aperture of the lens. Why so? this from many aspects. The following first take a look at the benefits of a large aperture and the camera. The advantages of a large aperture can be regulated as follows: 1. using the large aperture, in the amount of light is large, you can get a higher shutter speed, in cloudy or interior, light environment in poor places of times when this point is particularly important, can effectively reduce the impact of the jitter greatly avoided due to jitter caused by the camera fails. 2. the art of photography usually pay attention to the outstanding principal and the prominent theme using actual relationship is very commonly used method, especially in portrait shoot, showed more pronounced. But to achieve your seeing clearly requires a smaller depth of field. We all know, the aperture size directly determine the size of the depth of field. When shooting in high aperture background blur out the clutter, you can let the work appears more concise.

Useless background processing by blur

Everything is on both sides, so there will be the so-called lost; in fact, large aperture when using certain shortcomings, and not through a large aperture to accommodate any shooting conditions. First, using the large aperture photography it is necessary to pay attention to exact focusing. When using the large aperture is usually very small depth of field, focusing the slightest accidentally, it may cause the offset, that is, we focus usually say ran Coke. If the focus is not, a painting is a failure.

Difficult to focus easily focus offset

Second, Aperture is too big, and excess of the difference is too large and cannot be faithfully restore a panoramic scenery, not conducive to the scenery and unspoilt photography. Have friends carrying his cameras, ran a lot of places to find the pictures out of something worse than others, clarity and depth of field are problematic, but don't know which it is sought after by their large aperture. In addition, large aperture lens usually have a larger volume weight is larger, and the price is hard to accept.

Let's first talk about weight, large aperture lens not only bulky, heavy weight, carrying out also very inconvenient. Go on a journey, is to minimize weight and heavy lens will cause inconvenience of action, and in landscape photography, often use not to too large aperture. Take a look at the price, because the production process, the maximum aperture lenses for each enlargement in mind, the cost of expanding quite a lot, but not only the lens itself is more expensive, and even UV lenses, lens cover such ancillary fittings are expensive. Because the prices are very expensive, ordinary consumers simply cannot afford. Even though enthusiasts bite, buy one, but to buy such an expensive things, I'll have a double nature: take care of it, in case there is a long shot two short, your mood is also not so pleasant? and for large aperture background blur of the good, we can also adjust the lens focal length and change camera and was taken in distance to get the background blur, Aperture large despite its benefits, but also do not have to rely entirely on it. From the above we can see that the blind choice of large aperture lens is not necessary, even with the lens to the camera, it does not necessarily achieved satisfactory results. I wonder if you have not heard of F64 team, this is the world's smallest-level aperture and named. This organization to United States well-known scenery photographer Ansel Adams as representative, they advocated using very small aperture, for a long depth of field and excellent sharpness. They shoot pictures are quite nice. Landscape photography often require a large depth of field, if you shoot scenery with a large aperture, apparently do not meet this requirement, this time, small aperture to reflect its role.
