Hello everyone, Lin Fei to answer the above questions, SLR camera lens recommendation, SLR camera lens choice many people do not know, now let's take a look!

Choosing a lens is definitely a problem that all DSLR users have to face. For beginners, it is even more difficult to make a choice for the moment. So how to choose the SLR camera lens? Before you buy a lens, you might as well figure out the concept of a few shots. Let's give a brief introduction.

1. Quality prerequisite 3354 fixed focus is better than zoom?

If you ask a friend for advice, I believe almost everyone will tell you that the picture quality of a fixed-focus lens is better than that of a zoom lens. This statement is true to a large extent, but not absolutely. As far as the zoom lens itself is concerned, there are several. It is unfair to compare the zoom lens of this kit with the fixed focus lens.

Measured by the number of shots

Fixed-focus lenses are recognized as a good quality, which may prove that simplicity is beauty. Take Nikon AF-S 50mm 50mm ED 1.4G as an example, there are only 8 lenses; if it is a zoom lens of certain quality, such as Nikon AF-S Nikel 24-70mm fhand 2.8g ED, 15 lenses are needed. Since zoom is possible, the addition of the lens is understandable. But the more lenses, the more likely it is to cause some problems, such as 3354 chromatic aberration. With the increase of the number of internal refraction, the probability of light scattering deviating from the optical axis is higher, and the possibility of purple edge in high contrast is more likely. In addition, multiple shots will reduce sharpness. Therefore, the pursuit of picture quality, fixed focus lens is the first choice.

In terms of lens quality,

But too many cameras will affect the quality of the picture, which is not absolutely true. For example, Nikon AF-S VR micro-single Nicole 105mm fanner 2.8g IF-ED has 15 shots, the same as the AF-S Nicole 24-70mm fdeband 2.8g ED, but the sharpness is also recognized as the top level. So the quality of the lens itself is also an important consideration. Advanced zoom lenses will use high-quality lenses such as fluorite, ultra-low dispersion lenses and nano-coatings. To improve the performance of light transmission and refraction, and even if there are many lenses, the image quality can be maintained.

Performance of shrunken aperture

The aperture size also affects the performance of the lens. Usually narrowing the aperture will increase sharpness and reduce glare problems. Generally, the optimal number of lines can be achieved by reducing the two-level aperture, and it is impossible for the naked eye to tell whether it comes from a fixed-focus lens or a zoom lens. In fact, the general standard zoom lens is not very bad, but due to cost considerations, lens quality and correction strength are not as good as advanced lenses, so they are often looked down upon by senior users because they have to reduce the aperture as much as possible in order to achieve better picture quality.

At the end of this article, I hope it will be helpful to you.
