For those who love photography ALICE, I believe you all know the different functions of fixed-focus and zoom lenses and different advantages, the fixed-focus lens is generally superior in quality performance, and the main advantage of the zoom lens is convenience. Many photography gods encourage newcomers to use fixed focus lens to practice photography, which is why?
Limit to make progress faster
Compared to the zoom lens, Xiaobian suggested novice players with a fixed-focus lens is better, because without the convenience of zoom, you have to rely on the mobile viewfinder composition, more "in person" experience photography experience. This picture taken out, presumably will make you feel more, after all, when shooting more to do. And, because the general fixed-focus lens will have a larger aperture, you can more clearly see the focus and make a choice.
Enhance the sensitivity of the lens focus
Now we are generally accustomed to rely on autofocus, but depending on the camera's autofocus performance is different, in the case of fixed-focus lens large aperture, it is prone to defocus situation, it may be the camera to determine the AF point is not what you want , Or because you moved slightly forward or backward, pay special attention to the part you are focusing on, even with autofocus.
Imaging clearer and sharper
Fixed-focus lens due to the lack of zoom needs, the lens structure is relatively simple, can reduce the diffraction of light in the lens may provide a clearer and sharper images.
Shimmering shooting can ease
Because of the large aperture, the fixed-focus lens absorbs light well in low-light conditions, and is also superior in image quality and shooting performance. Take the maximum aperture of F2.8 zoom lens and F1.4 fixed focus lens for shooting, open the aperture under the premise of the fixed focus lens as the aperture two times larger than the zoom lens, relative to the choice of shutter or ISO can Have more tolerance.
Image deformation is less
Mentioned earlier, due to the fixed-focus lens structure is relatively simple, in addition to some of the wide-angle lens equipped with a floating AF system will have a mirror group, the general structure of the lens does not move the mirror group. Because of this, the lens imaging relative to the more complex structure of the zoom lens, in the same focal length under the image distortion is also less serious.
Fixed focus lens portable
Finally, from the appearance point of view. Fixed-focus lens size and weight tend to be smaller than the zoom lens, portable is also more convenient, will not increase the burden behind the na!
Having seen so many advantages of fixed-focus lens, is it right? Have not touched the fixed focal lens of the friends itch it? Many monocular camera with Kit lens or zoom lens, is it must be the other in the lens of a fixed lens Caixing it? In order to escape the suspicion of persuading defeat, in this still have to tell you that you want to spend a lot of money, but also to experience the fixed-focus lens shooting method, you can find ways to fix their own zoom lens in a focal length, you can practice it ! To the hand when there is a budget, and then start a genuine fixed-focus lens to play, realize it's video charm.
