Sony recently introduced two quality fixed-focus lenses, all of which are of very high quality. And I also bought this shot one after another, and I also wrote several reviews of it. So many people are asking, both of you are saying good, but in the end there is a difference? If you choose one, which one should you choose? In fact, the answer is very simple, there is no lens to shoot all the subjects, relative to the zoom lens, the scope of application of fixed-focus lens is even more limited. However, the breadth of the zoom is different from that of the zoom water, and the focus is on the depth of the excavation. Therefore, the fixed focus has better picture quality and bigger aperture. However, there are different points of focus between fixed focus, focal points between focal ends with similar focal lengths are very close, so there will be questions at the beginning of the text, 50 or 85, how to choose?
Before answering the question of choosing between 50 and 85, I would like to introduce the three principles for selection.
Try to choose a lens with a large focal length difference. Under normal circumstances, it is generally the first to see what own focal length lens, then the next lens must choose the focal length difference, avoid the focal length repeated shot. The first thing to buy lenses is to cover the coverage of common focal lengths.
Try to choose lenses that do not duplicate the function. For example, 85 coke and 90 micro-distance, although the focal length difference is only 5, but the function difference is huge. One is a portrait mirror and the other is a macro lens. Even if they are both at the same time, the two lenses will not conflict and perform their duties.
Select on demand. The first two principles are very simple and there is no difficulty in implementation. The most difficult thing for me is this principle. We choose on-demand. Many people do not know what their needs are or do not know what the difference is between shots. For example, in this article, 50 and 85, are portrait mirrors, the difference in focal length is not too large, how to choose?
SimilaritiesI think that except for some local residents who want to buy a new lens, most beginners will have such lens selection difficulties. The reason why there are difficulties in the selection of FE85 1.4GM and FE 50 1.4ZA, I think it is because the two shots have too many similarities, so it is so entangled.
Their similarity is first reflected in the price . Both shots are in the yuan class, and the official website offers only 1,000.
Second, the two lenses are suitable for shooting portraits, and the perspective of the portraits is very close. Erasing the camera's parameter values, many people may not be able to tell the difference between 50 and 85 photos.
Once again, the distortion is small , and the aberrations of the two lenses are so small that they are barely noticeable to the naked eye.
In the end, both shots are top quality , and they are not cows. If one of the shots is bad, then don't worry. Both are so cattle, how to do? As far as the quality of the picture is concerned, I sent two photos to let everyone feel free to feel it.

It can be seen that the quality of the two shots is very good. It is really difficult to separate them and the quality of all parties is very close. So if you want to make a choice between 50 and 85, you must dig deeper into the two. The difference between the lens.
the difference1. The shooting distance of the two shots is not the same , the same composition, 50 need to follow some of the stations, and 85 need to be far. This leads to a conclusion that 50 is suitable for indoor and outdoor use, but 85 is suitable for outdoor use. Because 85 needs enough space to display, the interior is very easy to be limited, so in this respect, the applicability of 50 is indeed wider than 85, and it is more suitable for the head of the camera. The closest focusing distance between the two is 0.45 VS 0.85, a difference of nearly doubled.
Therefore, FE85 1.4GM is farther than the FE50 1.4ZA station in the same composition. This is one of the differences. The shooting distance between these two photos is about 0.6 meters and 1.1 meters.
2. Shooting angle. Due to the shooting distance, the available shooting angles of the two lenses are also different. Therefore, in this link, FE50 1.4ZA is still more dominant.
According to the graphic, it can be seen that, limited by the ground, and height is known, the 85 shooting angle is much smaller than 50. Therefore, shooting from many angles is 85 incapable.
For example, this kind of reflexion is 85 incompetent. If the 85 must be forced to shoot from this point of view, limited by the nearest focusing distance of 0.85 meters, even the shutter can not press.

There is also such a backsliding, 85 fixed focus calculations can not be brought to the top of the model leaves.

3. Virtual power. The blurring ability of a camera is related to three factors: the focal length, aperture, and object distance. The same lens aperture value, focal length 85 is significantly larger, the only uncertain factor is the object distance. The same object distance, the shallower the depth of field of 85, the better the blur, this is beyond doubt. But this does not make sense in actual shooting. Because photographers are more concerned about the difference between the two virtual powers in the same composition.
From the two pictures taken from the same location one after another, we can easily judge the full-body portrait. The fuzzing power of the FE85 1.4GM is rolled over 50 1.4. Although this sample map is not rigorous, after all, the height difference between children and adults is very large. The child is 1 meter tall and the model is 1.62 meters tall. If the child is replaced with a model on the left, the white space above the 85 proofs should be sufficient. So basically we can prove that the composition is similar, but the fuzzification ability of FE851.4 is to compress the FE50 1.4ZA.
The blurring power of the portrait is not as obvious as the full-body portrait. Carefully observed, it is still more of a background of 85. If you compare shots with the same scene, you can easily draw conclusions, 85 winning.
in conclusion50 Focusing has a more flexible composition. You can attack and retreat. So is it better to say that FE50 1.4ZA is better? This is not the case, although 50 has its own advantages, 85 also has its own killer. What a photographer needs to do is to avoid weaknesses and fully exploit the strengths of each lens.
85 fixed focus has a stronger blur. If you prefer a slice of sugar, like a creamy soft focus, there is no doubt that 85 is your best choice. In fact, if only the portrait shots are ranked, FE85 1.4GM can basically be taken as the first choice. What's more, the FE85 1.4GM is already the longest focal length in Sony's original FE bayonet, and it is the best focusing head for the blur.
usageThe above said so many theories, then the next part of the actual combat, 50,85 in the end should be how to shoot, in order to achieve strengths and avoid weaknesses, and give full play to the advantages of the lens.
1. Skillfully use the prospects. In fact, whether it is 50 or 85, it is not only the background but also the prospect that the large aperture is out of shape. If you look for the future ingeniously, you can shoot a very fantastic effect.

For example, if the photograph taken through the metal door handle of the glass door is 85, it is impossible to capture the blur texture of the brushed metal, but the whole thing is empty.

This is 85 using the atmosphere created by the chandelier glass. Perhaps this kind of prospect is hard to find, but if you are good at discovering, there are various prospects in your life. For example, 85 has an eternal prospect called ground. At any time, anytime, anywhere, he can be added to the foreground to provide an extended sense of the picture.

When you lean over and use the earth as a foreground, the overall picture is different. The extension of the visual reaches wireless, and even the children’s image appears to be much larger.

This is a trick that can be tried and tested at any time, wherever it fits. However, this move is only used with 85 set. If 50 shots are also taken against the ground, it's too obvious to take a good shot and the requirements for the model are much higher. And the screen will be skewed and used with caution.
The prospect of 50 is better to find it as high as possible, such as windows.

Or is a small gap on a bookshelf. All in all, if you use your imagination to find anything that can do the future, the picture becomes more interesting.

2. Horizontal and vertical. 50 and 85 are all shots of distortion. So when shooting, where there are obvious lines, you should try to keep the picture neat and straight.
This time is particularly able to reflect the 50 and 85 different sense of perspective, and relatively speaking, 50 want to shoot such a horizontal and vertical photographs, the difficulty is much higher than 85. Only by finding a suitable level and perspective can the entire picture be horizontal and vertical.
The 85 is easier to navigate in this area because the distance from a farther angle of view is narrower, and the entire screen is easier to shoot.
3. Lens sense. In fact, no matter whether it is 50 or 85, the most important thing is to develop a sense of lens during the course of use. This is because it requires a lot of actual shooting experience to cultivate. In the beginning, most people relied on the viewfinder to compose pictures, but when you actually shot a shot to a certain degree, even if you get out of the viewfinder, you know how many moves you would take, from which angle you can shoot, you can get What kind of screen? This is the highest level of mastery of a lens for a lens.
Although I don't necessarily have a camera lens in my hands, my heart is always in photography. In daily life, it is good to observe the world from the perspective of the lens. Even if you don't have a camera, you often have such feelings. At this time, if you stand in a certain place and use a certain lens, an exposure parameter, you can shoot it. A great photo. This is the so-called "hand-free mirror, heart mirror" .
Of course, there are no shortcuts on the road leading to the realm of masters, only a large number of real shots .
