What s next in When I use zoom, the masters use fixed focus ?

Fixed focus has a very accurate focus performance ability and analysis ability, the image is very sharp, to quote the words of the master of photography, in fact, the gap is between "almost accurate" and "very accurate", magnify the ** of your zoom head to 400%, just look at the edge of the object. I have compared EF50mm and Tamron 17-50mm, and at the same aperture, the ** of the fixed focus head is very sharp.

Wide variation and fixed focus depend on how well you are at it.

Of course, zoom also has the advantage of zoom, from 18 to 200, as soon as you pull the lens, it will pass, and the fixed focus trot all the way can't catch up with you, :)

From a dialectical point of view, a good photographic work needs to make achievements in color, light, shadow, composition and concept.

Zoom and prime lenses are just tools for photography and require a lot of other hardware and software to work best. Among them, the human factor is the first, and opportunities and opportunities should also be one of the more important factors.

The photographer who is called a master has skills that are not comparable to ordinary people, and it is up to him what kind of lens he uses. As long as ordinary people feel that which lens is suitable for them to use in a certain period of time and a certain occasion, the question of which lens to use will not become a puzzle.

When it is time to fix the focus, it is a waste to use the zoom; When it's time to zoom, use a fixed focus, that's a sin.

Cameras, lenses, and accessories are tools, like a carpenter's saw, hammer, and nail.

Pay more attention to the changes in the picture, pay more attention to the layout of the picture, and pay more attention to the changes in the subject.

Don't care about the focal end of the lens, don't care about the shutter speed, don't care if the aperture is f8 photography needs to be shot with a lens, but you need to use glasses to observe.

It depends on what you shoot, the subject matter is different, the requirements are different, and the lens selection is naturally different.

It is not necessarily a master who uses prime focus.

The one that uses the zoom is not necessarily a rookie.

Overall, the image quality of the best zoom lenses is at best tied with that of prime lenses, and it is difficult to surpass them.

The person who says this will not be a master in his life.

Forever unassertive.

Optical zoom is produced by a change in the position of the lens, the object, and the focal point. When the imaging surface moves horizontally, the vision and focal length change, and the farther scenery becomes clearer, giving the impression that the object is progressing.

Obviously, there are two ways to change the angle of view, one is to change the focal length of the lens. In photographic parlance, this is optical zoom. The focal length of the lens is changed by changing the relative position of the lenses in the zoom lens.

The other is to change the size of the imaging surface, that is, the diagonal length of the imaging surface is in digital photography, which is called digital zoom. In fact, digital zoom does not change the focal length of the lens, but only changes the angle of view by changing the angle of the imaging diagonal, resulting in an effect equivalent to a change in the focal length of the lens.

First of all, we need to understand two concepts: zoom and focus. Zoom is the process of resizing the focal length, while focusing is the process of closing the focus at the same focal length.

From this, it can be said that zoom is a physical process, while focusing is an optical process. There will be two rotation rings on the zoom lens, one is called the zoom ring, which is used to adjust the focal length; One is called the focus ring, which is used to shoot in focus. For example, for a 24-70 lens, if you turn the zoom ring, its focal length can go from 24 to 70; At 50 focal lengths, turn the focus ring and it will lock onto the subject (make it clear)**.

1 object distance + 1 image distance = 1 focal length, this is a physical formula, in which the lens focal length is unchanged, it can be seen that the image distance is inversely proportional, according to the different objects you need to focus on, resulting in different object distances, according to the formula to get different image distances, you need to manually adjust the image distance.
