What is the knowledge of the lens?

Lead: The camera is something that everyone knows better. The lens plays a very important role in the camera. The lens can determine the camera's photo effect, and the camera's photo effect is what everyone cares about most. Therefore, it is very necessary to learn the knowledge of the lens well, which can not only make us know more about the camera, but also improve our photography or photography technology after understanding the knowledge of the lens. The following is the knowledge about lens that I have carefully arranged for you. Welcome to refer to!

First, each "head" must be a boutique.

Friends who are keen on photography often mention "the power of standards", because no matter whether it is daily life photos, portrait photos or excellent works that win photography awards, there are indispensable 50mm fixed-focus figures. Relatively low price, large aperture and moderate focal length are undoubtedly necessary lenses for every photographer.

Second, learn to shoot with a fixed focus lens.

Set the focal length of your digital camera to a fixed value, or install a fixed-focus lens to shoot, forcing yourself to use footsteps instead of zooming. In this process, you will find many different shooting angles. Because when shooting at fixed focus, because of the limitation of focal length, people will think more and you will have to make more efforts, so that your skills can be improved more easily.

Third, prevent hand shaking.

Canon's IS, Longteng's VC and Sigma's OS, even if these powerful anti-shake lenses are installed, your hands are shaking, and the actual picture quality will definitely disappoint you. So when shooting, you should tie the horse stance just to prevent the hand from shaking, and then use your powerful lens.

Fourth, remember the pros and cons of the lens

Zoom lenses have advantages and disadvantages. The advantage is that it can be used to shoot various scenes. The disadvantage is that you forget that your steps exist. When shooting birds, you will also find how much you want a lens with fast focus.

Tip:

When you shoot a distant object with a telephoto lens, you can imagine whether it would be better to be close to the subject if you used a standard lens.

Fifth, aperture will bring depth of field.

A large aperture can obtain a very shallow depth of field, which means that the subject is clear and the foreground background is blurred. This method is often used in portrait photography to highlight the theme. By adjusting the aperture size, the object can be clearer.

6. When the macro magnification is high, moving people themselves is better than zooming.

Seven, there is no perfect lens.

There is no perfect lens, and many lenses have different degrees of distortion. Even the best quality lens, tested under extremely strict conditions, will have different degrees of deformation and distortion at the edge of the lens, and it is impossible to completely eliminate the distortion.

Eight, the lens is very interesting.

A fisheye lens can produce an extreme effect, which can be used not only outdoors, but also in small shops and cabins. Super wide-angle lens and shift-axis lens are also very fun, and the effect is very interesting.

Nine, photography is about technology, not lens.

As for the final film, we all know that excellent scenery (people) is the most important. Playing with a SLR camera is just like practicing martial arts. At the end of the exercise, you will be surrounded by grass and trees. As the saying goes, a bull's head is a dog's head, and a dog's head is a bull's head. Actually, it's all good. This is the most formal photo, my friend.
