Photography enthusiasts, portraits, landscapes, which SLR camera should I choose with a lens?

The division of lens focal length: first, the meter head-the so-called standard lens. Its viewing angle is about 43 degrees, and the viewing angle of the photo is closest to the human eye. Different frames have different title focal lengths. The standard lens of 135 film is about 50mm, the focal length of 6×6 title of 120 is about 80mm, and the title of 300d is about 50 ÷ 1.5 = 33 mm ... Documentary photos can faithfully record what you see by using headers, so most documentary photographers like to use headers.

When the focal length is smaller than the pan/tilt, the lens can record images with a larger angle of view, so it is called a wide-angle lens. The shorter the focal length, the larger the viewing angle. The perspective of wide-angle lens is exaggerated, especially in landscape photography, more photos with visual impact can be obtained.

A lens whose focal length is 1.5 ~ 4 times larger than that of the meter head is called medium focus. Generally, the medium focus lens has the smallest deformation, and it is relatively easy to design it into a super-large aperture, so portrait photography is what the medium focus lens is best at. Generally, the focal length of the title is 1.5 ~ 2 times, which is used to take photos of the whole body and chest circumference. Shots larger than 2 times are mostly used for close-ups, and several shots called "portrait king" in the shot all appear in this focal part.

A lens that is more than twice the focal length of the head is called a telescope head. As the name implies, the telescopic lens can achieve "telescopic" shooting, which is mostly used to shoot sports, animals and so on. The application of telescope lens in scenery film can compress the far and near perspective of the scene.

Most people agree that Nikon imaging is sharp and suitable for landscape, while Canon imaging is soft and suitable for portrait and post-processing.

15-70mm camera covers the commonly used wide-angle and portrait focal length, but it does not mean that it can only be used to shoot wide-angle and portraits. For example, some people just take portraits with wide-angle lenses, but they get very special effects.

However, it is recommended that beginners play with headphones before considering buying more lenses, and then you will know more about what you need. The real master thinks about how to shoot with his own lens, not what lens to change. The head behind the camera is far more important than the lens.
