It's natural to take portraits with a better DSLR. Although many photographers are proud that they never take portraits, if you have to take some portraits, it's really a grievance to you. Here, Mr. Herman has a simple selection of portrait mirrors for your photographers who need them. Take a test.
The focal length of a standard zoom lens is about 18-55mm, and 24-70mm for a full range. The focal length of 18mm (24mm) end can be used to take portraits, and 55mm (70mm) end can also be used, but what is the difference? 18mm (24mm) belongs to the so-called wide-angle end. When shooting, it can take a wide range of scenes, while 55mm (70mm) can take a larger image at a greater distance.
We can see from the actual and side photos that when taking portraits at wide-angle and telescope, if we want to take a portrait of the same size, the wide-angle photographer is very close to the subject, while the telescope is a little far away. If it's too close, it may make the person who is being photographed feel uncomfortable. It's better to use telescope. In addition to the problem of oppression, if we look at the background effect of these two portraits carefully, we can see that the background of the wide-angle portrait is more and more complex than that of the telescope, and the background of the telescope is less and simpler.

Constant large aperture & amp; general standard zoom lens
Normally the standard zoom lens purchased with the camera is not a constant aperture design, so the aperture at the telescope end is usually smaller, and the shallow depth of field effect of the small aperture will not be too obvious. Here we simulate the effect of a standard zoom lens in general and the effect of a constant large aperture standard zoom lens in a large aperture.

Standard zoom lens & amp; large aperture focusing lens
If you are obsessed with the effect of clear subject and ambiguous background, a large aperture focusing lens is a good choice. Compared with the large aperture focusing mirror, the standard zoom mirror with constant large aperture has better versatility, but its price is higher. Focusing lenses are expensive and cost-effective depending on their specifications.
For non-full-width (APS-C), 50 mm F1.8 is the first choice, while for full-width, Professor Herman suggests 85 mm f1.8.

If you want to shoot the whole body, but with a shallow depth of field
If you want to photograph the whole body and have a shallow depth of field effect, you have to use the so-called large aperture focusing lens. Normal Kit mirrors or standard zoom lenses with large apertures are not easy to photograph. When shooting, besides opening the aperture as far as possible, the farther away the subject is from the background, the more obvious the effect is. The 35mm and 50mm focal lengths are very difficult to photograph the shallow depth of field of the whole body composition on the APS-C fuselage, but very easy on the whole frame. If APS-C is equipped with 85mm comparisons, it will have the opportunity to photograph the shallow depth of field of the whole body, but the subject will be far away from the photographer.
Large aperture focusing lens suitable for portrait photography
There are many kinds of focusing lenses with large aperture. Herman suggested that friends who are just beginning to learn should choose a 50 mm (APS-C) frame, and an 85 mm frame should be suitable for the full frame. It is easy to take shallow depth of field when taking bust portraits, and the distance between the photographer and the subject is moderate.
