How to choose Nikon D7 100 lens?

Nikon D7 100 and Canon 70D are of the same level, both of which belong to the classic models in the mid-range machine.

There are mainly portraits, landscapes and birds:

1, owner's portrait: it must have a fixed focus of 50, and it can be considered to be equipped with Nikon AF 50mm f/ 1.8D+ Nikon AF-S DX Nick18-105 mm f/3.5-5.6g.

2, mainly shooting scenery: mainly focus on the wide-angle end, you can consider buying Nikon Nikkor18-140mmm f/3.5-5.6g EDVR.

3, mainly to shoot birds (shooting at a distance): mainly focus on the telephoto end, you can consider Nikon AF-S DXNick18-200mm F/3.5-5.6g EDVR II, but this picture quality is generally not very good; It depends on the budget. If the budget is enough, you can match two heads: 24-70+70-200.

Basic principles of lens selection:

First, the focal length

The first thing to pay attention to when choosing a lens is the focal length of the lens. The focal length is actually a matter of viewing angle, and different focal lengths have different viewing angles. Wide-angle lens should be used to shoot scenery and telescope lens should be used to shoot people, so you should first decide the focal length of the lens you want to buy according to the purpose of photography.

Second, the maximum aperture

The real value of the maximum aperture is to increase the amount of light entering in weak light, so as to achieve the best exposure combination. Shooting scenery generally does not require the blur ability of the lens, and in addition, except for particularly dark places, the requirements for lens caliber are generally not too high.

However, when the 70-200 mm zoom lens is matched with the 2x zoom lens to make the telephoto lens reach 400mm and focus automatically, it is best to choose the lens with the maximum aperture of F2.8, which is conducive to accurate focusing in dark conditions. Shooting people with a large aperture lens can shoot natural light with a mobile phone even in weak light.

Third, close-up ability

The close-up ability of the lens is another key point after the focal length and the maximum aperture. The same is true for wide-angle lenses, standard lenses and telescope heads. The close-up capability of the existing 50mm standard lens is about 45cm, which basically meets the use.

When the shortest shooting distance is used, the large-caliber standard lens often produces large aberration because of the lens protrusion, which leads to low imaging quality. We should be prepared for this when buying and using. If you use a telescope to shoot scenery, there is not much requirement for close-up ability.
