How many lenses do ordinary photographers need?

1, how many photos you need depends on your subject. If you don't pursue image quality, you can shoot everyday subjects, and it is also convenient to wear a 18- 125mm head.

2. If you need to shoot scenery, you can buy a wide-angle lens below 17mm, which is of course expensive, hehe.

3. If you need to take a portrait, buy a fixed-focus lens with a large aperture, such as 105mm/F2, 50mm/ 1.8 (cheap);

4. If you need to shoot macro, just buy a macro lens of 90mm and105 mm..

In a word, there are no fixed rules. What kind of lens you want to buy is a photographer.
