I'm a novice. Can I get into Canon 7d? If possible, how to match the lens? I'm going to add a 1 to the 5mm spittoon

Your idea is quite good. For an entry-level machine, the lens is 5 +18 135, which is quite correct.

18 55 not only has a short focal length, but also has the worst overall quality among all Canon SLR lenses.

18 135 is used on 7D, and the actual equivalent focal length is 28.8 216, covering all daily focal lengths.

5 1.8 is definitely the cheapest fixed-focus lens, which can be said to be the most cost-effective lens on the earth. The image quality is obviously better than all zoom heads, and the large aperture of 1.8 can't be achieved by all zoom heads. Taking portraits and playing with background blur is not comparable to zoom heads that cost several thousand yuan.

a large zoom for daily shooting, a mirror for the world, and a fixed focus to make up for the image quality and large aperture. And there is not much money. This combination is quite good.

It is recommended to put a backpack with a rain cover in the camera bag, and

it is recommended to put a stable and thick tripod.

In this way, many things can be done in daily shooting and professional shooting. Don't be redundant, a good scenery film, special effects film and night scene film, the role of the tripod is no worse than that of the lens. The lens is almost the same, and all the shots can be taken; Without a tripod, the light track, the starry night sky, the flowing water with silk effect and the night scene can't be photographed at all.
