Canon 500D needs a telephoto lens, about 5000.

To tell the truth, the lens with too wide focal length is below the price of 5000, and the imaging quality is average.

You can't be too greedy. Merchants will always create "exclusive" lenses for each type of customers. If someone wants a wide angle to a super telephoto, there is 18-200. Of course, the imaging quality is also average. Someone wanted a standard zoom, so they got 18- 135. Some people want to specialize in a certain focal segment, so they have a fixed focus lens.

I won't recommend the deputy factory lens to you, because I think the quality of the original lens of about 5000 is good enough to meet your landscape and portrait needs.

Recommended 1: Canon EF-S 15-85/3.5F-5.6F Features: 15-85 is an advanced zoom lens in APS-C format, which is equivalent to the focal length of 24- 136mm on your 500D, covering a small wide angle, with a golden portrait. It can be said that the scenery is suitable for both people, and the focal section is very practical.

Recommendation 2: Canon EF 17-40/4L. Features: This is Canon's cheapest red circle wide-angle zoom lens. The middle imaging is clear and sharp, the wide-angle full defocus imaging is slightly deformed, and the middle imaging is transparent and sharp. Compared with full-frame cameras, I personally think that 17-40 is suitable for half-frame cameras, because 17-40 is equivalent to the focal length of 27.2mm-64mm in 500D, which can completely cope with landscape and human body photography, and the imaging quality is good. (Portrait photography strictly refers to the portrait as the main body, supplemented by the background; Humanistic photography emphasizes the overall collocation of characters and backgrounds.

Both lenses are very good, and the quality is at the same level. 15-85 is more practical for 500D, but if you have plans to upgrade your camera to a full-frame camera, 17-40 is better and can be used in the future. Otherwise 15-85 will be wasted if it cannot be used in Quan Huafu. You can try the second-hand shop first, and then decide which one to buy. If you want to make up for the lack of aperture of the portrait, you can buy a 600-piece 50 1.8F fixed-focus lens, and 85 1.8F if you have the meter.
