I'm going to buy Canon 70d. I don't know what kind of lens to match. Taking pictures of children, location, interior and snapshots are all good.

1, recommended for hanging up 17-55 lens. 17-55 is Canon's semi-transparent and semi-reflective mirror king, with a constant aperture of 2.8 (both famous mirrors with a constant aperture of 2.8). Its image quality is first-class, which can not only focus on portraits, but also take into account the scenery. It is much better than the range hood, but the price is small and expensive, about 5,000; If a longer focal length is needed, it is 15-85, with high resolution, small aperture and some aberrations. But the wide angle of 24 is very powerful and the scenery is very practical. The price is around 4000.

2, portrait shooting large aperture fixed focus lens is standard. Money is tight, some suggest Canon 50 1.8, a few hundred yuan, and the imaging is better. Some expensive ones recommend Canon 50 1.4, which is also very good, but the focal length is a little long after multiplying by the coefficient (equivalent to focal length 80), which is very convenient to use outdoors and a little difficult to play indoors. Economically, Sigma 35 1 4A (equivalent focal length 56, equivalent to monocular angle of human eye) is recommended. The imaging quality is comparable to the red circle, and the visual impact of the film is great. The price is about 5000 yuan, but we should pay attention to the selection to prevent it from running out of focus. If you can't choose to buy without guidance, you can recommend Canon 352.0IS Although the aperture is not as good as 1.4, the sharpness of full opening is very good and anti-shake is very useful. Holding110 seconds will not paste, and the price is more than 3000. Local tyrants recommend 35L or 24L with first-class picture quality (L stands for luxury). Local tyrants do not bargain.
