I want to buy a SLR digital camera. I understand.

A single battery seems to be too expensive now, and the options are relatively small. The more popular 16-megapixel SLRs are 550d and d7000. It depends on your budget. If you don’t have a lot of money, you can just buy the whole thing. As for which lens to use, it depends on which camera body you use. The range you mentioned is too large to give you any suggestions. In addition, SLR cameras are basically upgraded every 18 months, so it is unrealistic not to reduce prices.

In fact, full frame and non-full frame each have their own meanings. Nowadays, a camera with a sensor size of 24mm*36mm is said to be a sensor of a full-frame (that is, traditional 35mm film size) non-full-frame camera. It is smaller than the full frame, so the field of view seen at the same position and the same focal length is also smaller than the full frame. Therefore, the biggest advantage of the whole camera is at the wide-angle end, because the already very wide 24mm lens in the whole camera can no longer be called a wide-angle lens in non-full cameras, and the wide-angle lens of the digital SLR is relatively lacking.

I think when buying digital products, you need to match your needs. Ask yourself

1. What resolution do you need?

2. How often do you want to upgrade< /p>

3 Do you need a small SLR (compared with cameras like Leica m9) SLR is really inconvenient

4 What functions are needed

Then decide whether to buy a full set or Not all of them. Just suit yourself.
