I am a professional photographer. Please recommend me a SLR camera. Good quality, strong and durable. Thank you.

In camera positioning, only 1DX and D4 can be regarded as majors, including Hasselblad's over-framing.

1DX bare-metal 36600, 4D bare-metal 3.7W According to your requirements, taking Canon's as an example, full coverage of lens focal length segment requires at least:

16-35mm f2.8

24-70mm f2.8

70-200mm f2.8 is L.

Commonly known as big ternary, the focal length can basically cover all subjects, followed by more professional aspects, such as macro lens and fixed focus, wide angle, fisheye, axis shift and so on. Not everyone needs it, it depends on their own needs.

For example, the portrait king with big eyes in 85 1.2, each portrait has its own position to choose from.

The next step is to go to 5D3 or something, which is a quasi-professional level. 5D3+ ternary size is a good choice.
