Which camera works better? Sony or Canon? Preferably below 5000. How much is the camera used by professional photographers? I really want to learn photography.

Recommend Canon's SLR. 550D can be considered for 5000, and Nikon's is also very good. The camera body of a professional photographer is generally around 50,000. For example, Canon's Dasan III (1Ds Mark III) and Nikon's D3X, some useful institutions use Hasselblad, and the prices are even more exaggerated. In real life, most photographers we meet still hold high-end Quan Huafu SLR, such as Canon's 5D Mark II (invincible rabbit), 5D Mark III, Nikon's D700 and D800. The price of these cameras is about1.5-30 thousand yuan.
