I want to buy a SLR for taking photos of fashion models professionally. It needs high pixels and a lens.

In fact, the pixels of the camera are not important now. A camera with100000 pixels or more can be competent for general shooting tasks, because a camera with100000 pixels can enlarge photos to about 20 inches.

So, it depends on what you do. Take a professional fashion model, how much will the photo be enlarged? Is it for display or advertising? Generally speaking, almost all SLR cameras can do it now. It depends mainly on your budget. If it is 1 0,000 yuan, you can consider mid-range models, such as Canon's 50D and 60D, with 15-85 lens or 50/ 1.4 lens (or Nikon's D300s body and corresponding lens; If you have 30,000 pieces, you can consider Quan Huafu models, such as Canon's EOS 5D MARKII with EF24-70/2.8L, and the price without accessories is around 26,000 (of course, you can also choose Nikon's D700 and corresponding lens).
