I want to sell a camera, but I don't know where to start. I love photography, whether it's going out for a walk or traveling, taking photos is essential.

Photography has entered the digital age, but it has not changed the fundamentals of photography. That is, the image quality (not the content) depends on the lens and photosensitive system, which used to be film, but now it is photosensitive CCD or CMOS, and processing software.

The 5 million pixels of the mobile phone only represent the photosensitive part and cannot explain or explain the image quality.

Since you are a novice, let's first understand the difference between card machine-micro-single-SLR.

If you have decided to enter the SLR, you need to know the characteristics of each brand and choose your favorite brand. Like Nikon and Canon.

If limited by funds, a good lens with poor fuselage (bull's head) is better in quality than a bad lens with good fuselage (dog's head).

Good lenses can be kept, and the fuselage can be changed. Especially in the digital age, new fuselage emerges one after another, and its value is always declining.
