I want to buy a SLR camera to take cos photos. I hope parents can solve our problems ~

Pixels only compare the effect after magnification by dozens of times. Generally, 8 million pixels can be enlarged to A3 (about twice that of A4).

12 million is enough, but the image quality depends not only on the pixel level and the large optical system of the processing system of the machine itself, but also on the metering system of the machine. So if you have spare money, you can buy a SLR, and you can fool amateurs when you go out to shoot. It's enough to use the fuselage ferrule for the rookie lens. Pentax owns KX, you must have heard that the genuine licensed single ferrule and fuselage cost about 4000, and the parallel imports cost about 3500. The entry level of Canon Nikon is around 4,500 to 6,000, such as Canon 500D and Nikon D5000D3000. If you ask whether the current machine is competent, you should ask yourself, what does it feel like to use it at ordinary times? Will it be bad and hard to accept? Moreover, the later stage of photos is also very important, especially cos, which was added later. When you get on the SLR, you have to use the later stage.

No division is a bit messy, you can refer to the landlord. The main reason is that the camera pixel is not the most important factor now, and there is still a lot of knowledge in it, so if the landlord decides to buy it, he still has to go to the store to experience it himself. Good luck.
