Is it legal to buy a SLR to change lenses? Why did SLR ruin your life?

The main difference between SLR and ordinary camera is that the lens can be changed. So we can simply divide the camera into a lens part and a body part.

Generally speaking, the quality of SLR fuselage is relatively high. As for lenses, in order to shoot good films at various focal lengths and control costs, most lenses have narrow application range, small focal length coverage and many fixed-focus lenses.

Ordinary camera is a whole, and the manufacturer has designed the best ratio of body and lens.

Therefore, under the same budget, the application area and comprehensive score of film quality of SLR are weaker than those of ordinary cameras.

Therefore, if you want SLR to be superior to ordinary cameras in terms of comprehensive scores of applicability and film quality, you must provide more budget.

What your classmate said can be understood in two ways:

1, bought a SLR, invested a lot of budget in order to make a good film, thus ruining the economy for a lifetime.

2. I bought a SLR, and I don't intend to invest much, but the film is not as good as the ordinary camera of 3 or 4 thousand, and the portability is even worse. I regret it for a lifetime.
