Is the camera shooting well?

Reasons why condoms are cheap:

1。 The focusing motor is usually a low-end motor, and the focusing speed is not as fast as the bull's head. Gaps can only be detected when shooting moving objects.

2。 The aperture is not big enough. The blur effect is not as good as large aperture, and the weak light environment is not as good as large aperture.

3。 There are almost no advanced lenses. There are almost no aspherical, ED, fluorite advanced lenses. But it's not too bad to use.

4。 Low-end materials Most of them are plastic parts, but even a cow's head with more than 10 thousand yuan needs plastic parts. And I'm afraid of falling into a solid lens.

5。 Resolution is not high. In F8- 16, the resolution of the cheap head is similar to that of the bull's head, and the maximum aperture is not as good as that of the bull's head.
