Why are the photos taken by my camera striped?

Turn on telephoto anti-shake and zoom the lens to the longest. Turn on anti-shake and take a few photos at will, then play back and zoom in to the maximum on the screen to see if you are free.

Turn the lens to a wide angle, take a few pictures, and then do the same as above to see if the surroundings are clear. There are no dark corners. In addition, see if the deformation is serious.

Generally, this kind of camera is optical zoom+digital zoom. When the optical zoom is at its maximum, take a photo to see how much noise there is and whether the focus is accurate, and then pull it to the digital zoom to see how it works.

If possible, bring pure red, pure blue and pure green boards to see if the wide angle and telephoto of the camera are off color.

How fast does the wide angle change to telephoto? Fast speed is suitable for snapshot, but it is not conducive to precise fine-tuning. Slow speed is not suitable for snapshots, but fine tuning is easier.

Generally, the built-in flash of the camera will be blocked by the lens. See how much the shadow affects it.

Some cameras can have external lenses. This is also a point that should be considered.

Endurance. The display screen shows whether there is lag. The angle at which the display can be viewed. General visibility can reach 170. And whether it is necessary to turn the screen. Look at the camera from focusing to focusing to pressing the shutter to activate the shutter. The shorter the delay, the better.

It would be better if you could focus accurately in dark light.

Aperture range and shutter speed should also be considered. Generally, telephoto cameras are in full manual mode. Then the shutter speed should also be considered. The larger the aperture, the better.

Some people like light cameras. I think it's convenient to carry, depending on my personal emphasis. Speaking of photography, the heavier the camera, the better. Because for telephoto, the heavier it is, the less likely it is to shake. Jitter is to enlarge the telephoto.

Look at the starting speed. Turn on the phone, then welcome the screen, and then enter the normal shooting mode. The shorter the time, the better.

See CCD or CMOS, the bigger the size, the better. The same pixel, the larger the size, the better the image. Because the higher the pixel, the less light is received per unit pixel area, and if the signal is amplified again, it will produce noise (noise). The noise reduction of color system will affect the imaging quality.

Choose a few more and compare them. Take more pictures and see how it feels. Look at the operation interface. Some operating interfaces are very complicated and difficult to understand, while others are clear at a glance. Even some commonly used functions are placed on the camera surface.

Look at the dial above to see if the damping is moderate and if the buttons are too tight or too loose.

Pay attention to whether there is dust and impurities in the lens when you take the goods, especially the coating. Be sure to look at yourself. Stretch the lens to listen to the mechanical sound. The quieter the better. The smoother the lens is stretched, the better.

I don't know if I'm satisfied.
