Give the camera a score Z-MARK Detailed explanation of the camera product scoring mechanism

     camera And lens are the two core equipment of photography, and camera products have many characteristics, so it is difficult for us to interpret directly through simple data. In order to make it easier for consumers to choose equipment, we classify and score many characteristics of cameras and lenses, so that everyone can have a more intuitive judgment on camera products.

camera

Camera scores include six items: picture quality, color, appearance and control, shooting performance, video performance and cost performance.

Picture quality:

     The image quality score depends on the still image image quality of the camera, and is subject to many factors such as camera sensor size, camera sensor performance, camera processor performance and image processing algorithm. Specific reference items include: picture resolution, high sense and noise control performance, tolerance, etc.

Color:

The color score depends on the image color performance of the camera. Subject to the fuselage color management and image algorithm. Specific reference items include: image JPG straight color representation, color representation of different color presets, color representation of RAW files, etc.

Appearance and handling:

  Appearance and handling scores depend on the body design and handling experience. Specific reference items include: body portability, body design, control comfort, flip screen, touch control, viewfinder, button logic, etc.

Shooting performance:

The shooting performance score depends on the mechanical performance of the fuselage image. Specific reference items include: focusing speed, focusing accuracy, continuous shooting speed, etc.

Video performance:

The video score depends on the camera's ability to shoot video. Specific reference items include: video resolution, video quality, video noise control, video manipulation, video functions, etc.

cost performance:

    The cost performance score depends on the relationship between airframe pricing and performance.

Total score:

  The total score is not the weighted score of the above six items, but the total score of the camera body based on the camera body positioning and overall functional performance. The total score can represent the overall performance of the camera in the corresponding type of camera.

camera lens

The lens score is also divided into six sub items, including resolution/contrast, color, dispersion control, other optical properties, shooting performance, and cost performance.

Resolution/contrast:

The resolution/contrast score depends on the sharpness of the lens. Reference items include: progressive aperture sharpness performance of lens, sharpness performance of lens center and edge, etc.

Color:

The color score b depends on the imaging color performance of the lens. Reference items include: whether the image color is real, whether the image color is full, and whether the image color conforms to the visual perception, etc.

Dispersion control:

The dispersion control score depends on the dispersion suppression ability of the lens, that is, the purple edge performance. It mainly depends on the lens optical structure design and coating technology level.

Other optical properties:

Other optical performance scores depend on the optical design of the lens, and reference items include lens distortion, lens dark angle, and lens anti glare performance.

Shooting performance:

The shooting performance score depends on the size of the lens aperture and the performance of the focusing speed. The reference items include: virtualization ability, out of focus performance, focusing speed, etc.

cost performance:

Cost performance score depends on the relationship between lens pricing and performance.

Total score:

The total score is not the weighted score of the above six items, but the total score of the lens based on the lens positioning and overall functional performance. The total score can represent the overall performance of the lens in the corresponding type of lens.

Body × lens

According to the performance of the body and lens, we will get a comprehensive score. The final score depends on the above 12 sub scores, which will represent the final shooting performance of this equipment combination.

Lens applicable type

We have listed six categories of lenses: scenery, portrait, animal, macro, still life and architecture.

The shooting ability of the six corresponding lenses in different types of environments makes it easy for everyone to choose lenses according to their own needs.
