A professional camera differs from a semi-professional camera not only in price, but also in other characteristics and functions. These are, for example, a matrix, a lens, various settings, a shutter, and more.
Instructions
Step 1
In a professional camera, the size of the matrix corresponds to the standard size of a film frame and is equal to 24 x 36 mm. For a semi-professional camera, it is 60% of the film format, and therefore it is almost one and a half times less. Naturally, the distance between the elements of the photosensitive matrix or the so-called pixels is less here. They heat up more, hence the lower quality of the images. By the way, hot pixels appear not only when heated, but also at high ISOs and long exposures. Moreover, if there are a lot of pixels in the matrix, this does not mean at all that this is good. The number of pixels is not a characteristic to look out for when choosing a camera. Professional equipment may have less of them than semi-professional equipment. It should also be borne in mind that among professional cameras there are cameras with so-called truncated matrices.
Step 2
The next criterion that distinguishes a semi-professional camera from a professional one is its lens. In professional cameras, the lens has better and faster optics. This, combined with the full-format sensor, delivers superb images. Typically, such a lens has an aperture that operates in the f 8-11 range. The lens differs not only in aperture ratio, but also in sharpness, wide angle of focus. Such lenses can be used on semi-professional cameras, but their potential is usually used only half. Therefore, amateur and semi-professional cameras have special lenses designed for smaller sensors.
Step 3
In semi-professional cameras there are preset scene programs, thanks to which amateurs can get good pictures in relation to certain shooting conditions, in professional cameras there are no such options. Because this equipment is used by people who know what they need and what they want from photography. They use their own settings, set the aperture, sensitivity and other characteristics themselves. Another difference between a professional camera and a semi-professional camera is the increased shutter resource. It is designed for such equipment for a certain number of operations. The manufacturer always specifies the resource of the shutter in the passport. Therefore, the professional photographer knows this figure and expects to take the required number of shots before the shutter fails.
Step 4
A professional camera is also distinguished by the presence of various accessories. For example, these are lenses. They are sold separately. They have different characteristics, and professional photographers buy them for specific needs. With removable lenses, for example, you can shoot objects located at long distances. If in a semi-professional camera the zoom allows the object to be brought closer, here the lens plays this role.
Step 5
Flash. They can also be purchased additionally, and they can be of different power and have different characteristics. Also on sale, a professional photographer can purchase various modules that will help him take high-quality pictures. For example, it can be a module consisting of a flat electronically controlled shutter, or a mirror module that allows the use of various lenses.
