Questions about card machines and professional cameras

Correction upstairs: Professional camera ≠ SLR, but SLR is definitely more professional.

The key to measuring whether a camera is professional is its manual function and image quality. Image quality is easy to understand: a camera with very poor image quality will definitely be disdained by professionals. The manual function is the biggest difference between professional cameras and consumer cameras. Users of consumer cameras mainly use the camera to do some daily shooting, not to mention creation, so the design of the camera needs to be developed in the direction of ease of use. Therefore, the automatic functions of consumer cameras are very complete. I dare say that there are very few consumer cameras. Supports full manual operation. Fully manual is the biggest feature of professional cameras. Because professional cameras have risen to the level of "creation", they require photographers to have complete control over the images. At this time, full manual functions are needed - manual aperture, manual shutter, manual focus, manual white balance. Changes in each indicator can achieve completely different image effects. The photographer needs to have complete control over these indicators, rather than leaving it completely to the computer, otherwise the film will have no personality and "flavor" at all.

Professional cameras don’t necessarily use cannons. There are many very professional lenses that look very inconspicuous, such as the famous Nikon Portrait King 85mm f1.4, which is very inconspicuous, and there are also some magic-level mirrors, which are not necessarily cannons. Of course, the cannon is very bright when carried, but it is not necessarily practical. For example, when taking portraits, many people need a large aperture medium focal length lens, which does not look very conspicuous. For example, the standard Nikkor 50 f1.4 in my hand does not seem to be original. That dog head NB.

In fact, there are other professional machine types, such as rangefinder machines. Leica and Alpa rangefinder machines are quite well-known and quite expensive. The Malaysian 3 is the most affordable among the 135-frame digital SLRs, and its price is only enough to match an Alpa body without a camera back.

As for the clarity, it is definitely better, provided the aperture is the same. There will be a blurring effect under the large aperture, and what we are pursuing is an unclear and hazy feeling. In this case, the clarity is definitely not as good as the film produced by the small machine F16. When you zoom in to the maximum setting, the clarity is much better than that of a small camera. There are two reasons: the lens aperture is large, and the size of the photosensitive element is large, the distance between pixels is large, and there is little mutual interference. This is why professional cameras are so clear. The important reasons are that the accuracy and noise control are better than those of small machines. I have never heard of what ND106HD is, maybe NV106HD, Samsung Blues. Although Samsung also makes SLRs, no one will use Samsung in the professional field. For the optical industry, Samsung is obviously too young, and SONY is too young. Optics is an industry that requires accumulation. Therefore, the currently recognized professional imaging manufacturers are century-old companies such as Nikon, Canon, Leica, and CZ. The 106HD is not a professional camera and the lens cannot be modified.
