How to choose a commercial photographic equipment?

Mainly consider what effect you want to achieve with photos, in fact, it is the demand for quality.

What qualities do you need? Do you want perfect details?

What's the use of pictures? Do you want to zoom in at super high magnification?

Second, convenience.

Mainly consider what your job needs to achieve, in fact, it is the demand for efficiency.

The bigger and more complex the camera is, the lower its efficiency is. The higher the resolution, the slower the file storage speed. It is impossible for us to shoot sports events and climb mountains with a large-format landline weighing tens of kilograms. It's impossible to take only a few photos a day for some jobs with low profit margins, right?

Third, the control function mainly considers the characteristics of different shooting themes, which is actually the demand for creativity.

For example, a large format machine with tilt and axis shifting functions can change the focal plane and the viewing angle. For example, a super wide-angle lens can exaggerate the perspective effect and enhance the sense of space. Another example is high-speed continuous shooting function, high-definition video function and high-sensitivity noise control. ...

Fourth, price and maintenance.

Mainly consider their own development needs, in fact, is the demand for cost control.

The more expensive the camera, the more suitable it is. If you spend hundreds of thousands of dollars to invest in an 80-megapixel digital back and then use it to shoot e-commerce, you will never make money.

At the same time, we should also consider the convenience of camera maintenance and the price of accessories. The shutter life of 120 camera is usually 50,000 times, and there may be no new spare parts to replace it. The number of shutter times of SLR has reached 300,000 times. It only takes a few hundred yuan to change the shutter, and you can set foot on the journey again. The supply of spare parts is sufficient.
