Ask a mentally retarded question, does it take a long time for a photographer to choke before taking pictures? Can't ordinary mid-range micro-single and SLR take pictures?

When you say long guns and short guns, you mean the lens, not the fuselage. Photographers don't have to use that kind of big lens, and they find it inconvenient. What kind of lens to use depends on the shooting environment and shooting needs. Of course, when shooting sports, stage performances, wildlife and other subjects that need to keep a considerable distance, you can only choose that kind of lens, and there is no good way. As for the fuselage, in fact, the same specifications of the fuselage, whether domestic or professional, are similar in image quality performance, but the professional fuselage is often superior in handling, stability and protection, so photographers really prefer to choose a professional fuselage, but this is not necessary.
