Is it illegal to shoot a helicopter in flight with a mobile phone?

Shooting a high-speed moving object is manual focusing ... but you don't need to focus on this object. The specific steps are as follows: first, predict the route of the aircraft ... and then manually focus on the upcoming route of the aircraft in advance. Finally, when the plane flies over the area where you focus in advance, just press the shutter. PS: If your hands are unstable, you'd better use a tripod ... Hehe, a supplement: Landlord ~ First of all, don't be so superstitious about Zeiss. Zeiss's instruments are used at two levels: military and civilian ... and then there is the machine problem. In terms of performance, 40d is slightly better than a700, what's more, what the landlord needs now is air show shooting, and it is even more important to use 40d. Because the 40d continuous shooting with 6.5 frames per second is the fastest in the mid-range SLR ... it helps you shoot high-speed objects. Finally, the lens problem. Zeiss hasn't heard any news about this recently, so only insiders know whether it will be built ... but I can guarantee that even if it is built, the landlord wants to buy a better one, at least zoom in to 300 W and focus at least 300 ... Is the landlord a full-time photographer? If not, there is absolutely no need to buy it ... Besides, this kind of lens, A700 can't play all the effects. To play it all, it must be the A900 ... (listed at the end of the year). In contrast, Canon's L-class lens is very real, and the effect will never be worse than Zeiss. I made an evaluation with my classmates. The evaluations are Zeiss 85 f 1.4 and Canon EF 85 f 1.2L II USM, respectively, using A700 and 40d ... portrait photos. The effect is obvious. Canon won, and the portrait taken by Canon was cut ... The lens blur ability is terrible. Therefore, the 300-end L-class lens will not be worse than Zeiss, because don't forget the strength of Canon lens.
