There should be no problem. The concept of 12 times is that under the condition of maximum zoom, helicopters flying overhead during air patrol can be clearly photographed. Generally, it is no problem to take a full-length portrait at a distance of 150 meters.

However, the problem is that 12 zoom will be very sensitive to the shaking of the photographer, so the landlord had better buy another tripod, otherwise 12 zoom is a bit tasteless.
