Excuse me, prawns watching the air show, which focal lens is better for taking pictures of planes?

If you want to shoot an airplane in the air, you should have at least a 400 mm stable platform and a large aperture. 6000 yuan is basically no solution. I suggest giving up taking pictures and making a video as a souvenir.

In film and television, the lens has two fingers, one refers to the optical components used by film cameras and projectors to produce images, the other refers to the continuous picture taken from power on to power off, or the fragment between two editing points, also known as the lens.

P lens

(1) Automatically position the lens, and the pupil focus has been adjusted. It is necessary to check whether the definition from the maximum magnification to the minimum magnification is consistent and clear.

(2) Check the coaxiality, that is, the images from the maximum magnification to the minimum magnification are taken at the same position, and cannot be offset or offset too much, which is regarded as defective, and the lens must be replaced again.

(3) The optical magnification is 0.7—4.5X, that is, 9 magnifications ranging from 0.7 to 4.5 times.

(4) Judging the clarity according to the imaging reflection of the correction block and the actual object.
