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.

One finger and two fingers are two completely different concepts. In order to distinguish, one refers to the optical lens and the other refers to the lens picture.

China's lens has gradually occupied a certain market in the market, mainly because the price is relatively low.

1.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.

2.e lens

(1) This lens is an ordinary industrial lens, and the pupil focal length needs to be adjusted manually. After the machine is installed, when the maximum magnification and the minimum magnification are manually adjusted, the image is equally clear. Those whose sharpness cannot be adjusted are regarded as defective products, and those with unstable factors such as jitter after adjustment are also regarded as defective products.

(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 0.7-4.5 times. ..

(4) Explain the definition according to the imaging reflection of the calibration block and the actual object.

3.l lens

(1) This lens is an ordinary industrial lens, and the pupil focal length needs to be adjusted manually. After the machine is installed, manually adjust the maximum magnification and minimum magnification, and the image is also clear. Those whose sharpness cannot be adjusted are regarded as defective products, and those with unstable factors such as jitter after adjustment are also regarded as defective products.

(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 0.7-4.5 times. ..

(4) Explain the definition according to the imaging reflection of the calibration block and the actual object.

4. Automatic zoom lens

(1) Automatic positioning, the pupil focus of the lens itself has been adjusted, and 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 0.7-4.5 times. ..

(4) Explain the definition according to the imaging reflection of the calibration block and the actual object.
