Each has his own strengths, and Budweiser has a good image. However, because the depth of field of photos taken with long focal length is very shallow, even if the aperture reaches 22, it is only a few millimeters. Loop-free flash is more difficult to grasp, and long focal length is also beneficial. In order to catch insects, the success rate is relatively high, except for macro, which is a good portrait, so everyone likes Cynanchum atratum.

For Bai Wei, the short focal length gives a greater depth of field, and the relatively safe shutter is lower, which makes it easier to shoot. However, due to the short focal length, shooting needs to be close to the subject, so it is more difficult to catch bugs than Bai Wei.
