18-55mm SLR lens can take the best image. What is the actual distance?

1, China's national standard GB99 17-88 stipulates that the test conditions of lens resolution are 135 lens magnification 1:50, 120 lens magnification 1:30, which are similar to international standards, so manufacturers are designing lenses.

2. A simple formula can let you know the best imaging distance range of a lens: lens focal length× 50× (1~ 3). For example, the optimal imaging distance of a 50mm lens is about 50mm×50×( 1~3)=2.5 to 7.5m Nikon China.

3. The closest focusing distance of the head is about 0.3m ..

To sum up, the optimal imaging distance of 18-55mm SLR lens is between 1-8 meters. Please confirm if it is useful to you.
