SLR Xiaobai asks for help: 1. How is the outermost circle on the lens adjusted? Is it the focal length?

1. Most of them are focus adjustment, but they must be set to manual focus.

2. Of course, you can get the same image, but you have lost the spirit of photography (no post-processing, leaving beautiful scenes in an instant), and cutting will lose pixels and take time. At the same time, it also shows that your skills are too poor and need to be honed.

3. The adjustment button of the aperture is the same as that of the Otawa shutter, except which control button must be pressed to adjust it.

PS: Different brands have different settings, which are clearly stated in the manual.

SLR is not used to shoot. You must study the manual carefully first. Only by integrating man and machine can we have good performance.

It also depends on what you are pursuing. To what extent?
