How to use Nikon fixed-focus lens for photography

If it is AF 50 1.8D, you need to turn the aperture ring at the end of the lens to F22 and lock it, so that the camera body can control the aperture correctly. If it is AFS 1.8G, you can skip the above steps and use it directly after installation.

The easiest way to adjust the aperture is to give priority to the aperture. Use the combination shortcut key to set the shooting mode to A. For low-end cameras, it means that the rotating wave turns to A, and then use the front impeller to adjust the aperture parameters. If the low-end machine does not have a front impeller, use a rear impeller instead.

You can also turn the rear impeller, start the flexible exposure combination in program automatic P mode, and adjust the aperture and shutter at the same time.

It is not recommended for novices to use M mode, which is prone to exposure problems.
