Very important note:
Full manual lens, no electrical contacts → no auto focus → no anti-shake, more manual exposure experience is required, and the aperture cannot be adjusted
The camera must be set to M mode (pictured above) to use this lens, some may require "Shutter Release: No Lens" in the camera menu.
The camera does not display the aperture value and must be set manually on the lens body.
Telephoto manual lens
Live view focus is recommended for accurate focus. As with all telephoto lenses, a combination of sturdy camera mounts, sturdy tripods, good technique, fast shutter speeds, using a remote and mirror lock is recommended to avoid camera shake for best results.
No matter how good the autofocus is, sometimes manual focus is still the better option for shooting. When used in the right scene, it gives the photographer more control over the photo and, in some cases, can achieve effects not possible with autofocus mode.
