Your question answers itself. One will focus automatically, generally as soon as you press the picture-taking button half-way down, and the other one will not. The lens without auto-focus is called a manual focus lens. You have to look carefully through the camera viewfinder (or at the LCD) and rotate the lens barrel until the image appears to be sharp and in focus to you and then take the picture.
Auto-focus lenses CAN be used in the manual focus mode, but manual focus lenses do not offer an auto-focus mode.

Camera lens with Auto focus focuses on the subject automatically once you have aligned the camera properly. While the one without auto focus needs manual setting.
Auto focus lenses are more costly

Hi friend,
First tell you about non auto focus lens .....
It is lens with fixed focus ...for all distance ( like minimum to maximum) within lens's range you'll find every thing is sharp.
mostly these type of lenses are cheap and produces average quality photos... you have limitations on controlling depth of field.
where as auto focus lenses are focuses on subject and makes subject only sharp and other thing defuses . so you ll get better depth in picture. ... also depth of field can be varied, but you'll need advanced camera with aperture and shutter speed manual setting ,
Thanks .
Hope you've find this the best answer !

Auto Focus; It does all the work for you. Without Auto Focus "you do the work".

In Olden days there were no auto focus cameras. people had to keep turning a knob to focus an object.
Now Most of the cameras are auto focus.
But I recently met a jounalist who preferred to focus the objects himself and was turning the knobs, in his most sophisticated camera.

You should differentiate between a camera with AF capabilities and a Lens with AF capabilities. A camera with AF is compatible with Lens with AF. If either of them are not having AF, then they wont work and are not compatible with each other. If you try to fix a lens without AF to a camera with AF, it wont work. You have to manually focus.
